Re: WTB Johnson Signal Sentry
You might also try the Johnson list at the mailman.qth mailing list.
It will get more eyes on your request. Neither group is very active but they're not dead, either.

Re: building an external power supply for VFO 122.. now remote VFO enclosed in new case with added features
Terry took a VFO (likely from a Ranger) and made IT external as a utility VFO for various EFJ gear etc...his improved VF0 122 he calls the VFO 123.
External... 3 videos (this time you get the URLs... HI). Sort of redundant.. the later recent (August 2022) video on the external PS for VFO 122 or a VF1 just serves the purpose of addressing use of VFO 122 for Heath or EFJ...where the rig PS is lacking/weak (Heath) or to overcome drifting via warm-up state. Of course the drifting is solved by A - the operator moving his VFO when he spots and notices he is not where the receiver is or B) the operator on the OTHER side of the QSO moves his receiver (RIT) to 'new frequency' or lacking RIT adjusts his receiver (aka tuning)... and we all merrily move around the original frequency....

Re: building an external power supply for VFO 122.. well actually just restoring existing power supply
I had to search to find the video you referenced. I found it here:
I subscribe to Terry's Patreon also. I highly recommend supporting him. He loves the EF Johnsons and does much to keep these rigs safe and on the air. I had not thought about having a separate PS for the VFO-122. To me, it lives with the Viking II that I also need to get going and get on the air. It is getting PTT installed this week. -- Dennis NS8H |

building an external power supply for VFO 122.. well actually just restoring existing power supply
Just to have something new to say here....
I was watching a video on the D Lab YouTube channel in which Terry Dayton shows building a simple power supply to power a Viking 122 or Heath VF-1. After thinking about it and where I would get transformers and choke... I remembered I had some Heath utility power supplies from hamfests (such as for HW-101). I knew I sold one of them at? one of the last hamfests before the Pandemic.. but still had a couple left (got them cheap, left over from the Institute for the Blind old radios when the equipment was retired). I assume are seen at hamfests.... Anyhow, there were various models of the PS23... later ones don't suit. I have one that is later which is not suitable... but the version A I do have as well will do the trick nicely But early ones DO offer selectable 250/300 volts and 6.3 for filaments... later versions are 12 volt filament. So... for the cost of some capacitors and about 7 diodes and a few resistors I SHOULD have a p.s. that can power my VFO 122 - keep it warmed up and less drifty? before the transmitter is turned on. This is a warm-up project before I tackle one of the two Viking II xmtrs I acquired during the Pandemic.... I am not quite ready to tackle them yet.. post-surgery here so lifting 80 lbs. is not yet in the cards... but I will get one on the bench and ready to work on before I have to endure any follow up medical stuff. Hoping to see the Viking II on the air by late Autumn. I have other EFJ gear (in line for attention!) that I can use the external p.s. supplied 122 on as well (Challenger, Adventurer, Navigator).? Anyhow, I thought I would throw this out there into the ether in case there was interest piqued and anyone is wandering a hamfest wondering what might be useful. And...I can use it (different pin out on the octal cable of course) on my Heath VF-1 once I finally get to the DX-40? rig restoration (do I really have two of them ?... not sure what lurks under my staircase sad to say....). A good idea for the Heath VFO-1 since the small rigs have pretty persnickity power offerings and borderline at that I believe. 73 Brian VE3HI? ?Toronto ON |

Ignition Sense Settings 5300 ES and 53SL ES
Hello All,
I hope that you are well. I am programming some 5300 ES and 53SL ES mobiles using PC Configure 2.18.16. I am looking for the setting where one can choose if the radio needs to be connected to a powered ignition cable to turn on or if the radio can be turned on via the front panel with NO powered ignition cable connected. It looks like a powered ignition cable is needed at all times to turn the radio on. Am I missing something in the programming software that would allow the radio to be turned on with NO powered ignition cable connected to the radio. Thanks for your help and support. All The Best & 73's (too) Charlie |

