Hello all First let me say how much I have enjoyed the recent discussion on linear amplifiers. I have a Kenwood TS-820 that I would like to modify for am for a standby transmitter. A day or two ago I remember seeing a remark about modifying a TS 820 for double sideband. I have a friend who has a 520 and used screen grid modulation for am operation. The email containing the remark seems to have been deleted. Any remarks or where to get the information would be appreciated.

that was John/WA5BXO and he said:
I suppose it is also preference. BJ and I modified the Kenwood TS820 to full double sideband and it runs about 10-20 watts carrier output in that mode we drive and SB200 modified with a switch to kick in extra bias when we use in on AM. It puts out about 75-80 watts carrier with good modulation characteristics. So the combo is equivalent to a DX100 with maybe better audio.
As to HOW he did it, you'll have to ask him. -- 73 = Best Regards, -Geoff/W5OMR
