[Heathkit] SB200

[sbjohnston at aol.com]

I believe the stock SB-200 has input tuning adjustments for each band.  
These will help you get a good match between the transceiver and the 
amp.  You should pick your favorite part of each band and set the 
adjustment for that band for minimum SWR to the transceiver.

Do you have the manual - the procedure should be shown in there.    If 
you need a copy I see that mods.dk site has it.

Hello. I have been following the list and i have a SB200 with 813`s . 
The amp
works very well. But when i transmit with the amp i have a mismatch 
between the
radio and amp. The rig is a TS850s. I have to hit the autotune to make
everything happy. The antenna is  1.3  match. Could the mismatch be 
caused by
the length of coax between the radio and amp? Could the problem be 
something in
the amp? or is this normal? Rick VE7RiK
