QMX+ QRP on 8m FT8

 My QMX+ should work on 8m TX just by adding a band configuration using PuTTY. 

I successfully altered a parameter with this PC and PuTTY, so I must be experiencing "finger trouble" with PuTTY at the moment as I cannot (yet) get it to work in terminal mode. My trouble is I cannot remember what I did!

I should be able to use the 6m TX LPF and make no internal changes. RX is a different matter, as I would need to create a new BPF, something which is now beyond my fine motor skills. So I shall have to accept that my 8m RX will be deaf.

UPDATE 1220z:  Indeed it was finger trouble!  My QMX+ is TXing about 2W on 40.68MHz FT8.



UPDATE 1528z:
Already spotted on 8m FT8 in the USA, Greenland, Dominican Republic and Puerto Rico with the QMX+. It works!!

UPDATE 1610z: This once again shows that the MUF reaches 40.680 MHz far more often than 6m, once again showing a very small amateur band at 8m worldwide would be so useful for propagation research. As I have said very many times even a 5 kHz, digital only, low power allocation would be of use.
