Thanks Rik for the report. I made two changes: I raised the far end of the antenna from 9m to about 15m, and I got more RF out of the pa by foced-air cooling it (standing a fan heater next to it!!).
Good weekend with low static and fairly low electrical QRM (everyone out enjoying the sun rather than watching TV), but high wind resulted in the antenna being lowered both afternoons. Hearing DF0WD
Dick, PA0SE, and others have recently been using a multiplication factor of 1.83dB to obtain ERP. This is the supposed gain of a vertical antenna over a dipole because of ground reflection. Is this r
Saturday 17 July Got up early (0540UTC). Pleased to find no local QRM and no QRN. Conditions good, too. Received seven mainland Eu stations before my first G! CW contacts with: PA0SE (gave 579; got 5
This is not very modest by UK standards. My garden is 35 x 90' and I can still put up a useful antenna for 136kHz. It requires some ingenuity - I am using a loading coil at the top of the mast, for i
Yesterday I installed abt. 20 radials (10-35m) to my antenna system. But there was no significant change of the antenna current. The current is abt .6 A with and without the redials. Can anyone expla
John, I will download 5.08 and test it as soon as possible (but desperately busy this time of year editing the RSGB Yearbook). Will let you know the results. I really liked the facility to define co

Agreed. I have had several flash-overs, including setting fire to a plastic drain pipe which I had assumed was made of an insulating material (brand new conservatory - not a popular thing to do!). I
Pleased to read so many reports of successes this weekend, especially from DL and OE. Unfortunately, not such a good weekend for me! Saturday 31 July Got up at 0620UTC but bad noise from next door at
Mark, I tried to e-mail you direct today but got an error message. Is [email protected] correct? 73 Mike, G3XDV (IO91VT) http://www.dennison.demon.co.uk/activity.htm
Oops - our trusty proof readers didn't spot that one until too late! One of things the article said was that the effects of the eclipse may last a while, especially as the zone of totality changes w
I now have this software (thanks, Rik for solving my download problem). It is just what I have been looking for as it plots the level of signal, and the noise level if the signal is not permanent. I
An unusual weekend. I had to work most of the time, so little activity, except for listening (watching) for the earth tests from John, G0AKN. Saturday 7 August: Local noise on 136kHz in morning. Tune
how about a cross band QSO 73/136 in Slow CW. 73 de Toni, HB9ASB Ho Toni. I would love to, but I think we have a better chance later in the year for the following reasons: 1) I have been plotting the
Sorry, brain not working. The frequency I will be transmitting on is 71.80kHz, not 72 ..... Mike, G3XDV (IO91VT) http://www.dennison.demon.co.uk/activity.htm
I will be transmitting on 72.80kHz, QRSs (3s dot length) at 0900UTC tomorrow 14 Aug and Sunday 15 Aug. There will be some normal speed CQs from 0845UTC. Any reports welcome. Mike, G3XDV (IO91VT) http
Very little radio this weekend as I had to work both days, but what I did proved useful. Saturday 14 August Very low noise, but no time to enjoy it. Spent 15 minutes on 136kHz. Worked PA0LEG (gave 32
