Started this project years ago but unfinished. Time to clear out the storage so free to a licensed ham radio operator is a partly built home designed 2 meter (144Mhz) amplifier in the approximately 1 KW CW (FM) or 2 KW SSB class. Based on a military (Navy) 150 Mhz AM transmitter made of heavy (A real understatement!) silver plated brass everything. Navy must have paid through the nose for this. I designed this as a 2 tube push pull single stage grid driven design using 2 4CX250 tubes or similar. The mechnical part is mostly built -- chassis, power supply and amp deck. Needs finish wiring and tuning. I may have some tubes for it. If not, they are cheap and readily available as surplus; lots of spare parts, maybe even another spare VHF and/or UHF deck if I recall ( for 432 MHz) but not sure, haven't dug through it. Technical advice gladly given if you need it. Whole box weighs maybe 70 pounds. I hate to scrap all these beautiful parts from US Naval history which could be converted to a very elegant showpiece amplifier. Would be nice for SSB or reduced power output FM maybe 800 watts (FM is a nasty duty cycle). I am willing to ship also at YOUR cost prepaid wherever in the world you'd want it. Tell a friend if you are not interested. Again, the amp is free, the shipping isn't. Free to pick up in San Bruno or meet me in Palo Alto at work to pick it up. Must be a licensed Ham Operator -- no flea market scavengers for this item please. Provide callsign on first email. Be prepared to show a copy of your ticket please. 73 from N6RF. Good in the call book.

I have a HF mini beam antenna I would like to give away, preferably to some young person. I took it down when I redid my roof.  It worked last time I used it and it has a manual. I am in Mill Valley.
