Jason Johnston, KC5HWB, announced today that he’s launching a new video series called Ham Radio 2.0. To help fund the project, he’s also launching a Kickstarter campaign to raise $5,000 in a little less than two months.

Johnston’s video podcast joins several other popular shows for hams including Ham Radio Now, AmateurLogic and Ham Nation.

This isn’t Johnston’s first radio-related venture. He sells radio equipment on his Grapevine Amateur Radio website and is a long-time blogger at Grapevine Ham Radio.

He says that his goal is to provide a wide variety of episodes including featuring new radio debuts and hands-on, how-to instructional videos.

Some of the topics he plans to cover include:

• New radio reviews
• Featured dealer profiles
• Hamfest reviews
• Coverage of DXpeditions and SOTA activations
• Tech talks
• Featured homebrew gear

Johnston hopes to leverage success he’s had with other ham-related videos. “With promotions, I see potential for getting tens of thousands of views on every video,” he says. “Promotion is the key, and will be my main focus with kicking the project off initially.”

Monday was spent finishing the coil winding for my present bench project, a 3-tube regenerative receiver. The receiver first appeared in the January '33 QST article, "Rationalizing The Autodyne", by George Grammer. I tried to stay true to the original design, both physically and electrically, as much as possible. Where period components were not available, they were manufactured. Several capacitor are 're-stuffed' cases and some resistors have been physically altered to resemble era-appropriate styles. The one deviation I made from the original circuit was to remove the B+ (200VDC) from the headphones by going to impedance-coupled audio, which blocks DC from the headphone circuit. After finishing the coils and doing a quick re-check of the wiring, I held my breath and applied the power.






Much to my surprise and delight, the receiver worked immediately. It took me some time to find the correct control settings and combinations that seemed best but eventually its operation became familiar. Here are a couple of short recordings, crudely made via connecting the computer across the high-impedance headphones, as I tuned across a somewhat noisy 40m band in the evening.







Now although the receiver appears to be working, I'm not 100% convinced that it is working as well as it should. It's difficult to know exactly how it should perform when at its best as it really can't be compared to any of our modern-day receiving systems. Just what did 'good performance' sound like in 1933?

I have some reservations about one of my tubes. It's a '78' from my junk-box stash and has a large red '?' inked across the glass envelope. I may order some NOS '78's or even some more modern '6D6's, to see how they perform. On the plus side, the oscillator seems very stable and there is absolutely no 'hand-effect' on tuning, a common problem with many regens. Peaking up the RF stage tuning causes no pulling of the oscillator but the '78', although a hot-performer in 1933, provides plenty of tube noise as well, if the gain is set too high. I think the main advantage of having the tuned RF stage is to add RF selectivity and eliminate any bleed-through from some of the blowtorch shortwave signals just up the band. Tuning seems best when its gain is set between fifty and seventy-five percent of maximum. The large drum dial, in combination with the small bandspread capacitor, spreads 40m across most of the dial and makes for easy tuning although there is a small amount of backlash.

Another thing I noticed is that it seems to be very receptive to spurious computer birdies, with the laptop sitting just a foot away. Perhaps its unshielded top and bottom are the cause of this as I don't hear any of the signals on my main station receiver.

Comparing it to the two-tube regen in my Paraset, the Paraset sounds much quieter and generally sounds more sensitive ... but it uses more modern tubes, '6SK7's, first introduced in 1938, five years after the '78'. The selectivity seems as good, if not better, than the Paraset, which I consider an excellent performer. The Paraset also sounds just as good as my National SW-3, which was produced in the early 30's ... so the new regen is likely not as quiet nor as sensitive as the SW-3, probably the best simple regen of its day.

Perhaps some newer tubes will make a difference in performance and maybe my expectations are too high. In any event,  the closing paragraph of Grammer's article may be more telling that I originally thought:

"The set as it stands is not perfect, of course; nothing ever is."

National Night Out was celebrated at Veteran's Park in South Plainfield, NJ last night. The police, fire department, rescue squad and office of emergency management were all there. And so was SPARC.



