Re: U3S /5W PA on 2M
¿ªÔÆÌåÓýHi Ken,Not better, different. ?Thinking about easy access to VHF PA's rather than starting from scratch. Strip the driver & PA PCB's from a High Band Pye W15 Westminster PMR radio. Don't pay more than ?10 from a rally, unwanted & unloved because they are Xtal controlled RX / TX All modular, the PA RF design development done for me. Proper components, I'm biased it's my vintage. Also "free" in the sub ?10 price is a ready built low power exciter TX strip for a club fox hunt project courtesy of a ProgRock kit? And a full RX strip, pretty good front end compared to a current Yaesu Fusion repeater in a box, ask one of the repeater groups about real life "progress" when placed at a RF congested site.... If feeling nostalgic? get a bootmount Westminster W30, QQV06/40 bottle in the PA and you can hacksaw the HT inverter from the chassis so the power requirement is a 12v shack standard. There must be similar land mobile equipment available cheaply world wide to do something similar. Alan On 10/08/2018 12:19, KEN G4APB via

Yes, 0.5W is all I managed to achieve out of the '5 watt' PA. Was more 'acceptable' than the 20mW barefoot that I was getting before I added the PA. |
