I have the same variable capacitor which I have used for a rx antenna tuner, but not the knob + dial. Anyway, I can't find it today If the other suggestions do not find one, try the UK Vintage Radio
I have been testing some real barbed wire fences of 1500 metre long, which showed a very narrow beamwidth in one direction. If you have the opportunity, there are many usuable fences out there which
To return to this thread, I have realised that tuning the 1103 at LF is much simpler than previously suggested - see http://www.rosestone.me.uk/Degen/VLF.txt Having dug out my DE-1103, I tried it on
A few observations - http://www.rosestone.me.uk/Degen.html including details of how best to use the 1103 at MF/LF and below 100kHz. If you should order an 1103 from the reputable dealer Liypn, you'll
Perfectly good signal in Stockport, Richard (on a small loop) I have a CW beacon running on 501.7kHz. EIRP about 100mW. Reports very welcome. It will be on until morning. 73 Richard G3CWI
Daniele - I see from the schematic http://radio-timetraveller.blogspot.com/2009/08/tecsun-pl-600-review-and-schematics.html that the MF-HF input to the PL-600 is a LPF followed by a balanced mixer Al
I have a service manual in German - it does not include the operating instructions There's quite a lot to scan but I have made a start and uploaded a few pages to http://ukradio.info/D2006/ I will do
Hi Chris. Just tried the link , the item has been removed, is 'RF Padboard; the recconised name for it? 73s. Ken M0KHW RF Matrix PadBoard 149x114x1.6 Prototype Circuit Board http://cgi.ebay.co.uk/ws/
In that quantity the 4148 costs less than one pence, so before you go buying stamps let John pull a couple out of any scrap pcb he has lying about - there's always some small glass diodes which would
Skelton? Oh, and re tinitus, I think mine is nearer 10.125kHz (only the UK OM's will understand ;-) I have just had a look & 15.1 kHz is stronger than Anthorn (22.1kHz) & I am only 150kms (93 miles)
Alan - I see from your own page "A History of Rugby Radio" that the Litz wire used in the 16kHz loading coils was 6561 strand (81^3), and I recall hearing the erstwhile Chief Engineer (who's name I f
A dry joint may not cause the QRP op so much smoke, but it will surely negate the expected gain in Q? If anyone wants a solder pot, I have one that I've been meaning to eBay it so let me offer it her
Sorry I only post OTs on here, but it may interest TA om's to know that The Saarlouis tx of Europe 1 has been radiating considerably more of its 2MW towards the N + E since a partial mast collapse ye
Geological surveys have long used small detonations in conjunction with an array of microphones - maybe there is no plan for LF radiation, but if there is, we'd all be interested to see the details -
JB asked Does anyone here know how the Kenwood TS-440 fares at 500 kHz.? Mine does a fine job down at 137 and equally well on the Lowfer 160- 190 kHz. range, but it seems a little "deaf" around 500.
There's a D2155 SLM on eBay now for next to nothing. Lovely instrument, 0 - 660kHz. It is calibrated +20 to -110dBm dial marking, in 75, 140 or 600ohm bridged or terminated. I measure the bridging Z
It's always impressive how strong those dx sferics are - this weekend there were no storms exactly 'local' to the British Isles, but the QRN levels were high. I keep an eye on wetterzentrale.de at ht
The dreaded metal filings in a meter are, perversely, best removed with a pointed magnet tool. The d�bris will jump off if you point a sewing needle at it, where it sits in the gaps around the magn