We had several setups going in order to be able to demonstrate to the community the various aspects of Amateur Radio - hobby aspects in addition to emergency communications aspects.

I had my KX3 going to the PAR which was held up by my Jackite pole. Dave Hackett KD2FSI had a VHF/UHF station going, as well as his JT65 setup going, and was successfully working DX stations. Dave also had his satellite antenna out for display.

I had the distinct pleasure of having three QSOs while people watched. The first was with Jim WB0ZWW in Anthony, KS.  Jim was using his KX3 so it was a 2X QRP KX3 QSO. But what made it special was that Jim just started using QRP power levels today - so I ended up being one of his first QRP QSOs.  Conditions on 20 Meters were decent and we had a close to a 1/2 hour rag chew.

The next QSO was with W8DIZ, Diz from Flying Pigs fame. Diz was using a QRPp rig, and I was his first NJ QSO. Hearing that, I lowered my power from 5 Watts to 1 Watt and got a good signal report back from Diz. Not having gone milliwatting in a long time, I lowered my power to 500 mW. Diz gave me a 449. Not bad for 1/2 Watt to an end fed antenna in a park, being lifted by a Jackite pole!

My last QSO was with John K3WWP. I explained to him what we were doing in the park and how he was helping me demonstrate Amateur Radio. John surprised me by telling me that today was the anniversary of the start of his QRP QSO a Day streak, and that I was his first QSO inaugurating the beginning of his 22nd year of the streak.  Wow - what an honor and a privilege.

Dave's satellite antenna came in handy later on in the evening as there was a very nice pass of the ISS. It was a good elevation - about 56 degrees and it came shortly after sunset, so the space station was very bright.  Dave aimed his satellite antenna and we were easily able to hear packets coming down from the ISS. That was cool!

But the capper of the evening was a landing by the NJ State Police NorthStar helicopter. This is the helicopter used for various NJ State Police activities, but is most famous as the premier NJ Medivac Helicopter.






All in all, it was a very pleasant evening, and I was proud to be able to represent the South Plainfield Amateur Radio Club once again.

By the way, according to the Reverse Beacon Network, this is where my signal was being heard:

Judy and I hiked to Bald Ledge in New Hampton today. We had a view to die for, and I worked some nice DX too… Spain, Bulgaria and the Czech Republic.

We started hiking at Sky Pond. It’s a crystal clear remote pond in the wilderness. It’s a favorite of local fishermen, but not known by many. From the pond we hiked a half mile up an old range road and then north on a woods trail for about a mile.

Bald Ledge is about 600 feet above the west shore of Lake Winona.

I tossed a 28 foot wire over a pine tree and sat down on the ledge facing northeast with the KX3. 20 meters had a few light signals. 15 meters was completely dead, so I started out on 17 meters where there were some strong signals.

EA5GX Sergio in Spain was calling CQ and we made a quick contact. There was some QSB, but he gave me a 579. It was nearly 15 minutes before I made a second contact. There were a couple of pileups, but I stayed away from them. Finally I heard LZ1GU in Bulgaria calling CQ. Harry was strong and he gave me a 569. “Are you happy?” Judy asked. “No….” I answered. “I need another QSO.”

Two nice QSOs and a perfect spot to spend an hour or so? Who wouldn’t be happy?

I like to get at least three contacts, so I scanned 20 meters again. There was Jiri… OK2RRR, the same station I had worked yesterday from Old Hill Village. He was booming in and I called him. Again he gave me 589. NOW I was happy! He told me he had received my email with the photos I sent him from yesterday, and he was pleased I was out hiking on a beautiful hill top. “Enjoy the hike,” he sent as he said 73 and wished me well.

Judy and I shared some fruit and I packed up for the walk back. When we reached Sky Pond, we both took our shoes off and waded in the water. Fantastic!

Like many of my projects, this transceiver is “on hold” due to my stroke. I am still too unwell to do much in the way of designing and building. One day, not too far away, I hope to complete this project. If anyone else wants to do this, please use my schematic as a starting point. With a small PCB it would make a nice club project.

