Flair For Your Radio Bag

Yet another bag for carrying radio gear

The world is divided into two groups: Bag Guys and Not Bag Guys. (I am using “guy” as gender neutral.) I am a Bag Guy. I am always looking for just the right backpack, computer bag, luggage or duffel bag. For example, I’ve got this special bag, a backpack, that I use for hauling my portable VHF/UHF radio gear. You might call it a Go Bag but it really only has radio gear in it.

My gear for Summits On The Air (SOTA) has expanded a bit, so obviously it was time for a new bag. I decided to buy this backpack because it has solid construction and plenty of pockets. I don’t plan to actually use this as a backpack, it will be more of a “toss the gear into the back of the Jeep” bag…but having backpack straps on it will come in handy. This bag will carry spare cables, chargers, batteries, etc. that I want to keep with the radios but won’t take on the trail.

 

USA and Colorado state flags

I chose the “Coyote” color for two reasons: 1) my kids keep making fun of me for always buying black bags and 2) it doesn’t show the dirt as much.  This bag came with a US flag attached to it, which was a nice bonus. I kind of like patches but I don’t actually attach them to my gear or clothing very often. My interest in any particular patch changes with time and location. And I don’t want to put on so many of them that I look like a Boy Scout with a sash full of merit badges.

Well, the military has solved this problem through the use of hook-and-loop attachments (“Velcro”) on tactical gear. Feel like a little flair? Slap on a patch. Get tired of it, just take it off. Brilliant. For a little background on proper flair, see this video clip from the movie Office Space.

Label your bag

I thought the US Flag was pretty cool, so I found a Colorado flag to add to the collection. Then I got to thinking about using patches to label the bag. I noticed the many vendors that make custom text patches (often referred to as “Name Tapes”). These work great for labeling bags, pouches, etc. I ordered mine from a third-party on Amazon: 3 Inches/Hook Fastener/ Personalized Custom Name Tape

Of course, another option is to put my name on the patch. By name, I really mean name and call sign. If there are a pile of radio bags, everyone will know which one is mine. This is where it can get tricky because my call sign has a zero in it and not all vendors know how to handle the slash-zero thing. I decided to give it a try by just inserted a slash-zero character into the entry field on the web page. As you can see in the photo, it worked out just fine.

 

Do a little websearching and you’ll find plenty of military/tactical gear that has hook-and-loop fasteners built into the design. But, you may already have your favorite backpack that doesn’t have this feature. No problem, go ahead and attach a strip or two of the fuzzy (loop) material to it and you can slap your favorite patch on it.

I can already see how this may will get out of hand. There are so many packs, pouches, bags, hats, jackets that could use some proper labeling, or maybe just a little flair.

Weekly Propagation Summary – 2018 Feb 05 16:10 UTC

Weekly Propagation Summary (2018 Feb 05 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Feb 05 0144 UTC.

Highlights of Solar and Geomagnetic Activity 29 January – 04 February 2018

Solar activity was at very low levels from 29 Jan – 03 Feb. Low levels were observed on 04 Feb as new Region 2699 (S04, L=171, class/area Hsx/080 on 04 Feb) produced a C1 flare at 04/2024 UTC. The region also produced numerous B-class flares after rotating onto the disk. No Earth-directed CME activity was observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 29 Jan with a peak flux of 130 pfu observed at 29/0005 UTC. Normal levels were observed from 30 Jan – 04 Feb.

Geomagnetic field activity was at mostly quiet levels with isolated unsettled intervals observed early on 30 Jan and again late on 31 Jan.

Forecast of Solar and Geomagnetic Activity 05 February – 03 March 2018

Solar activity is expected to be to be at mostly very low levels with a slight chance for low activity through 16 Feb due to the emergence of Region 2699. Very low levels are anticipated from 17-28 Feb after the departure of Region 2699. A slight chance for low levels is possible from 01-03 Mar due to the return of old Region 2699.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels from 05-14 Feb and again from 26 Feb-03 Mar. Moderate levels are likely from 15-25 Feb due to influence from recurrent CH HSSs.

Geomagnetic field activity is expected to be at quiet to unsettled levels on 05 Feb, 15-17 Feb and 20-22 Feb, with isolated active periods likley on 16 Feb. This activity is due to influence from recurrent CH HSSs. Mostly quiet conditions are expected for the remainder of the outlook period.

Retirement planning time!

Time to start planning for retirement, if you say it fast the end of 2019 is not that far off and that is my official retirement date! As the old saying goes and it's so true "Where did the time go?". I will be 59 at the time of retirement and with good health I should be enjoying this next phase of my journey for some time. So where does ham radio fit into my plans? I could say that once retired I will have all the time in the world for radio......BUT........I have been off for extended holiday periods and at that time I thought I had all the time in the world. It seems even when not working you can still become very busy and radio gets crowed out with other "things" So one of my goals is to make sure I put time aside for radio time.
One of our big retirement plans (as Julie retires the same time I do) is that we are picking up and moving to the UK! We both are citizens of that great country and will be spending our retirement years there and also traveling abroad from our UK home homebase. This brings me back to ham radio again, at this point in Canada I hold an advanced ticket which includes 12 wpm CW. I have been all over the Ofcom (Office Of Comunications) site in the UK looking for information on how my transition regarding my amateur radio licence will be dealt with by Ofcom. Those of you over in the UK reading my blog maybe you can add some insight for me in regards to when I move will my Canadian licence transfer to a UK licence, do I have to start over or a combination of both? I did try my best in going over the Ofcom website but to be honest it is a confusing site.

