TD-H3 VHF/UHF Radio
News Flash: I found a cheap economical VHF/UHF handheld that I really like. The TIDRADIO TD-H3 is getting a lot of attention from YouTube reviewers. You can think of this as an improved Baofeng UV-5R, with a few key features that grabbed my attention:
Improved Look and Feel: This radio looks like a quality product, much improved over the plastic Lego-style industrial design of the Baofeng radios. It feels and looks solid in my hand. The rubber duck antenna seems higher quality although I haven’t tested its performance.
One Radio, Three Modes: The firmware can be set to operate in three distinct configurations: Ham (transmit on 2m and 70cm ham bands only), GMRS (standard FCC Part 95 GMRS channels) and Normal (which is basically unlocked). You can easily switch between these modes but the memory information does get reset. So in most cases, you will need to reprogram the radio with your favorite frequencies after you change modes. The exception might be GMRS mode which will reset to standard GMRS channels. The flexibility of these three configurations is quite nice: The Ham configuration is great for normal ham operating with no risk of going “out of band.” I can loan out the radio in the GMRS configuration knowing that the user won’t inadvertently transmit on the ham bands. And, of course, the Normal mode provides access to a wide range of frequencies, to be used carefully, abiding by the relevant regulations.
USB-C Connectors: The radio battery has a USB-C connector for charging and a USB-C connector for programming (with Chirp or the TIDRADIO app). This may seem minor, but using a common industry-standard connector is a huge convenience factor. For example, I recently packed my gear for a trip and found that the USB cables I normally carry for my smartphone and tablet will handle the TD-H3 just fine. So there is no need for a drop-in cradle, extra charger or special programming cable.
Video Reviews
Apparently, TIDRADIO gave away a gazzillion radios to ham radio Youtubers and asked them to review the radio, so you’ll find many reviews out there. This one gives a good overview of the radio’s capabilities:
This radio is not quite the One Radio To Rule Them All, primarily because it won’t be convenient to switch between configurations. However, the radio is legal for GMRS and ham use, so that is definitely a plus. Will the FCC object to this kind of flexibility? Who knows, but they haven’t so far.
This video from KS6DAY shows how to switch between the three radio configurations:
Some Problems
Early on, several Youtube reviewers reported high spurious emissions coming from the radio. They fed this information back to TIDRADIO, who responded with a design change and some updated radios to test. They appear to have corrected this problem…the three radios in my possession tested out fine. There have also been some complaints about how a few features work and TIDRADIO has responded with a firmware upgrade to address those issues. So we can give TIDRADIO a good grade for responsiveness but poor marks for releasing a product that was not completely baked. Unfortunately, there are many videos in the etherwebz claiming the radio has problems and it is a challenge to sort through the actual situation today.
To become familiar with the radio, KS6DAY has a series of videos that explain how to use the radio. Lots of good information here:
Summary
As I mentioned, I have three of these radios and may be going back for more. For me, they fit the role of that “spare radio” that is kept in my vehicle, loaned out to other people, or just stored away for When All Else Fails.

FCC Enforcement Actions
When teaching ham radio license classes, I often get asked whether the FCC enforces the Part 97 rules and regulations. That is, how likely is it that the FCC would come after me if I violate the rules? This same question surfaces concerning the General Mobile Radio Service (GMRS).
This morning, I looked at the FCC Enforcement Actions page, to see what’s there. First off, there are a ton of actions against unlicensed FM broadcast stations, in response to the PIRATE Act pass by Congress in 2020. There are also many actions against people operating RoboCall systems via telephone. If you find yourself bored, go ahead and read through these enforcement actions.
Here are some actions taken by the FCC concerning Amateur Radio and GMRS in the past few years:
In June 2022, the FCC sent a Notice of Violation to David Dean, K0PWO, concerning a continuous carrier signal on 7.033 MHz from a remote station near Fairplay, Colorado. I recall there being a ruckus about this incident in the ham radio community but I did not know it resulted in a Notice of Violation.
In June 2022, the FCC issued a Notice of Apparent Liability (FCC talk for “we are fining you”) of $34k to Jason Frawley, WA7CQ. The FCC says that Frawley used his ham radio to transmit on frequencies allocated and authorized for government use during the Johnson wildfire near Elk River, Idaho.
