Listened to Qso friday 25/02/2000 at 10:45 between MM0 ALM and GM3YXM/P. Checked sig. strengths of both stations on S meter,around S9 so meter quite accurate. MM0ALM S 8-9 GM3YXM S 7-8 So your /P sta
Hi Rick, Heard you here in south of England Sat 26/2/2000 at 20:40.Readable signal at 4/3/9.Called you twice but no copy your end! Will try again.73s Laurie.
Hi Peter, I dont think resonant radials are going to be very efficient unless quite high! But to resonate I found it best to tune the radial system against ground! as though it were an antenna.This n
Hi Dave, I also spent a frustrating weekend! Afraid I heard nothing of IK5ZPV.Called OZ8NJ many times, his sig 5/4/9 but no reply .I have been calling DFCW for several weeks now late evening, but no
I saw the following signal, strength "O" on 137.692 Khz. at 2100-2110 tonight 20/03/00. "CQZP3XK" I replied DFCW and QRS but no response! Was this you Valerio? if so it was a good clear signal, no pr
Hi Valerio, Thanks for your mail.I will look out for you this evening on 137.7,if not seen by 2110 I will transmit on same frequency.I will use slow CW 2 sec dot. I will also be looking for you and G
Hi Valerio, Looked for you on 71.735 at 20:30-21:00 nothing seen.Saw G4GVC and M0BMU at this time.Saw your CQ on 137.7 at 21:00 and replied QRSS but nothing further seen from you.However your sig sta
Hi Bob, Re. your comments on "meander" Ants, subsequent modelling did show a small increase in R.Res using a 3 wire top with the centre wire only connected to the vertical.I will try your idea of a s
Hi Marcus, Many thanks for QSO last nite,your sigs were good "O" at first but later QRN very bad and I lost you sri.I have been working on my Tx ant since our first contact,so I wonder wether you not
Bob, I have now had a chance to do a bit more modelling.I tried an aditional "droopy" top wire with the followihg results:- 1) No change in R.Res! 2)Change in Xc from 2600 to 1900 ohms. I suppose thi
Hi Valerio, Thanks for your mail of 23/3/00.Had to be away from home all day yesterday so could not set up schedule.Will look for you tonight DFCW at about 2100 If no contact will try again at 0900 o
The possibility of transmitting from an ex Decca site is very intresting I would like to put foreward a suggestion for an experiment.Theory has it that the radiation pattern for a much shortened vert
Many thanks for all the comments on my suggestion especially James M0MBU for your support..I agree that it would be necessesary to have min coupling between the two ants, and I am sure that the big a
Thanks again for various comments. 1) Amp-Metres this is of course understood,but it is not significant since the currents will be adjusted to obtain equal powers in the two ants. 2)Dave ZL3FJ is con
Hi Tom, Glad somebody remembers my antenna rig.It did noble service around the clubs, as well as its main job of evaluating Delta Loop configurations.see RadCom 1974. The calibrated Rx was stolen som
Hi David, I should be in ground wave distance from you,and would be happy to give comparison reports of your home station against beach portable,if this is any intrest to you. 73s Laurie.
Hi All, When I first set up my 136 station I put up a Marconi "T" vertical ant. 15M high 30M long.The best ant. current I could get from my 400 watt amplifier was 1.8 amps.The measured ground /coil/c
Hi David, Sorry I missed you at the weekend from Hastings,I didnt know what time you were operating,and I got rather busy with my new ant. Re current I guess that it depends on wether its going into
Fantastic signal here from Puckeridge! I used calibrated attenuator to obtain following comparitive signal strengths. Stn. Strength Time DCF39 S9+47db 1600 G6RO S8+4 1615 G3WSC/P S9+30 1705 ON6ND S9+
The performance of the Decca Ant. is quite intresting, the "gain"or at least the advantage over the normal amateur installation appears to be at least 20db (comparison with G4GVC at this location for