Re: Hello
I have the VFO-122 for the Viking II transmitter. The Viking II had beautiful workmanship done on the caps and other replacements with quality parts and work. The VFO had the Chernobyl Resistor changed out, and that beast is ready to go on the air. The NC-300 needs to have the dial cord restrung. The rotating display does not flip, so I need to get that done. There was nice work done on the NC-300, and I think it will be ready to go soon also. I still need an adjustable dow key to get the pair working together, along with rearranging my desk to figure out the optimal placement of this AM pair and my Kenwood Hybrids (TS-520s, TS-530s), Heathkit Cantenna, and a Palstar AT1500CV tuner. I need some shelves and height for sure. 73 - Dennis -- Dennis NS8H |

Re: Hello
开云体育Hi John, Yes, the Viking II came from you!!!? I really got going on it soon after getting it from you.? Then my dog had a running start on a 30 foot retractable leach.? I wound up with a broken hip. That happened February 9th of this year.? I was in one hospital after another for three months and wound up with plenty of complications.? I got kind of finally back to normal in June, so now I have plenty of catching up to do with my radio projects as well as building a home for one of my daughters.? The front panel of the Viking II is all masked off ready for painting.? That switch hole is totally gone on the front panel.? Once I air brush the paint with the paint I had matched for it, you will never be able to tell the hole was ever there.? Same for the cabinet.? I had paint mixed for it too.? Indeed when finished, I'll send you pictures.? You will never recognize it.? I changed out some caps and replaced the audio driver transformer plus checked the tubes and replaced those that were missing.? Your Viking II will be a real show piece when finished.? Hope that will be soon and on the air.? (I picked up a Heathit VF-1 VFO for it and plan to use the VFO plus crystals when on the air.? Hope all is well with you. Lee, w0vt Coldspring, Texas

Welcome, Leland. I would love to find a 500 and matching

Re: Hello
开云体育Dick, Collins did a lot of pioneer work and got a lot of money from the military to fund their designs.? Their S-line products were a wonder mechanical looks and design.? I don't think their electrical circuits were as good as RL Drake's who did amazing things with his TR-4 designs. ? Maybe Collins electronics were more robust, but for electrical design, Drake had a 500 khz PTO and not 200 khz as Collins.? I think Drake also had a much better AGC circuit then a Collins.? In fact, I think the Collins AGC circuit was kind of poor.? All that said and done, Collins gear looks beautiful.? Back in the late 60s, an engineer friend of mine sneered at Drake gear.? He said, "Drake uses slide switches and their coil forms are cardboard."? Here we are 50-60 years later and the slide switches still work and the paper coil forms still work just fine.? Drake was a master of using low cost products to make first class working gear.? Heathkit stole a lot of designs from Johnson and made a big bang for your buck transmitter when they came out with their DX-100 transmitter.? Out of all the Novice transmitters sold, the DX-60 was also a lot of rig for the money.? It was hard to beat for being a low end transmitter. The DX-60, Drake 2NT and Eico 720 Novice transmitters, to me, were the best of the Novice breed of transmitter. Lee, w0vt

Reminds me of what we used to say back in the day ...
"If you want to know what frequency they are on, buy a Collins,
if you want to hear them, buy a National"
I had the NC-303 back in the 60's, great receiver. The NC-300
was better on AM though.

Re: Hello
开云体育Dennis, I Heathkit VF-1 makes a nice fairly inexpensive VFO for the
Viking II.? You can get power off the transmitter or build up an
outboard power supply for it.? I always like to use a separate
power supply even if the transmitter has plenty of reserve for
one.? That way you can fire the VFO up without turning the
transmitter on.? This might help stability too.? Around Texas,
there is a lot of AM activity on 7130 khz.? I've been off the air
for some time but plan to get back on with the Viking 500, Viking
II and the NC-303.?? (I have an SX-71 I've worked on and off for a
long time.? I had to replace almost all the resistors which is
around 100 of them as they were out of tolerance.? Plus had to
replace electrolytics and paper caps.? I've always loved the looks
of the SX-71 as I drooled wanting one as a grade school kid.? Back
in the 50s when I was first licensed.? The Viking II and SX-71
combination was extremely popular.? I worked a lot of hams with
that combination. Lee, w0vt
