Thanks for the information AJ. I doubt I’d ever use the SH as a ‘radio set’ but as usual curiosity gets the better of me.
My usual ‘quick test’ of a receiver’s VHF performance is to tune to Manchester Airport’s recorded information service on 128.175MHz AM. This is fairly weak but readable here. Here is the situation as found this morning on my various receivers:
AR5001d: indicated signal -99dBm, readable..
SDRPlay/HDSDR: indicated -60dBm (don’t know how it gets this figure), readable..
Signal Hound using Audio Player utility*: indicated -110 dBm, readable but not as clearly as the previous receivers..
Signal Hound/HDSDR: indicated -113 dBm, carrier visible but unreadable almost no audio recovered. This with RF gain at various settings..
*Set for AM, BW 8KHz
