Hi Doc, There's a small 4-pin accessory socket on the back apron of your 515. Without the 208A filter, you just insert a jumper plug that routes the audio back into the radio. With the 208A filter, r
Hello Mats, I just did a check on my 509, and I can adjust the RF Output power to all power levels you mention - by adjusting the Drive control. What you might need is a power meter that can measure
Don't forget that an attenuator will also be in the line for the Receive mode. A few db won't be noticeable, but 10db might be. 72/73, ed - k9ew _______________________________________________ TenTec
Hi Giorgio, I have a couple of questions... 1) Have you called TenTec? They may be able to give you a very short list of things to check. 2) Does your PTO tune smoothly? 3) When you tune in a signal,
It's starting to sound like a mechanical problem with the PTO tuning as Jerry described earlier, and a rebuild may fix it. It's not expensive or difficult to do; it just takes some time. That's what
Also take a look at some pictures of the "inner" front panel and dial cord on my website at www.k9ew.net, under Projects, 525 PTO. You're right; the hardest part is getting started. Hope this helps.
The Allen wrenches are 0.050" and 0.060". I'll bet TenTec has them. 73, ed - k9ew _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com
Thanks for the information, Jerry. If something like that occurs in the future, I'll be prepared. These lists are a great source of that kind of information, and I appreciate that you shared your fin
I removed and rebuilt the PTO in my Argosy, and the hardest part was figuring out how to remove the PTO. So I documented the process (with photos) for myself, and anyone else who might need it. It's
Do a Google search for "Triton IV modifications", "Argonaut 515 modifications", and "Argonaut 509 modifications". Also, "TenTec modifications" should give you plenty of information. You could also s
Hi Steve, I don't think I've ever heard of 75 ohm twinlead. I looked up 450 ohm twinlead on www.thewireman.com, and the vf is 0.91. For 300 ohm twinlead, it's 0.66 for solid dielectric, and 0.91 for
Look in the instructions for the PTO Assembly. Step #2 describes how to disengage an idler gear that connects the PTO shaft to the frequency dial. 73, ed - k9ew ______________________________________

Hi Mark, I just checked my 525 (analog), and the receive noise level is the same in either position. 73, ed - k9ew _______________________________________________ TenTec mailing list TenTec@contestin
Hi Tod, Google has free websites that you can create. Go to googlepages.com for more information. 73, ed - k9ew _______________________________________________ TenTec mailing list TenTec@contesting.c
This is a long shot, Reed, but maybe it's sticking because of static electricity. Try wiping the meter with a damp cloth. If static is the problem, this would prevent the "sticking". A longer term s
Hi Gary, There's an easy-to-build wattmeter that's pretty accurate that I've been using for years. It was designed by Roy Lewallen, W7EL, and the article appears in Feb 1990 QST. You might find it o
Again, no, but there is a program that will remember the settings so you only have to do it once. I have been using Romac's "Sound Card Management" program, available free from www.romacsoftware.com.
Yes, same idea, but much smaller, less expensive, and battery operated. You can make your own enclosure, and paddles if you want, or you can buy them prefabricated.. I bought mine from CW Touchkeyer
Hi JT, I know I can't do it on my Argosy because of the frequency drift. So I would think any of the frequncy synthesized Ten Tecs would be about as far back as you could go. This does not include di
