The next big accessory that Elecraft or any transceiver manufacturer could come out with that would sell like hot cakes would be a “TU 5NN” Detector or T5D for short.
In a CW pile-up with a large split of 15 kHz or more, it would ignore all those who keep calling after the DX replies to a specific station and would instead zero in on the responding station, allowing you the DXer to put your transmitting VFO on that freq.
With PT0S generating such huge pile-ups, and with wanna be DXers from Lidville calling and calling regardless of the circumstance, it would seem to be a worthy addition to the DXer’s arsenal.
Of course, with everyone eventually owning one, the purpose would be defeated. Also thwarting its effectiveness would be the non-T5D owners who would constantly send TU 5NN throughout the split range as a new form of jamming.
Oh well – it was a good idea for the 15 seconds I pondered it…
I worked PT0S on 80m very early in and believe I will have to be content with that as my only contact with them. Twenty minutes here and 15 minutes there on the other bands have resulted in little more than fantasies involving my sledge hammer and the rigs of inconsiderate/idiotic lids.
