[Heathkit] SB200

[Rick Gouge]

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
