Title: Kenwood AM Post by: k6ddx on March 10, 2019, 01:40:25 PM I suspect this has been addressed before, but has anyone devised a simple modification to the TS-520 or the TS-820S to make it work on AM?
I suspect the kicker is my use of the word 'simple'. Those are terrific radios, reliable and great performers, still in wide use today and available at low prices. Title: Re: Kenwood AM Post by: KK4YY on March 10, 2019, 06:57:06 PM Simple? Okay, get out your screwdriver...
On the TS-520, adjust the carrier balance pot, VR3 on the Generator unit. On the TS-820, it's VR5 on the IF unit. This will produce single sideband AM. This is as simple as it gets, but I don't actually recommend it. If you want to do the AM mode justice with those rigs, you'll need to move past 'simple'.

Disabling the balanced modulator (or at least preventing carrier removal) and bypassing the sideband filter is what it would take. However, Pandora lurks and I suspect some of the rig's performance would be compromised in important ways. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
