This was indeed a surprise to hear you so easily on 20M CW from W0C/SP-111. It was even more incredible to be activating above 3000M on the day before Winter Solstice. The temperature was about 10 C, with warm sun, although I hiked most of the way up in light snow.
You can see the antenna and pole near the summit in the photo above. Can you believe the sunny scene?
I used the usual rig:
KX2 at 10W
20M inverted-L wire at about 5M
Homebrew high-Z tuner
I’m amazed that you could hear me yet another time. Please thank your neighbor for helping us by switching off his noisy LED system!
What is even more amazing is that 2 minutes before we made our contact, ZL1BYZ called me and also made contact on the same frequency, with about the same signal levels! He also has made numerous SOTA contacts with me and other SOTA activators.
This is not the first time that I have contacted EU and ZL in the same SOTA activation, but it seems magical to have these contacts right together.
Also several times recently I have been hearing my own signal echoes, actually my own signals coming all the way around the earth via the long path, while calling CQ or in QSO. Even more often, I hear these echoes on QRO chasers - they are very easy to hear with the KX2. This is on 20M and 17M CW - but the bands are certainly not dead, and it is always amazing to hear these echoes and to realize what they mean. This is not an artifact of the radio - the echoes come and go and change with the propagation, as well as which station is being heard.
At first I think these signals are QRM from another station on my frequency, but when I stop, they stop, and when I send, there they are, audible for just a fraction of a second after my signal.
Many of our Colorado SOTA peaks are in somewhat undeveloped areas, so noise levels are often very low. This makes it possible to hear echoes and weak signals that I can’t hear at home.
