23cm activity contest this evening

My first test on 23cms TX will be tonight. I have only got the 2 element test antenna and 2W PEP, so I hope I can copy (and work?) any locals that may be on, otherwise I shall have to set up some skeds. 

All is set up. In the past my only (ever) outing on 23cms was on RX only with a borrowed converter and homemade 4 el yagi. Like then (1970s?), everything is indoors firing through the shack window.

These tests are all in the shack. Later this year I hope to try some /P on 23cms.

Surprise visitor - NOT amateur radio


We often get Muntjac deer in our garden, but rarely see them. Imagine my surprise when pulling back the curtains!

8m QRP FT8 (Tuesday)

My QRP 8m FT8 was switched on at 1025z. I am on 40.680 MHz with an audio offset of about 1950 Hz. I am TXing first. No spots.

UPDATE 1820z:  No spots all day. Disappointing.

10m QRP WSPR TX (Tuesday)

My 500mW WSPR beacon was turned on at 1025z. So far, no spots.

UPDATE  1255z: 7 unique stations have spotted me today. Furthermost is FR5ZX (9740km).

UPDATE 1822z:  19 unique stations spotting my QRP.

Plans for the day (Tuesday)

 Today, I plan the following:

  • 8m QRP FT8
  • 10m QRP WSPR TX
  • 23cm local tests ( I think tonight is the 23cm activity contest).

Many will remember this famous transceiver from the 1980s. It was made famous by featuring in the TV series "The Professionals". A copy of the PF8 service manual is available here.
