I am afraid not Gary, I have been seeing these and getting non-delivery notices for years. I stopped signing my messages with my address when I realised it was being harvested. Anyone can "forge" an
Hi all, I am very please to see not everyone sticks to a 12 volt maximum supply voltage One though that occurs to me is that if one side of the MO transformer is grounded in oven service........one o
Hi Warren and listeners.....yes there was a sudden KP=6 which depressed the Dst to -65nT and Steve W4EEE's plot of DCF39 was noticably lower than previous night. I think things should recover fairly
Hi Gary, the mini-whip is not bad but where you are located it could be the size of the 252 signal is producing some intermod/harmonics. Do you get the same effect on a wire, or passive antenna? I ha
Hi Ken yes I appreciate the usage. I was a little concerned that if the transformer was not designed for that kind of use it might not necessarily have sufficent insulation from that end of the windi
Hi John, sad to say, it does look very likely. I dont know the family but the location is correct. I know he has not been too well over the last year. Alan G3NYK Message: Friends, Is this G3AQC? John
Hi Dennis I guess insertion loss is fairly easy to deal with at these frequencies. Would it not be better to consider what you need to reject rather than how little to accept? This would make the tui
Hi Jim. whist it involves a change in "usage" from our end it would not seem unreasonable to ensure that the US stations have a chance of hearing us without nearby swamping. I think this is an intere
Please dont "steal" subject lines !! I would hope everyone here would have enough intelligence to use an address book and type a relevant subject....at best it darn right rude to the originator !! AN
Hi Roger you will find that the late Reg Edwards programs GRNDWAV3 (I think) gives a very good idea of ground wave strengths. I do have an article here (somewhere) from Jack Belrose with I believe so
Hi Warren thanks for your concern....yes I am fine if somewhat overworked at present, and I have also been running up a new computer so having to transfer all the apps....I promise I will get it up a
Hi Jim, I guess that could be frustrating to some who maybe do not understand the limitations enough, but would seem to work ok within them. The ideal method at 136 as you say was to use Loran sideba
Ah Warren you mis-interpreted that picture!! it was a Reliant Robin fitted to the base of a 160m whip :-)) Alan G3NYK Many years ago there was a picture in QST of a Robin Reliant fitted for 160 meter
Hi John contact the guy at HQ who runs the Museum. I dropped in an "RSGB" diary for 1926 which had a call book bound into it he should be in there. It was in Arthur Gee's (G2UK) effects. I should hav
Chris try single ended Class-E very simple, ok they need a modicum of tuning but have been used successfully by Mike GW4HXO and Finbar EI0CF and others up to about 500W. I have some notes on experime
Hi Horst, Mmmmm your problem may not be the antenna it may be your use of the level measuring set !! A "good" receiver would work well at LF off that kind of aerial. You must remember that these LMSs
Ah the dreaded laptop. Ok the isolation that is agood idea in that case you must make sure you have some Rf grounds somewhere. Laptops seem to float there is not reason (for the digital engineers who
Hi Andy observations over several months by some of the VLF group suggest that whilst there are some radio effects from meteors at low frequencies they are very weak and difficult to be sure of. In g
