The MKV manual with regard to using an older and non-QSK amp such as 30L-1 are a little confusing to me. So: Can I directly connect the MKV to the 30L-1 from the Tx ground jack and setting the LIN switch to ON; OR do I need a relay buffer ala the FRB-757 or similar product to protect the MKV's switching relay? In advance thanks for any help. 73 de K6SBA David in Santa Barbara, CA