Noisy power supply — Heathkit HP-13

Resurrecting a Heathkit HP-13

As seen in my previous post I've taken the dark plunge into the world of tube radios.  I want to start restoring my Heathkit HW-101, but before I can do that I must be able to power it.  As I previously wrote, I taken the road less travelled and got an old (circa 1965) HP-13 mobile power supply because I thought it would be nice to power the radio from a 12v source rather than mains. 

Unrestored HP-13 with broken solder joints and trashed capacitors


Well there seems to be a reason these don't seem very popular... I'll get to that.

I found a very nice article from RDF-Electronics regarding modernizing the HP-13 power supply.  That document includes the components and part numbers for everything you will need to restore your HP-13.  My parts arrived from Digi-key and I began snipping and desoldering the old component off the PC board.  The replacement electrolytic capacitors are all much smaller and have radial rather than axial leads.  That makes placing things on the board require a bit more creativity.  

HP-13 Schematic

The only truly problematic components to replace was replacing the twin positive axial lead electrolytic (C11) with two electrolytic capacitors (space issue) and replacing the C1 and C12 due to the tricky wiring around the transistors. 

The orange cap on the left under the Q1 (C1) was tough to replace with a much smaller radial lead capacitor

The article suggested replacing the original 100 uF/50 V capacitor with a 4,700 uF/35V to better control ripple.  The article goes into quite a bit of detail concerning his testing of ripple using an oscilloscope.  Finding room for that big cap and it's accompanying filter disc required a bit of creativity as seen below, where it's laying on its side between two of the rectifier caps.

I will glue all the caps to the board before I put the power supply into service.



New capacitors and diodes

I replaced all the electrolytic caps and diodes.  The diodes might have been ok but they are blocking over 300 volts each and a single failure would let the smoke out for sure.

Out with the old

In with the new
All the resistors except one 100k 2 watt were ok.  So I only replaced that resistor.  The 1.6kv disc caps even measured ok.

The internals look a bit different now with the new caps standing up where the old, larger axial lead components laid flat.

Ready for testing

Testing

After performing resistance and continuity checks I buttoned it up for the test.

The Noise

I had no idea how audibly noisy this power supply would be.  The switching that occurs in the transformer creates a very loud whine.  I understand why hams would install these in the trunk.  There's no way you'd be able to stand this for long if it was sitting next to your station.

I have a longish intro in the video.  Skip towards the end to hear it powered up... turn your volume down when you see the "hearing protection" sign come up in the video.


Conclusions

This was a good learning experience.  I learned about high voltage transformers and got some practice restoring older equipment.  I practiced electrical safety and didn't kill myself, so I'm pleased about that.

I now have a power supply I could use from a sturdy 12v source if I needed it, BUT due to the noise in operation I'm going to look into restoring a HP-23 which runs off house mains (AC) and is mostly silent. 

I'll keep this on the shelf waiting for a day that I need to run the HW-101 mobile. 


That's all for now

ETH096 – School Club Roundup, Hamvention Update and More…Everything Ham Radio

Hello everybody! In this episode of the Everything Ham Radio Podcast, I am stuck by myself talk to yall. I unfortunately didn’t remember that I my next scheduled update was due until 4pm the day before. So I worked all afternoon, while at work, trying to figure out what I was going to talk about. When I got off work at midnight, I ran home and did my couple honey-dos and then went straight to recording the episode.

So what is in this episode?

First off, I made a mistake! Yea, I know, nobody is suppose to make mistakes right? Well, in my last episode I did. In last episode, my semi regular co-host Ian KM4IK and were talking about the big stink that was doing on with some things that the ARRL Board of Directors were going to be voting on. Neither one of us were really up to speed on the whole thing as much as we should be, but we did our best, and we even said that we weren’t. However, after the episode I did receive multiple emails saying that I said something wrong, so I corrected it in this episode.

With that out of the way, I went on to talk about an upcoming event called the School Club Roundup. It is this month only a few days away actually. The event run February 12-16, 2018. It is an event that is geared for school amateur radio clubs to get on the air and make some contacts. Even if you are not in a school club though you can still get on the air and make contact with the school clubs that are on the air and help them make the points.

After that, I moved on to Hamvention. Another correction from last episode. Well I say correction, this time it wasn’t me though. In last episode we talked about how a new building was going to be built and available by this Hamvention. However, this week, the Hamvention committee released that it wouldn’t be started on until later in the year due to a material shortage.

I wrap up the episode reading some emails that I have received over the past few weeks. The last episode of 2017, I told yall what my plans were for 2018 and asked what some of yalls were and also asked some questions about what were yalls opinions on how my show is. I got a few responses, wish I would’ve had more though.

Until Next Time Yall…
