Hi All, I haven't been paying much attention to the conversation here about keying amps, etc. since I rarely use one. However, a situation has arisen which suggests I should have paid closer attention.
I have a couple of small amps--an HL50B, and an HLA-150, that work well with QRP rigs for a little extra boost. The HL50B works best with the K2 (and other QRP rigs) as it has good RF sensing, and keys right up when you hit the paddle. The HLA-150, however, doesn't do quite as well. It supposedly has RF sensing too, as well as auto band switching, but on CW I find that it is just a tad slow in triggering. Accordingly, it tends to cut off the first "dit" or "dah". That's about the only complaint I have about it though. With less than 10 watts of drive you can get over 100 watts out. The auto bandswitching works very well. The HL-50B puts out about 60 watts with 5 watts of drive. The HLA-150 has a keying line input jack for direct connection to a transceiver. However, the K2 doesn't have a keying line output that I'm aware of. So, my question to you amp gurus is what would be the best (easiest) way to make this work? I'd take my HL-50B, but I left it up in Oregon with my motorhome. I'll rectify that mistake the next time I get up to Oregon. Any suggestions?
