I'm thinking about getting an HF amp. Found a good deal on a used Kenwood TL-922A in good working condition. Before I buy it I want to be sure it will interface with my FLEX6300. Are you using one with yours? Did you hookup the ALC cable too? The Flex documentation doesn't recommend that.
Dave, do not hook up the PTT output of your 6300 to the Tl922A! Doing so will destroy the keying transistor in the 6300.
The 922 has 100 VDC on its key line input. You will need a hardware interface between the 6300 and the amp PTT input. Ameritron makes an interface or you could make your own with a small 12 volt relay.
No need to hook up the ALC with a Flex, just don't overdrive the amp.
I agree with all of that. I had a 922A for a couple of years and used it with my 5000 and 6300. It served me well. If I remember, I paid around $900 for it about four years ago. Now, if you're getting a real good deal, go for it.
However, I can't say enough in praise of the Elecraft KPA500 when used with a Flex. If you couple it with a KAT500 tuner, it's like having a 500-watt transceiver. Virtually no tuning required.
I worked a lot of DX and busted through a few pileups with my 922A. It's a solid amp. I finally parted mine out when the capacitors got too old and failed.
reading the above ..i am concerned.
i run a.922 with my flex 3000.
am i in the same boat as the 6300?
i am using a heavy duty rca type lead from flex to 922 with no trigger issues.
i need to know if im good or if i should be concerned.