In November 2022, the FCC sent a Notice of Violation to David Dean, K0PWO. (This is the same person with the stuck transmitter in June 2022.) The FCC received a complaint from the State of Colorado that someone (later found to be Dean) had an illegally cloned radio transmitting on the State’s digital trunked radio system (DTRS) without authorization.
In June 2023, the FCC issued a Notice of Violation to Martin Anderson, GMRS WQQP653 in Vancouver, WA. This relates to a stuck transmitter, apparently due to a faulty transceiver at a repeater site. It transmitted continuous, unmodulated signals on the frequency of 462.725 MHz.
In August 2023, the FCC issued a Notice of Violation to Jonathan Gutierrez, GMRS license WRTD259 in response to a complaint of intentional interference to a 462.625 MHz repeater in Mt. Holly, Pennsylvania.
In August 2023, the FCC issued a Notice of Violation to Alarm Detection Systems, licensee of radio station WQSK406 in Louisville, Colorado. This is not ham or GMRS-related but involves a business band radio on 460 MHz. Apparently, the company continued to operate legacy “wideband” FM radios after the FCC required business band radio users to switch to “narrowband” radios (12.5 kHz channels). I found this interesting because it is an action related to the use of improper radio gear and emission type.
In May 2024, the FCC issued a Notice of Unlicensed Operation to Skydive Elsinore, LLC, a skydiving company in Lake Elsinore, CA. This company was transmitting in the 70 cm amateur band on 442.725 MHz without a proper license.
From these notices, we can see that the FCC does enforce amateur and GMRS rules, but not as often as we’d like to see. Usually, the situation has to be a big nuisance before it escalates enough for the FCC to take action. If you make a simple mistake once or twice, you are highly unlikely to be cited. If you are a more consistent or flagrant rule breaker, then you might get a visit from the FCC.
Remember that the ARRL has the Volunteer Monitor program, operating under a formal agreement with the FCC, that can assist with on-the-air violations.

FRS3 For Colorado Backcountry
The Colorado Search and Rescue Association is promoting FRS (Family Radio Service) Channel 3 as “the default during backcountry search and rescue (backcountry SAR) emergencies.” FRS channel 3 is the same as GMRS (General Mobile Radio Service) channel 3. There is more GMRS info here. To keep things simple, no CTCSS (“privacy code”) is used…carrier squelch only. See the CSAR announcement here: FRS Radio Use for Backcountry.
For backcountry exploring, it is important to emphasize self-sufficiency and to avoid reliance on electronic gizmos that may fail. Avoiding an emergency situation is way better than having a device to call for help, which may be many hours away. See this article for a discussion of The Ten Essentials for Hiking.
Still, the FRS3 concept has merit. Many backcountry hikers already carry FRS or GMRS radios, so designating a preferred channel makes sense. My read on this is that randomly calling for help on FRS3 will not be very effective due to the limited range of FRS radios. However, it does not hurt to try. More likely, FRS3 can be used for local comms once Search and Rescue crews have been deployed and are within a few miles of the party in distress.
Ham radio operators may want to carry a handheld transceiver capable of transmitting on 462.6125 MHz. For emergency use only, of course.

Make The Contact
Regarding the important religious issue of ham radio modulation, I am agnostic. There is room in ham radio for many modes including CW, AM, FM, SSB, RTTY, DV, FT8, and more. This springs from my belief that the universal purpose of amateur radio is to have fun messing around with radios. As long as you are obeying the FCC rules (or equivalent), having fun, and not being a pain to other radio hams, you have my full support to choose whatever emission type you prefer.
When I mention the use of FT8, I often get comments from folks disparaging the mode. Usually, the complaint is that FT8 is too impersonal or that it relies too much on DSP and computer power to get the job done. Those are actually valid complaints. Most of us would rather hear the voice of the other operator (or their CW fist) and have just a bit of interaction with them, even if it’s just “Roger, Five Nine Colorado.” (JS8 is a digital mode that provides a bit more interaction, so that is another option.) And there is no question that we depend on the technology to make the contact (more so than your typical CW or SSB contact.)
