It is not coming in through the LF reflector Actually, some of it _is_ coming in through the reflector; the false PayPal messages and the Nigerian bank transfer scams being recent instances. Seldom
Thanks to blacksheep using SpamAssasin I guess it does reduce the spam on this list enormously from what it could be, and in fact it is a very small percentage of the spam received here. However it i
From either an engineering standpoint or a scientific standpoint, I'm not very comfortable with the term "sea gain" being applied at LF. The sea is vastly less lossy than land--conductivity of 5000mS
Nothing magic about it but its usual proportions for HF are still impossible for amateur 136 . (how would one keep the loop up ? ) Balloons. Lots and lots of helium filled party balloons. :-)
Do you think it will work on LF too? :o) According to those "actual equations," I am convinced it will work exactly the same at LF as it soes at wireless LAN frequencies! Not many other products can
Sorry all - its farcical I did just the same thing! I'd feel better knowing that, but I'm afraid I just did the same thing again myself. Apologies again! The only excuse I can offer is that this time
Glad its of some use, yes print in the Lowdown with pleasure. I can let you have the original source material if its any easier than taking it from Alberto's page
Andy, The Navman Jupiter board is a very interesting product. I had previously obtained a little information from their Web site (not as easy to navigate as one might hope) and was delighted today to
Up to now, the only way I found to synchronise the software and the hardware clocks is to switch the computer off and on again. Any Windows guru on this mailing list ? I used to write applications f
During lf transmittings of your own station there will be no clocking because the DCF77 receiver will be overloaded (what is it in english "zugestopft"?) In American English. at least, "overloaded" i
That is one possibility, Jean-Louis. Any mode that depends on knowledge of bit timing can be made more efficient through external synchronization. This would include any of the PSK modes, for instanc
In the month since the thread started, interest has picked up on this side of the pond in using GPS to synchronize timing of digital modes. No longer having to hunt and test for bit and frame timing,
It all started so nice , and then there was QRSS . (snip) I wrkd over 200 differend stations two years ago , and only a fw are left I'm afraid I fail to see the connection here. Are you fellows seri
Hi Walter, I wonder if the shf stations used modulated cw? Looks like they used Gunn oscillators, which could have drifted a GHZ doring the transmission At that frequency, they were using an incande
Or am I being too cynical? No. I guess with Rhode Island being the smallest state, the university needs any revenue stream it can whip up. Center-loading an antenna...old news to us, cash cow to the
This is not a commercial broadcast station. It is a 1-watt DC input station operating under Part 15 of the FCC rules. I believe it has only been heard in its immediate area. That is correct. Europea
Depending how majordomo is set up, yes. One of its options is a feature to allow certain administrative tasks to be done by sending messages to the list by e-mail. Majordomo watches for certain keywo
Actually it may not be such a daft train of thought. Disconnect tower grounding strap(s) - there should be at least one (inteded to "arrest" lightning ?) and check to see if tower really is "earthed"
