From Dave G3YMC Although I am in favour of keeping the top 100Hz or so of the band for slow CW, as per current usage, I do not think we should have any other sort of restrictive bandplanning. With cu
From Dave G3YMC <Regarding the B.W. of the antennas: It's interesting that some stations <have antennas with only 200Hz B.W. How do you get this high Q-value? My <antenna covers the whole band and I'
From Dave G3YMC I have calibrated my receive set up against a quality signal generator, calibrated in dBm into 50 ohms. I won't bore you with the actual figures, but they show that the use of S meter
From Dave G3YMC Below is a corrected version of the mail I sent earlier. My signal generator is calibrated in dB of attenuation relative to +13dBm, and I had incorrectly converted my figures into dBm
From Dave G3YMC The recent discussion on receive loops has largely involved relatively small multiturn loops (frame and ferrite rod). I have no experience on these for 136. However I would like to co
From Dave G3YMC The RSGB's programme for studying propogation on the eclipse was in April 99 RadComm. This suggested various monitoring programmes for 73 and 128 (sic!) kHz. I e-mailed the author G3N
From Dave G3YMC Thunder static on the band today Friday is constant s9+20 with no gaps and I can hardly copy DCF39 through it. Presumably if it is like this next week it will make monitoring difficul
From Dave G3YMC No radio reports on the eclipse, but just to say that the visual eclipse in Salzburg was superb (2mins 6secs of totality in (surprisingly) an absolutely cloudless sky). No pictures I
From Dave G3YMC This is a follow up on the mails earlier this month on this subject. Today, assisted by Steve GW4ALG, we measured the rf current in my transmit loop in a similar fashion to Steve's me
From Dave G3YMC <The loop design programs RJELOOP1 and RJELOOP2, written <by Reg / G4FGQ, both include induced ground loss when they <compute the total loss resistance. Thanks for the information on
From Dave G3YMC I must apologise for forgetting yet again to listen for Roger this morning, despite reading his mail first thing! However it should be noted that they seem to have changed their maint
From Dave G3YMC Further to other suggestions for programs for calculating distances. I use the VHF contest logging package written by G0GJV and available at http://ourworld.compuserve.com/homepages/m
From Dave G3YMC Having read in more detail the German original of the proposal to allocate various LF frequencies to the pager service I note the following. The questionaire appears directed at poten
From Dave G3YMC Comments on recent e-mails. 1. I cannot comment at all on the ARD receiver, never having seen one. However I would agree with the statement that a 500Hz filter is too wide. I have bee
From Dave G3YMC I was about to reply direct to Alan about his receiver bandwidth suggestions, but other mails now demand a reply to the reflector. Nick G4WHO sums it up very nicely when he says that
From Dave G3YMC Message written by G3XDV <I have a sked on the 73kHz band with Peter, G3LDO, on Tuesday <morning (the 5th)between 0700 and 0745UTC. Frequency will be <71.90kHz. Any reports would be w
From Dave G3YMC I gather from later mails that the tests between G3LDO and G3XDV may have been on QRSS. If that were the case then the interrupted carriers I heard on Tuesday and Wednesday may well h
From Dave G3YMC Derek G3GRO is kindly repeating the 136 talk he recently presented to the Bracknell Club next Wednesday. All visitors are welcome. We hope to have some receiving capability so it woul
From Dave G3YMC Firstly may I say how nice it was to meet many of you at Windsor on Saturday, and I am sure we all gained a lot from it. We also had most interesting discussions over dinner and it wa
From Dave G3YMC Interesting. I had dinner with Geri DK8KW on Saturday evening at Windsor, and even earlier saw him at the operating position of GB4RS. Perhaps it was his second op left back in German
