Hi All, Loran-A, post-war, was centred on 1950 and 1850 kHz. 1950 was almost entirely North Atlantic, 1850 Pacific and some American. If you heard 1850 in the UK it was genuine DX. All Atlantic were
Nothing seen here, Alan. 1630 Walter G3JKV. Hi all, does anyone claim the signal on about 137.62 (drifting slightly HF abt 1Hz per 2 mins with 0.7Hz sidebands....which might be beats as it crosses a
Sounds like we're all interested in seeing an LF aerial the size of a 35mm film can! Perhaps it should be put on one of the websites since this reflector won't pass attachments. Walter G3JKV.
Yes, Roelof, have observed this noise pattern quite often, also seen on MW. No idea of the cause. Walter G3JKV. Hello all, After tinkering with the waterfall color palette of SpecLab for some time, I
Alberto, They switch off Alpha whenever they get behind with the electricity bills! True! Walter G3JKV. Excellent copy of SAQ this morning. I prepared a page with a couple of screen captures and an a
The theory behind the "height gain" observed using small LF active antennas at different heights has to do with compression of the near-earth LF potential gradient caused by the grounded "mast" holdi
John, "Height gain" at LF/MF is caused by quite a different mechanism from the "height gain" at VHF. VHF observations are irrelevant, I'm afraid. Walter G3JKV. -- Original Message -- From: "John RABS
Or any other battery rx for that matter if your binocs (and arms) are strong enough! The effect can be seen on MW b/c stations. Walter. Sticking to the KISS principle, how about hauling say, a batter
Higher the better but the added gain is a function of SQRT(height) so there's a practical limit. Most gain in the first 20m. Walter G3JKV. -- Original Message -- From: [email protected] Tra
Watch out for Kinabalu Laurence - it's highly magnetic! Used to totally screw our compasses when I was flying out there in the 50's. Walter G3JKV. Greetings - Im packing my wellies and pack-a-mac but
Apologies if it's annoying anyone but the silent carrier on 136.52 is me testing with Peter G3PLX. Trying to get some power level measurements. It's going off now (2250) anyway. Walter G3JKV.
I found a Decca Aerial Testing Signal Generator Type 1615 at a junk sale a few months ago. It's basically a xtal osc/driver/PA transmitter for LF (Decca freqs 70-127 kHz). Very easily converted for 1
Re Decca 1615 SG It's a very old tube-type device designed ca. 1960. Tube line-up 6AM5, 12AX7, two 807's (later models 6146's) No risk of blowing up FET's with this one but doubt if the transformer d
The reason was that the "galloping horses" (actually Loran-A) were confined to 1950 kHz in the North Atlantic area which included Eastern seaboard USA. The Pacific area got the 1850 kHz channel. Ther
Don't know about Loran interfering with MSF but back in the 60's when we were experimenting with early Loran-C we had a lot of trouble with HBN 75 kHz causing synchronous intereference to Loran. With
A number of TAIT T801 frequency standards have just appeared on the UK surplus market. They're ex-cellphone bases and I understand have been ditched in favour of GPS-locked standards. Consist of an R
