Re: LF: QRP

[Roger Lapthorn <rogerlapthorn@gmail.com>]

I agree Pete. Mal's signal would be a very welcome one on 8.97kHz and the thing preventing many of us VLF enthusiasts from TXing (other than by earth mode) is lack of space for a credible antenna. 

Mal, are you game to give it a go?

Hi Mal and LF

 

Too bad Mal you have a good set up to radiate on 9kc/s to help the interest in this part of the spectrum. Most can not TX on that band because they just do not have the space with an excellent antenna. There are a fair number of people in UK who have invested in good RX systems that will work in limited space with a small antennas on VLF. IMHO VLF will never be like a highly populated band like the HF bands but it has it's followers like the number of reports SAQ gets every time it transmits. I would like to try to receive a signal from the Scarborough area approx 190miles North of here.

I have made it quite clear that presently I am not interested in Transmitting on 9 khz and if I did you would certainly hear me.

I am told that I have the strongest signal on 137 and 500 khz from EU and the same would apply if I could be bothered to TX on 9 khz.

Some years ago there was over 30 countries active on 137 CW and now it is down to just a few, 500 khz is likewise not worth the effort anymore and 9 khz is not worth the effort as far as I am concerned.

Righto Mal - so when will we finally see a decent 9 kHz signal from that famous Scarborough antenna?

Why do some insist on flogging QRP on the LF bands. The object should be to generate a signal that all can hear or see.

QRO is more appropriate on the lower frequencies otherwise the RX operator has a hard time digging the signal out of the noise.

The TX operator puts no effort into the exercise. QRP and Earth mode equally disaster for those making an effort to detect signals on LF.

I leave gas pipe and electic wire underground propagation to the local gas/el installer and do not believe all you see on twitter and tweet

by others.
