-Finding an affordable single-band FM radio for 6m is a challenge, occasionally these Alincos turn up on eBay so I nabbed one tried my hand at modifying it. As it turns out they're well built, old-skool analogue architecture and a breeze to work on. The service manual is widely available online and is superb.

 The PA puts out ~20W and can be adjusted using VR1. The deviation is adjusted with VR2 and is set ~5KHz from the factory. On receive it's (apparently) very selective & sensitive, and the second IF filter is 20KHz wide so this TRX might even work on wider bandwidth modes. Using an IC-705 as a reference receiver the wideband PLL phase noise looks to be very low and there are no horrendous key-up transients a-la FT-1500M.
