Good radio,but if you run ssb in vech in winter it will drift unless you have the heater going.I had the same problem with the ss360 and ss3900...Its just a souped up 148,and the 148 is a fantastic radio.I run one of the new rci2950dx in car and house,still just 10 and 12 mtrs.73s de n0zna
you'll most likely find that problem in any cb or export radios as none that i know have a temperature compensated crystal oscillator., even a tuning fork drifts with temperature change, so expecting a cheaply constructed cb not to is a bit naive, although at least your more honest than 99% of uk cb'ers that swear their ss360 fm/cobra 148 gtl dx don't drift, the fact they are only using 5 digit counters is neither here nor there when experts start stating facts.
incidentally even a radio with a txco is allowed drift, and it will always be more noticable on ssb, a mode which is far more dependant on stability for good audio.
too prove a point:
specs lifted from Kenwood uk's website for their ts2000x:
Current Drain (approx.)Transmit/Receive = 20.5 A/2.6 A (Approx) DC Power Requirements13.8 V ± 15% Frequency Stability± 0.5 ppm HF Output Power100 W SSB/FM/CW/FSK, 25 W AM
the key one is Frequency Stability, 0.5 ppm, which means at 27 mhz its stable to 13.5 hz either way, not much i agree, but still DRIFT, and impossible to measure on any substandard frequency counter.
to expect a cb at one tenth the cost not to drift, is just downright STUPIDITY.
