Power supply stability. Built cheep, get worse with time, insufficient heat dissipation due to endless complaints about fan noise, cut corners on components, too small wire to rig, yada, yada, ad nauseum. Power supply issues can cause rig overheating, spikes, slow power build up, unstable power output, audio distortion, hum, frequency drift, broad signals, even key clicks, various issues with following amplifiers, just to get started on a long list.
Plus the still-valid old timers' warning: ALWAYS do the work to RULE OUT external issues -- connectors, cabling, coax, antennas, programs, power supplies, misunderstanding or ignorance of the manual, power spike scrambling memory, braine pharte, BEFORE tearing apart or sending rig back to factory, or deprecating the manufacturer on public media. Sticking to that rule over a lifetime will save 90 per cent of angst and trouble relating to station apparent rig malfunctions. 73, Guy K2AV On Tuesday, March 1, 2016, Bill Hammond via Elecraft < [email protected] <javascript:_e(%7B%7D,'cvml','[email protected]');>> wrote: > Hi John, > My power dances all over the place (my serial number is 00069). ..... -- Sent via Gmail Mobile on my iPhone ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