Recently, I wrote about how I need A Reason To Get On The Air, which is all about going after some particular operating activity whether it be DXCC, SOTA, POTA or whatever. The main objective of such activity is making a radio contact. Can I get my electromagnetic wave through the ether and have it arrive at the other station’s location? Then can they get their signal back to me, so we have a legitimate contact. If so, I get to check the box on that radio contact. See What is a Valid QSO?
I am not alone because many hams are voting with their transceiver settings on a daily basis, choosing FT8 over other modes. They are prioritizing making the contact higher than having a robust conversation with another radio operator. In fact, I sometimes hear radio amateurs comment that they prefer not having to deal with the standard chit-chat that provides a signal report, name, location, etc. They would rather just get the contact and put it in the log.
And it’s not just FT8. Many examples of ham radio operation emphasize making the QSO, independent of the mode used: SOTA, POTA, IOTA, DXCC, WAS, WAZ, contesting, EME, meteor scatter, and more. Meteor scatter is an interesting one…on the surface, it is not the most exciting activity. Sometimes it feels like watching paint dry because it may take 20 or 30 minutes to complete a contact. However, there is clearly a challenge here…can I bounce a signal off a meteor trail and have it reach the other station? And can I hear the other station’s reply? I’ve worked new stations and grids on 6m and 2m using this method and I enjoy getting a new one in the log. Perhaps not much different than busting through a CW or SSB pileup trying to work a rare DXpedition.
So keep having fun messing around with radios, using whatever mode you like.
And make the contact…we can talk about it later.

A Reason To Get On The Air
I don’t need much but I do need a reason to get on the air. This can take many forms as I wrote in this blog post some time ago. I see quite a few new hams struggling with the problem of “I got this license but now what?”
Operating goals or awards are a fun way to keep focused on accomplishing something via ham radio. Really, it’s a specific reason to get on the air and make radio contacts. I am not big on idle chit chat via the radio (“the weather here is 65 deg and raining”) so having a reason to make contacts helps me get on the air. I’ve tended to pursue awards in a serial manner…once I hit some level of accomplishment, I usually declare victory and move on to something else.
Way back in the wayback machine, the first award I pursued was Worked All States (WAS). It does take some effort but I was pretty active on the HF bands at the time, so many of the states just showed up in my log. But to really drive it home, I kept track of which states I still needed and actively looked for opportunities to work them. Later, I pursued Worked All Continents (WAC), which obviously requires working some DX. But then I decided that if I had any DX cred at all, I needed to get DX Century Club (DXCC). Recently, the popularity of FT8 has been a game changer and I currently have about 175 entities confirmed (thank you, Logbook of The World). I don’t chase paper QSL cards anymore, which is just too much trouble for a Slacker DXer.
The VHF and higher bands have always been a passion for me, so I pursued the VHF/UHF Century Club (VUCC) awards. First, it was 6 meter VUCC, the easiest one to get. A really good run during the ARRL June VHF contest can produce the 100 grids you need for the award in one weekend. Later, some mountaintop activity resulted in 10 GHz VUCC. At one point, I got into working the LEO satellites and confirmed the required 100 grids for satellite VUCC. (Hey, Technicians, this is something you can do right now!) I still don’t have very many grids confirmed on 2 meters, so that one is still calling to me.
Summits On The Air
If you read my blog, you know that Summits On The Air (SOTA) is my number one activity lately, both activating and chasing summits. This is a natural fit for me as I’ve enjoyed mountaintop operating in various forms, mostly on VHF and UHF. (See my SOTA blog postings.) My hiking partner and wife, Joyce/K0JJW is almost always activating with me. Her #1 ham radio activity is also SOTA. We both achieved Mountain Goat status (1000 activator points) using only VHF and higher frequencies. (Technicians can have a lot of fun with SOTA on VHF!)
The SOTA program has a wide variety of awards, supported by a comprehensive database used to record SOTA radio contacts and keep track of the scores. It is not really a competition but there is friendly rivalry between SOTA enthusiasts as they monitor each other’s posted scores. Here are the “badges” that pop up when I check my SOTA info.
Parks On The Air
In the past few years, we have added the Parks On The Air (POTA) program. It turns out that not all regions of the country have interesting SOTA summits but they all have state or national parks. This fits nicely into our outdoor hiking/camping/4WD activities.
