Oh, long list.

I bought a Scout here in VK, from ebay "it was working fine the last time I used it" that took me a good couple of months to fix, from finals to a bent PTO shaft, from broken speaker to jammed s-meter... even the lamp was blown!. It is fixed now, and I added an RF-gain control (instead of mic gain) and I'm trying to figure out how to add control over the AGC time constant without having to drill holes.

I also have two Corsair II radios, I'm installing a panadapter. I'm struggling with the nearby AM broadcast stations as they get into the IF chain and there is no way to make them disappear form the waterfall. No good. They are great radios to play with, quiet receivers and plenty of space inside. Easy to fix.

Argonaut VI: this one had some digital noise you could hear on your headphones during quiet band conditions or when the RF gain was set a bit on the low side. Looking at the schematics, I found that there are two audio outputs out of the DSP board, one for the audio amplifier/speaker/headphones and another one for the DIN connector on the back. The audio at the DIN connector was absolutely free from digital artifacts, so I discarded the noisy DSP output and hooked the audio amplifier to the quiet one. Nicest radio ever. I started using it together with a 2m transverter for SSB, a Ten-Tec 1210 IIRC.

Argonaut V: this one needs new finals, they should arrive this week. In the meantime. I have been playing with an arduino that reads on which frequency the radio is in order to select an external low pass filter. I have been given an old CB amplifier (2 x 2SC2879, good bias circuit and an attenuator pad at the input) but I need to add switchable filters.

Hercules II: I just "segregated" the DC cable into three (two high current inputs for each RF pallet plus a low current input for control) so I can use two independent 40A power supplies. I haven't tried that yet, but it should work.

The list goes on, but those are the things that keep me busy at the moment. I love the brand.
