Question for the group
5
Hello We recently came across a collection of Military Manuals for test equipment, earliest date is 1946, latest is the late 50's. About 10 original military manuals in all. Various types: A couple of oscilloscopes, analog meters, etc... All are OEM military manuals in pretty good shape. Will make very fine copies.. Question: We would like to make copies available to people who are looking for this sort of manual, Is there a IO group that specializes in these 40's and 50's military test equipment things ? We would copy the manuals and make them available for copy cost and media mail to the US Lower 48. Thank You very much Ashley Thank You Kiss-Electronics Ms Ashley Hall 183 N 5th PL.

Viking Challenger Kit - Unassembled in Box
I bought this Viking Challenger kit about 5 years ago. The top flap had been torn off but it looks like the contentsd have never been taken out. It's packed so tighlty I doubt I could remove everything for a contents display and be able to repack it same way.. I would enjoy going through the assembly but I have a Viking 500 that will keep me busy for quite some time plus I have several home-brew projects that need to get finished. I paid $475 for it and I'm not trying to make any money. If there is a serious buyer I would take the risk of videoing my taking the contents out of the box. Although I am new to this group, I have been an active member of the Collins group and can provide many references. Local pickup always preferred. Jerry NY2KW

Johnson Viking Matchbox Modifications
Joe, I have modified both my 275W and KW matchboxes. Here's the changes: 1) Remove the T/R relay and wire straight through. 2) Add two ceramic feedthrus to add capacitance to the main tuning cap for 160M reasonance. 3) Disconnect the link coupling coil from ground and the input. Add a four position ceramic switch and tap the link in four places. Add a 350pF variable capacitor in series between ground and the cold end of the link coil. Feed the RF into the matchbox via a So-239 with the center pin going to the link coil tap switch. The changes allow the Matchbox to achieve a near-perfect match (SWR1.1:1) on most any antenna. I use the KW matchbox with a full-wave delta loop fed with 450Z open-wire line matched to a Globe King 500A running about 300W on AM. Works great. I use the smaller matchbox only for Field Day so I placed the link controls on the rear panel. Very easy modification. However, the KW Matchbox was not so easy. I wanted the link switch and cap on the front panel for ease of use. The most difficult part of that modification was creating a shelf in the KW matchbox on the upper right side for the link switch and capacitor, and getting the faceplate holes lined up. But, the job turned out to be a nice looking and functional tuner. Attached are a couple of documents that outline the details. 73 Bill N4LG At 11:27 AM 1/10/2025, Joe WB9SBD via groups.io wrote: >These are awesome Matchboxes! > >I wonder if anyone has ever modded one by taking >the tapped bandswitch, out, or installed a more tapped one, >so the inductor is even more variable, so the >matching ranges can be even wider!

I recently acquired what appears to possibly be a control box for a Johnson Matchstick Multi-band Vertical Antenna system. A number of internet searches provided a few images on ebay and several auction houses but no meaningful information, instructions, manual, references to or about it. Accordingly, I am reaching to the group for help and have attached three (3) images for reference. If anyone has information, instructions, references, etc. and would share it with me I would appreciate it. Tnx es 73. John N7NWL

WTB: Power Supply/Modulator for Viking 500

Good day folks. I just obtained a Viking 500 RF deck that over time was separated from its power supply/modulator unit. It is a long shot, I know, but this group is probably my best chance in finding one. Even an incomplete unit will be considered. I guarantee I will bring it back to life. Thank you.

Transcrypt Transpeater III
I used to have a copy of the specs and user guide of the Transcrypt Transpeater III but I no longer have it. We used them in the fire service back in the day. Does anyone have an idea where I might be able to find some information on this particular piece of equipment? I spend hours on archive.org and there is some old archives of the websites but no product. I'm searching for anything relating to it, anywhere from an electronics diagram to the piece of equipment itself.

Tekkie Note: Johnson Valiant I & II
Hello One of my guys wanted me to post this tekkie note concerning the Johnson Valiant I & II, modulation transformer wiring issues. What we found in our rebuilds of Johnson Valiant I&II was , often, the terminal strip material which supports the primary and secondary wiring leads from the modulation transformer has carbonized ( most likely from heat), the terminal strip insulating material between the terminals becomes conductive and the modulation transformer goes up in smoke. What WE did was to create a custom double spaced terminal strip, using parts from those really nice strips that are used in Johnson radios. The double spacing reduces the chances of inter-terminal carbonizing, current flow and subsequent modulation transformer meltdown. We checked, carefully, the material ( phenolic ?) to ensure there were no signs of carbonizing before creating the double spaced strip. Our $02 worth.