It will make an ideal simple rig for nattering across town, especially as 10m loses its fizz and starts to act more like a vhf band again. Such conditions may be with us for years. I fancy putting this in a box like the old Heathkit Lunchboxes with a proper LS amp and LS.

Here is this week’s space weather and geophysical report, issued 2015 Aug 03 0155 UTC.

Highlights of Solar and Geomagnetic Activity 27 July – 02 August 2015

Solar activity was dominated by B-class flare activity (very low levels) throughout the majority of the summary period, however, Region 2390 (S17, L=199, class/area=Dai/170 on 27 Jul) produced a single C1 flare (low levels) at 01/2005 UTC, which was the largest event of the period. No Earth-directed coronal mass ejections (CMEs) were observed during the summary period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 31 Aug with moderate levels observed throughout the remainder of the summary period.

Geomagnetic field activity reached active levels on 27, 30-31 Jul and 02 Aug in response to an enhanced solar wind environment caused by the influence of multiple weak coronal hole high speed streams (CH HSSs). Geomagnetic field activity remained at quiet to unsettled levels throughout the remainder of the summary period.

Forecast of Solar and Geomagnetic Activity 03 August – 29 August 2015

Solar activity is expected to be at very low (B-class flare activity) to low levels (C-class flare activity) throughout the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate levels on 07-08, 17-21, 23, and 26-29 Aug in response to enhanced geomagnetic field activity cause by the influence of multiple recurrent coronal hole high speed streams (CH HSSs). High electron flux levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 28 Aug with active levels expected on 06-07, 17, 20, 26-27, and 29 Aug, all due to the influence of multiple recurrent CH HSSs. The geomagnetic field is expected to be at quiet to unsettled levels throughout the remainder of the outlook period.

It's been a few years since I've done any CW contesting, mainly because the laptop I have always used became slow and sluggish as well as developing a keying glitch when keying was done via the serial port connection. Apparently it is, or was, a fairly common problem with some operating systems when serial port keying was employed.

Last year I purchased and built the WinKeyer USB keyer, mainly to use as a USB keying interface, and hopefully kill the keying stutter. The stutter would manifest itself in the form of delayed element spacing. For example, the 'C' in a 'CQ' would sound like 'NN'- every once in awhile ... not every time, but often enough to drive me crazy. From lots of 'Googling', I learned that USB keying should solve the problem.

The first thing I did was to download and run 'CCleaner' to scrub the computer of unused files and clean up the registry. My contesting laptop uses Windows XP, which I've always liked but my old system was taking about eight minutes to boot-up from a cold start! Following the CCleaner run, I did a hard drive defragmentation, shut the system down, and pressed the 'on' button. This time the system booted completely in less than two minutes, the fastest in several years!

After, interfacing everything with a half-dozen clip leads (I didn't have the required cables), configuring the WinKeyer and setting up the N1MM logging software for this weekend's NA CW QSO Party, I cautiously waded into the fray.

Yikes!

Like riding a bicycle, it all came back to me quickly. The NA guys are hardcore CW fans and send fast, typically 30WPM or better. I started in the 'Search & Pounce' (S&P) mode to ease into the logging software's required keystrokes but soon felt comfortable enough to change to the 'Run' mode.

Handling the pileups and typing fast enough to keep up was challenging yet exhilarating ... it had been a few years since my last test, the 160m Stew Perry Contest, my favorite. I could only take the heat for so long and after about two hours of steady operating decided to call it a day. It was nice to shake out the new interface and also test my own skills once again. I completed my short test with 137 QSO's and 5891 points ... not much by 'NA' standards but still, for me, a ton of fun and a good 'back-in-the-saddle' re-start.

Now that the software is working well (there were zero keying glitches during the test), I'm looking forward to getting back into some CW contesting again and to improve my ear-brain-computer skills.

Time to get busy and build some interfacing cables and get rid of the clip-lead rat's nest for the next exercise.
