Hi all, Here is what is taking up desk space:* Ameritron AL-80B*. I moved from Liberty county a few years back into an HOA. I just don't have the antenna's to warrant that kind of power here. It has had very little actual use. I've been turning it on occasionally to power up the caps, etc. and to check high voltage. Tested last week and it seems to be working as it should.
Bought new: always non-smoking home. I am asking $1800.00 (pick up in the Humble area) and will include the MFJ - 998 "IntelliTuner" for that price. I have the box and manuals. If interested: Rick Fosburgh KE5DI email: rickf...@gmail.com Thanks, to all! Rick On Thu, Aug 17, 2023 at 12:23 PM Mike Hardwick <n5...@att.net> wrote: > Go for it.
