Maybe I can find a deal on an Argonaut at Dayton this year. Will give me something to look for. Yuma Hamfest is next weekend
I'm catching a ride with another ham on Saturday morning. I'll keep an eye out for you, Pat.Quote:

The repair itself is relatively easy... replace them... although getting the heat sink out of the way is a minor pain.
You can also find a lot of info about the older Argonauts (505, 509 & 515) on VE3AB's web site (*). Earl had a lot of nice articles about restoring them as well, and he was looking into new circuit boards that would replace some of the older ones that have been... for lack of a better term, let's say hacked up by previous owners/repairers. Earl also was working on a new final PA board that would be a direct drop-in replacement for the 515, and would bring the 505 & 509 up to the 515's power out (7 to 8 W out as oppsed to 2 to 3 W out)
It's a nice little rig.
What I should do is make a decision on the Argonaut V that I got from W3WH. It's only putting out about 5 W, not 20. (Ten Tec said it had lightning damage and is unrepairable). On the one hand, I ought to troubleshoot it, and down the road at some point I will. On the other hand, if I leave it 'as is' then I can use it to drive my 1208 6 meter transverter, plus run it on HF for PSK 31. We'll see.

I figured it was something like that. Yes. Whenver you get a round tuit.Quote:

Those old Argonauts work very well, and surprise folks that are used to new radios.
20m for me. When I was first licensed 6m was a blast when it was open.
The year after I got my Advanced license I got hold of an HA-460...dipole at 20 feet...and managed to work the Caribbean during an opening. Still have all that in the log.Quote:
