I went to try my first CW contact last night on the Argonaut 505 that I bought recently and when I measured the power output, I was surprised at just how low it was. I measured 2.5 V across the diode
Hey Neil, when you say that you, "went to try your first CW contact.." does that mean you have made SSB contacts with the Argonaut? In other words is the power output the same rather low number in bo
No, no SSB contacts on this rig either. I don't even have a mic wired up for this radio. Instead, I meant that I went to make my first CW contact ever in my life. It was at least nice to have the sid
Neil, The Argonaut 505 did not have a broadband driver. It has a tuned circuit that is also tuned by the elevator/pre-selector control - the top left knob. You have to tune it for maximum during tran

The elevator is aligned properly so that both receive and transmit peak at the same point. Thanks to everyone for the other troubleshooting tips. The problem turned out to be much more prosaic: low p
This is not at all meant to be critical of Neil and his power supply utilization, but more in reference to past comments about switching power supplies. Frankly, I view things such as this which most
I wouldn't dream of using a switching power supply on an old Argonaut. It needs only 1A key down, so the smallest linear supply you can buy or build will work. Although there are plenty of clean 30A
Radio Shack used to sell a really nice little 1 amp regulator linear supply. I am fortunate to have purchased a couple way back. It is hard to find that sort of thing these days, but I see them now a
Rick you are almost certainly right about the wall warts. That may be why some of us are watching our S-meters dangle around S4 - S6 a lot of the time these days. It's annoying, but that's the way it
