Having an hour of radio time at the YL's while the Sunday roast was in the oven I fired up the TS450, having put up the pro whip the previous evening. Whilst I had a coffee i tuned round on my remote SDR rx so I could see what the bands were like from home before comparing it to this location.

I noted that on 18 Mhz at least a burst of RF from the TS450 did not kill the wifi connection on my netbook. I found a clear 18Mhz frequency and gave my callsign whilst listening on the sdr rx. To my suprise I heard my signal, weak but readable.  I would say about 3 and 3. I think conditions may have been a little odd as I wouldn't expect the groundwave on 18Mhz to make the approx 30 miles (48Kms) trip back to my home QTH. If I can solve the problem of the wifi cutting out as soon as I transmit on the other bands this would be an interesting experiment on the lower frequencies. I have read a little about NVIS propagation and I guess this is the effect that I am hearing, however for NVIS a horizontal antenna is normally required rather than the vertical Pro-Whip. I hope later in the year to be able to put up a low slung long wire or dipole of some sort at this location later in the year which presumably should result in a stronger signal over this sort of distance.

Whilst on the Higher bands I was pleased to work KB2ZVP on 18Mhz and Z63MED in Kosovo on 28Mhz. Both with the Pro-Whip vertical about a metre from the ground.
