Apart from the interesting account of the nulling experiment, below, I was intrigued by the mention of the "Watford Whistle" - grateful if Jim or others could elaborate on this or known power-line tr
This might appear to be "off topic" but I would like to inform all UK Amateurs on this reflector of a discussion group at http://uk.groups.yahoo.com/group/ukc4discussion/ that has been set up for pri
Following discussion at yesterday's Spectrum Forum meeting it was agreed that the RSGB would send in a formal complaint. I've been actioned to prepare a draft. Grateful for detail of the spec that th
Steve, yes - the URL that I referenced mentioned Australia, USA and New Zealand - the USA seem to be making real progress, but not sure of the status in VK and ZL. 73 John, G3WKL John - many thanks i
I posted a note to this reflector that was written for the RSGB's Spectrum Forum the other day - maybe you and others haven't seen it. The position in the UK is that the RSGB submitted a proposal for
Great news. I was discussing the matter with RSGB HQ only the other week and we had decided to send off a further letter of complaint. Will now re-consider what is the best action. 73 John, G3WKL Int
Given that there may be a short break in LORAN transmission this coming Tuesday I thought that I would post an e-mail requesting measurement of the background noise floor, whilst the Rugby transmitte
I'd just like to follow-up Peter's comments re use of his recently developed program to measure SNR as I am keen to get some measurements of the effect of the Rugby transmitter in order to follow-up
Dave, thanks for trying. My travelling didn't happen so I was around today after all, however, as we now know the signal didn't switch off. My thanks to Peter for developing a special piece of softwa
Sorry John, I don't know the times, but I seem to recall seeing a posting from someone on this reflector recently alluding to the "usual first Tuesday in the month" maintenance at Rugby, also known a
Without wishing to raise hopes too much, we may be getting close to Ofcom agreeing to issues a few Special Research Permits (SRP) for operation in the band 501 - 504kHz within the UK. It is expected
I should have added that it might be reasonable to add a separate sheet with the issue about field-strength, assumptions and how you arrived at the figure in the RFI assessment box 73 John, G3WKL Jim
Mal, see the answer to Jim's query. I really wouldn't make a big issue of this. If Ofcom are concerned about whatever we put in for the near-field assessment I feel sure that we will be able to resol
Jim, thanks for raising this issue. The SRP is a generic form that often is related to "experiments" with people asking for permission to run high power (for EME, MS, HF, etc), where the field-streng

John, you need to understand that we submitted the proposal to our regulator in Sept 2004, so it takes its time over here also. Well done, Dave. Hopefully, there will be some more to follow soon. 73
Pete, I would suggest that you mention the work that you have done at 136kHz, etc 73 John, G3WKL --Original Message-- From: [email protected] [mailto:[email protected]
I'm busy building a DDS, but if that fails to work in a sensible timescale I'll need to be xtal controlled, so an agreement where we might cluster for QRSS/DFCW might be worthwhile. This might also b
Walter, individuals will need to apply to use their licence so it will be a little while before any SRPs are issued; hopefully, in time for the 1st March. experimental access they are expecting us to
I'm not keen on another reflector, but someone made a comment a week or so ago that made sense, which was to prefix the title of 500kHz postings. I don't think the suggestion would work in all cases,
