Hello Hans-Albrecht, I am not involved in the planning of this LF meeting, I only forwarded Carl-Henrik's (SM5BF) message to the LF list. If you are interested, please contact him directly at the add
Hello Mike, I got my copy of "LF Today" in the mail today. A nice addition to my slowly expanding longwave library! However, there is an error on page 109. The QRSS signal at the bottom of the screen
Dear group, I have the 1947 edition of Terman's Radio Engineering (in "as new" condition!). It is the third edition / fourth impression, copyright 1932, 1937 and 1947. Does anyone know how many editi
Most cannot use a keyboard and just fumble along, CW would be the easiest option I agree. CW is clearly the best choice for word processing and it is ideal for writing computer programs. Who needs a
By the way, your for sale notice dosn't say how much for the keyboard. Well, the picture was taken before I wrote the final line of the ad'. It is really amazing that the CW message survived the aggr
"What?" said the boss. "QED mate, Quality Eats the Dust !" I've never heard it before. I was thinking about "quod erat demonstrandum" http://mathworld.wolfram.com/QED.html I will add "Quality Eats th
Hi All, I am playing around with Jason in fast mode. There is a little PIC controlled beacon centered on 3577.000000 kHz at the moment. Fast but no turbo. Reports are welcome. Sorry for this off-band
Hi Scott, yes I will be on but I'm quite pessimistic about the chances on 80m. I am running only 200mW at the moment. So far, I have got one report from Germany. 73 Johan I'll have a listen tonight f
Hi Alberto, thanks for the report! I also got reports from Steinar LA5VNA in JO59JQ Hartmut in JO52HO Pierre ON5SL in JO10TT but your report was the best DX :o) 73 Johan SM6LKM JO67MR -- No virus fou
I found this on another reflector and thought it might be interesting to the LF prop gurus. 73 Johan NDB List Information and CLE Pages: http://www.beaconworld.org.uk/info.htm http://www.beaconworld.
Also needed is a clear indication which end is the handle and a note that the mains plug may be harmful if swallowed. Oh dear... Johan SM6LKM Perhaps this would be a suitable sign.
Heard from a swedish tourist on a guided tour in Rome: Guide: "This is Forum Romanum, a fantastic sight, isn't it?" Tourist lady: "Yes, it looks very nice already. I'm sure it will look great when it
Uwe, there is a lot of VLF information on www.vlf.it. You can find information on the Alpha system on www.vlf.it/alphatrond/alpha.htm. 73 Johan SM6LKM Uwe Wensauer skrev: many thanks do You know wher
J, if you follow Jim's suggestion to wind a solenoidal coil, I would suggest using G4FGQ's program "solnoid3" to estimate inductance and Q. The program is available here: http://www.btinternet.com/~g
If one has DFCW capability, numbers such as 73 can be transmitted in binary form. For example, a 7-bit DFCW "word" has a range 0..127. No other CW character has as many as 7 elements so there should
I like the idea of omitting default information from the transmission. This philosophy can be extended even further: Default QSOs can be had without sending anything at all! Signal reports are not ne
A Pi filter with all X = Zo behaves like a lumped circuit version of a quarter wave transmission line. For 50 ohms and 136.75 kHz that is: C1 = 23.3 nF across, L = 58.2 uH along, C2 = 23.3 nF across
Hi Dave, The puzzle is why the Ropex has problems with a 50 ohm match at 136kHz if the coil is grounded? The match is the same on an SWR bridge whether the pi cct is in circuit or not. The Ropex prot
