Hi Folks, I could use your help! I'm in the process of re-kitting a Valiant I transmitter using the Valiant Assembly Manual. The Valiant wiring harness schematic in the Valiant Operating Manual shows blue wire 71 entering the harness at breakout K and coming out at breakout Q. Breakout K is between the modulator tube sockets (XV16 & XV17), and breakout Q is at the RF output SO-239. I have looked over all the steps in the assembly manual multiple times, and I can't find any references to 71A or 71B. Could you check your resources and tell me if you see any references to this wire? Considering that it is the last numbered wire in the harness, I wonder if it was put there for some purpose, and then never used, or maybe it was originally used for some purpose which was then deleted. I'm really puzzled! Like I said, I've been through every assembly step in the book, and there are NO references to wire 71! Thanks for your help! Mike, WB0LDJ mharmon at att dot net

Is there any info on programming software and cable

I'm in need of one of the Buffer or Final tuning knobs with the 0-100 scale for the Ranger or Navigator. Anyone have a spare they'd part with? 73, Floyd - K8AC

I’m about to begin modifying my Viking 2 for operation with the 6N2. The modifications on the Viking 2 seem straight forward with the exception of two things. Thing 1: changing out the VFO socket on the Viking 2 to a 9 pin socket and “socket support shell”. I’m not following what a “socket support shell” is unless it’s the mounting bracket for the socket that connects it to the chassis. I’m unable to find a 9 pin socket so I planned to simply use the existing ceramic 8 pin socket. Pin 9 on the 6N2 is a ground and there appears to be several unused pins on both the V2 and the 6N2. I’ll just use pin 8 for a ground and replace the existing 6N2 9 pin male connector to a 8 pin male. I’ve got plenty of 8 pin male and female connectors and shields. Thing 2: I don’t see anywhere in the 6N2 manual providing these instructions to modify the Viking 1 and 2 or the Ranger that the modifications will allow normal operations of this equipment after they are modified to work with the 6N2. If it’s necessary to reverse these modifications to operate my gear on HF, I may look for another way to supply and modulate my 6N2. I’ll put a sticker on the Viking 2 VFO socket stating that plugging a 122 VFO into this socket might not be a real good idea. Thanks, Tom N5AMA

Does anyone have any experience mating a 6N2 with the Clegg Thor supply/modulator? I’m trying to put a 6N2 on 6m AM for some local rag chewing and really not interested in modifying either of my Viking 1 or 2 transmitters to work with the 6N2. I think I should be able to cobble up a cable between the two if it makes sense. I would go with the Thor transmitter and supply but can’t locate a Thor transmitter. Any help appreciated. Tom N5AMA

For Sale: Johnson Viking Valiant 1 This radio is in good overall shape and appears to be complete. It is untested. Condition is commensurate with age with some “patina”, especially on the rear panel. All knobs move easily. It has been in dry storage for 10+ years. There appears to be extra switch on the front panel placed there by the prior owner. Additionally, there appears to be one 6-pin tube missing, and another was replaced by what appears to be an R/C network. Because of the above, the radio is being sold for “parts-only”, although I believe that it would be a very good base for a high-fidelity AM transmitter. Asking $75.00, pick-up or meet-up in Metro-west Boston. Other delivery and meet -up arrangements are possible. I would like to see it go to a good home. 73, Gene K1NR

Hi Folks, I don't expect any of you to waste a lot of brain cells on this idea, but I thought I'd run it by you to see if you experts might have an idea for me to try: I'm rebuilding a Johnson Valiant I, and after it's complete, I plan to use it on the 160, 80 and 40 meter bands as an AM/CW station along with my Collins R-388 (51J-3) receiver. I've never been a fan of Dow-Key relays as a means of switching antennas from transmit mode to receive mode. Ever since I was a novice back in the Sixties, I've always liked using an electronic TR switch. Break-in CW used to be sort of fun back then, and there's no clacking of relays on voice modes. The problem with most TR switch designs is the lack of receiver muting capability. The best TR switch ever built was the Johnson 250-39, and I have 3 of them! They work like a dream for T/R switching, but there's no way to mute the receiver during transmit. The R-388 just happens to have a terminal strip on the back that is connected to a 12 VDC T/R relay inside the receiver. When closed, the relay shorts out the front end and kills the B+ to the later stages to mute the receiver. This relay could easily be changed to a faster, quieter relay if needed. The challenge is - how to activate the relay? Now my brainstorm .... The TR switch uses the RF signal to grid-block a 6BL7 dual triode during transmit, and as soon as the transmit signal goes away, the 6BL7 reverts to being a common cathode RF amp. Is there any way to use the grid current in the tube to drive a FET or something similar, which could then be used to activate the break-in relay in the receiver? I've mulled this idea around for a while, and run it by some local guys, who mostly just did an eye-roll and told me to just use a Dow-Key and put up with the howls from the receiver. Well, that's a possibility on CW, but certainly not on voice. Am I crazy? Deluded? A wishful thinker? I know the technology is there - I just don't know how to use it! I don't know how to attach a PDF of the TR switch schematic, but most of you probably have it anyway. Please tell me what you think. Thanks! Mike, WB0LDJ mharmon at att dot net

I have a Viking I transmitter. Anyone know of any videos that sow how to bring it on line a transmit. It is not as straight forward as today's amateur gear and I am having trouble finding anyone who can walk me though the process.

Hello everyone ! I have recently acquired in a box of mostly Tektronix manuals (for which I’m also looking for a home) a Johnson Viking I transmitter manual. It even has the un-numbered page with instructions about how to connect the transmitter to drive “a larger modulator” – a page Johnson inserted between pages 8 and 9. It's clearly mimeographed, and the pages are light tan, no longer white. The cover has a picture of the transmitter and the typical Johnson red-orange bands across the top and bottom. It says that it’s CATALOG 705, but the insides are clearly a manual. Only the top two pages, which are printed on glossy stock, appear to be from a/the catalog, so someone apparently stapled the relevant two pages from the catalog onto and as the front pages of the aging mimeographed Viking I manual. It also has a page of handwritten notes about how to tune up the transmitter. I don’t have a Viking I – I have a Valiant and a Navigator, so I don’t need this manual. So, it’s free to a good home. If you have a Viking I and would like this manual, please let me know and I’ll send it to you. First responder gets it. No cost – I just can’t bear to throw away equipment manuals! Now if you know someone who’d like a cardboard file box full to Tektronix manuals, please tell me. I’m trying to keep them out of the landfill, too!

Hello Group, For sale are a Johnson Thunderbolt and a Johnson Pacemaker. Both are in excellent, uncorroded or rusted, condition. Collector quality, except for scratches on the top outer cabinets. Nothing that can't be touched up. They are just too heavy for me to deal with. Both for $800. Prefer not to separate. Shipping would be extremely expensive and detrimental to the equipment, so pick up is required. Located in the South Bay, 6 miles south of LAX. Can be delivered within 20 mile radius.

What are the recommended microphones to use with a Ranger II for best audio? Thank you. 73, Michael Smith, N4KZO -- 73, Michael Smith, N4KZO
