M0BXT and I usually have a natter on 144.55MHz vertical AM on Mondays at 8pm. We were on last night but got distracted doing some tests on all 9 HF bands using QRP AM.....
Starting on 10m and working down to 160m we very briefly exchanged reports at 4W and then with some 10-20dB less to see how signals compared across each band on our end-fed antennas tuned via an auto-ATU at each end.
I have to confess to a brief AM QSO on 30m (shame, disgrace!!) but only for 20 seconds at most so no harm was done to the planet.
We managed solid QSOs at over S9 over our 2 mile path on all bands apart from 24MHz where signals were weaker, maybe because our wires had deep holes in radiation on this band. The best band was 80m where signals were 59 + 50dB or so. 160m was also pretty good.
M0BXT and I hope to have our first two-way single valve or single transistor transceiver QSO in the next few weeks on 80m but this will be CW.
