I thought I would try some 2 meter WSPR. The Barometric pressure has been high for several days the other morning was quite misty, maybe a chance of some DX.
On VHF above 6 meters there are a couple of problems, any Rig may be easily be 500HZ off calibration and there still does not seem to be an established dial frequency for WSPR mode.
WSPR incidentally according to our wonderful national magazine Rad Comm which arrived today, 20th March 2009 is a ‘brand new mode’, ‘rather difficult to get going’ and ‘not capable of any QSO mode communication’. I know it takes time for articles to get published but I am sure glad I don’t rely on our National Society to keep me abreast of the latest in Ham Radio.
Anyway, back to frequencies. I carefully calibrated 2 rigs against GB3VHF and G8EUX calibrated his with a ‘posh’ bit of test gear. We were then both pleased when our RX’d signals reported 2 to 5Hz difference.
The French stations tend to use a dial frequency of 144.48800, a table on the web says 144.48850 after a short period of operation the concensus of opinion settled on 144.48860, there are other frequencies published too.
We had better get these frequencies settled if we don’t there will an awful lot of wasted time and effort.
We still need to fix and confirm dial frequencies for 23cm and 70cm.
At this time the frequencies in use are:-
Band Dial freq USB (MHz) Tx freq (MHz)
160m 1.836600 ………. 1.838000 – 1.838200
80m 3.592600 ……….. 3.594000 – 3.594200
60m 5.287200 ……….. 5.288600 – 5.288800
40m 7.038600 ……….. 7.040000 – 7.040200
30m 10.138700 ……… 10.140100 – 10.140300
20m 14.095600 ……… 14.097000 – 14.097200
17m 18.104600 ……… 18.106000 – 18.106200
15m 21.094600 ……… 21.096000 – 21.096200
12m 24.924600 ……… 24.926000 – 24.926200
10m 28.124600 ……… 28.126000 – 28.126200
6m 50.293000 ……… 50.294400 – 50.294600
2m 144.48860 …….. 144.490000 – 144.491000