Many of our SOTA activations are in parks (national forests, national parks and state parks), so we usually try to make the SOTA activation count for both programs. This means that many of our POTA activations are done using VHF/UHF only, if from a summit. More commonly, we use the HF bands for POTA activations. Our standard POTA setup is a Yaesu FT-991 driving an endfed wire antenna, usually on SSB or FT8.
POTA also has a great database, good tools and plenty of awards available. Here’s what shows up on my POTA awards page. Just like SOTA, POTA is not a competition but it is interesting to see what other hams are doing and compare you level of activity.
So those are my thoughts.
What motivates you to get on the air?

Data on Amateur Radio Operating Habits
Most active hams know many other radio hams and we think we have a handle on what ham radio activity is occurring. But our look into the hobby is limited by who we hang out with and the sources of information we consume. Also, we can see that the ham population is aging which is going to have a significant effect on amateur radio activity but we may not have any reliable data.
In general, the amateur radio community lacks publicly available data on amateur radio operating habits and demographics. So I was excited to see the Operating Patterns Among Canadian Amateurs authored by my friend Frank Howell, K4FMH. This report analyzes the survey of Canadian hams done by Radio Amateurs of Canada (RAC) in 2021. Frank is a Real Researcher, so he applies generally accepted statistical techniques to aid in understanding the data. I would have preferred a study of US radio amateurs, but it seems reasonable that the operating habits of Canadian hams would be similar to US hams (and perhaps a good proxy for other developed nations). Anyway, it is the data we have and it is probably useful. I encourage you to download the report and read it for yourself, but I’ll comment on three findings from the report that strike me as significant.
Digital is really popular
The figure below is a chart that shows the popularity of different operating activities. No surprise, Casual Operating and Traditional Voice Modes score very high. But number three is Digital Modes, almost as high as Traditional Voice Modes. Depending on your operating habits, you may be thinking “well,of course, digital is very popular” but others may think “really, people like doing that?” The report also points out that digital operation is correlated with age, with younger hams using digital more than older folks.
Ham careers can start at any age
Another interesting finding is that the classic stereotype of “young person discovers radio and pursues it as a lifelong hobby” is not universal. The report shows that people enter the hobby at a variety of ages and then pursue it with varying intensity. Quoting the report:
Thus, these data illustrate that our conventional image of the amateur who gets licensed early in life and maintains that hobby activity throughout is largely a stereotype. Although it is one based upon real-world examples who fit it ideally.
I see this when teaching Technician license classes. The ages of our students typically span a wide range, including youth, but many of them are over 40 years old, entering the hobby later in life. In addition, we have quite a few students around retirement age (60 or so) looking for an activity to engage in during retirement.
The ham population is aging
You are probably thinking: duh, of course it is aging. The report puts some numbers on it, comparing it to the general population in Canada (see figure below).
Clearly, the ham population is over-represented in the age groups above 50 years. Often, the conventional thinking is “we have to get the kids involved,” which is a worthy thing to do. However, the report warns us that this won’t be enough:
This pattern has two clear implications for amateur radio in Canada. One is that the age groups of 60-80 years of age, now dominating amateur radio as the RAC Survey suggests, will simply disappear as they age-out to infirmity or becoming Silent Keys. Yet, their non-ham radio peers are scheduled to grow in number. (A recruitment focus on late-in-life hams is a clear policy for RAC to consider.) A second implication is that teens will be a relatively scarce recruitment commodity in terms of the age pyramid. There will simply not be enough of them to replace those Baby Boomers now dominating the hobby, regardless of the recruitment resources directed toward them.
This is not a call to give up on recruiting youth:
This should not be misconstrued to suggest that it would be a waste of time to expose young people to amateur radio as a recruitment method.
More to consider
This post highlights three findings that I found to be interesting. There is much more information included in this report and I encourage you to read and ponder it. I’d certainly like to see more of this kind of work published, especially for the ham population in the US, Europe and Japan. I find the demographic analysis compelling, indicating that we will see a decline in the number of radio hams in the next decade or so. We can probably reduce this decline but not stop it (my opinion, worth at least what you paid for it.). Perhaps the way to think about the challenge is to focus on having a smaller but more vibrant and active amateur radio community in the future.
These are my thoughts for today.
What do you think?
