Re: LF: VLF/LF QSO

[Roger Lapthorn <rogerlapthorn@gmail.com>]

Thanks Mal.

Actually I think if you got an NoV and became active on 8-9kHz it would be a real stimulus to others too and you'd enjoy the challenge. Although I know you don't much like beaconing and prefer real QSOs (I can understand this) providing a good strong and stable G3KEV signal on the band would be very useful indeed to others. 

You've already proved that your receiving system is good and it doesn't require too much more from people like G3XIZ and G4WGT (further north) for a slowish DFCW or QRSS QSO to be on the cards later this year. So, some inter-G Dreamer's Band radiated QSOs are not that remote a possibility. Internationally there are 3-4 stations lining up to work you. 

You've done so much already on the LF bands and this would be a real opportunity for you to contribute and win some new records. Actually I think you've been quite surprised by what has proved possible on this band and wouldn't mind giving it a go really, HI.  If it helps with preparing yours, I'm happy to send you a copy of my own 9kHz NoV submission to OFCOM and I'm sure that others would too.

Finally, have you thought about setting up a grabber for VLF, if only to be used during specific tests? Using Dropbox (thanks to John GM4SLV for this suggestion) and Spectrum Lab or Spectran it is extremely easy to set up. Although I'm no expert, I'm happy to share how I did it, if it helps. Judging by the results at the weekend, a grabber at your QTH would be very useful.

All the best

Tnx Roger for the Met office details.

I will approach the 9 Khz slowly and in two stages.

Stage 1

When I have worked all of the UK stations that are active on 137 Khz on either CW or QRS3, most of whom I have not yet heard in spite of the fact I am working all around EU and Russia daily.

 

 

Stage 2

When I am able to hear/see the UK stations with NOV'S active on 9 Khz, none detected so far, although I am able to copy DK7FC and OE5ODL in QRS3 mode.

 

I specify the above criteria because it would be counter productive for me to embark on a project where there would be noone to communicate with.

I think UK amateurs would need to think in terms of Kilowatts and Amps on the lower frequencies like they do in EU and the USA.

otherwise VLF/LF/MF will turn out to be a DAMP SQUIB.

Hi Mal

The only requirement is to inform the Met Office when you'll be on-air - they always say OK - (they do this so they can check if they've had interference to their sensitive monitoring gear) and to submit logs. You would be a most valuable member of the Dreamers and I urge you to submit an NoV application. Looking forward to receiving your big signals soon.

All the best

Stefan es Ossi when you are ready for a QSO let me know.

 From recent observations on both signals I am satisfied that I can receive both at a satisfactory level for a QSO at between QRS 3 and QRS 30 depending on condx at the actual time. I will reply xband on either 137.7 Khz or 502.6 Khz if you can receive satisfactory on those frequencies. I do not have a permit for TX on 9 Khz and then I think one can only TX at a time convenient to the UK Met office.

 

Pse advise when you are QRV
