I've repaired several knobs this way, and I now do it as preventative maintenance on all my Ten-Tec knobs. See the description (sorry, no photos yet) on my website at http://k9ew.us/knob_repair.htm.
Hi Wally, Take a look at my website (www.k9ew.us) under Projects / Argonaut 515 PTO. The 509 and 515 are very similar, and I've documented the disassembly / assembly process for getting to the PTO. G
Hi Mike, Maybe the heterodyne oscillator for 80m has low output, or it may be far enough off frequency to be attenuated by the 80m filtering. If possible, follow the RF from the PTO through the mixer
Hi Bill, I also have a spur near 21.320, so I'd guess it's normal. Rebuilding the PTO is actually pretty easy. Getting it out is usually the hardest part because it's different for every radio. It so
Hi Roger, If you really want a good filter for the Triton, take a look at "Add a Crystal Filter to Your Ten-Tec 540", appearing in the Sep 1981 issue of QST on page 16. I made one up for my Argonaut
Hi Gary, Have you confirmed that the source of the problem is from the particular AC power line hookup you have? I've been reading the Power Line thread with interest, but don't recall a direct confi
Thanks for posting this information, JT. I'm sure the question will come around again. And now we know the answer. 73, ed - k9ew www.k9ew.us _______________________________________________ TenTec mai
Hi Mike, What's this email about? ed - k9ew _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
Hi Gil, Yes, the T/R switching line in the 509 really wants to see a good solid ground for proper operation. I've had to try various keyer output transistors to get decent operation. No problem with
Hi Gary, This sounds like a *real* project radio. But all the 509 owners on the list will be interested in your progress, so check in whenever you have an update. 73/73, ed - k9ew www.k9ew.us _______
Maybe someone in this Group has had to paint a 509 front panel, and can offer some suggestions. 73, ed - k9ew _______________________________________________ TenTec mailing list TenTec@contesting.com
My preference is to look on eHam.com, QTH.com, QRZ.com, and the various lists available on QTH.net. I have found these people more interested in finding a good home for their radios, than making as m
I agree that the rebuild of the PTO is very straightforward. You can find good instructions at W5ESE's website. I also agree that figuring out how to remove it from the rig is the hardest part. I doc
Hi Dave, A good source of an accurate frequency counter is your local hamfests. I've seen (and bought) HP-5382A frequency counters for $30. If you can find one with an "Option 1", that has a high sta
Thanks for the idea, Scott. Never gave the old Argosy a thought for a DDS, but now it's high on the list - it could use it more than the Corsair II. Might be in touch once I get into the project. 73,
Hi again Scott, A question just popped into my mind... what did you do for the display? tnx es 73, ed - k9ew _______________________________________________ TenTec mailing list TenTec@contesting.com
Hi John, Wouldn't it be worth a call to Ten Tec to get the information directly from them? 73, ed - k9ew _______________________________________________ TenTec mailing list TenTec@contesting.com http
If you can't track it down from the other suggestions, try keying the TX with a straight key connected to the key jack. I found a keying problem on another Ten-Tec rig than needed a really solid grou
Hi Denton, If you're operating at home, you could use the *Expandable Headphone Mixer*from the ARRL Handbook in the Station Setup and Accessory Projects section (Section 22 in my Handbook). You could
