Thanks for the memories. Used to design these things for the military market, but then I got a brain tumor, so part of my life has left me. Guys like you and your videos brings back memories of the old days, and I like to follow it, and get some glimpses of the stuff that looks vaguely familiar. Wish I could get back into the design-field, but that train has left the station… now I enjoy videos like these. 👍👍👍👍
Those pots would benefit from being replaced, and also with adding in some resistors to limit the operation range as well. Or you can replace them with 10 turn preset pots, and have the benefit of less track noise as well. Icom should have put a resistor in series with the ends of the pots, to reduce the available range they can adjust to something like 2V to 5V, which would make adjustment much easier to do, as the circuit says the range is around 3V. 1k each side of the 2 pots would work well enough, making it less critical, and reducing the effect of the noisy pots and drifting as well.

10 watts might make a nice FT8 rig. Nice series, thanks for the tour through the radio.

"It's an old radio." I still can't think of a solid-state radio as being "old!" :)
Good day! Excellent as always! Great! Best regards from Russia
Yer I reckon it was the new caps. Welldone
Same device as the AN612 I believe and the datasheets are a little more readable.
LSB looked to have lower output than USB....
Hi there. Thanks for these videos. Would you be willing to give a fellow ham some guidance with an interface project? VA4SMC.
