Sweep tube amplifier question
30 Dec 2017 19:21 #2631
I am wondering why it is that my Icom 706llg goes into swr foldback when I trigger this little sweep tube amplifier? I can't understand why the radio would suddenly see an rf reflection like that, unless the relay wasn't working properly. Something to do with not having a tuned input (I don't know this as fact; just read it somewhere)? I ask this only because I do not have any experience with tube amplifiers, sweep or otherwise. I understand the Dentron GLA1000 isn't the best amp out of the box, but the price was right (free is a very good price) and I would like to eventually do the GI7B mod to it. The amp worked fine at the last owners qth, so why is the 706 being finicky? This is a learning experience for me and I know I must be missing something glaringly obvious, so have some fun at my expense - please!
I didn't find the right solution from the Internet.
