How will you be determining effective radiated power? Isn't ERP pretty much _defined_ in terms of field strength? 73, John KD4IDY Of course. But the reason for doing such experiments is that, believe

This is especially true during HF contests when the oprator gets tired at the end of the competition (you know, when those headphones start to irritate your ears...). It's sometimes easier to put th

I have been rather busy lately and have not provided activity reports. The only QSO of interest last weekend was with DL0FTZ/P on QRSs, exchanging 'O'/'O'. Mike
I have very recently downloaded Spectran, and am very impressed. Plainly there are improvements to be made and I only have the Beta version, but it appears to be just as sensitive as Spectrogram whil
When you say "machine" modes, are you meaning CW decoded by software or by the brain (be it aurally or visually) ? There is a profound difference... 73, Alberto I2PHD This is all-important. Extremely

Lastly, and with reference to recent comments on the reflector, perhaps a more correct term than "machine modes" would be "machine-assisted modes"! Regards Kevin, G1HDQ At the risk of winding everyon
I have been playing around with feeding differently derived audio into the two halves of stereo headphones with some interesting results. I will report in detail when the tests are complete. In short
There has been some stinging comment on here in recent days on 'dyed in the wood' CW operators, which perhaps I have to admit to being. The implication is that if you persue such modes you are a lit

Yesterday there were three major solar flares (two X class and an M). There should be a major impact on LF conditions as a result, as well as auroras and HF fade-out. See http://www.dxlc.com/solar/ f
How do you use the Spectran frequency scale when you are on LSB? I use LSB for this reason, too, and had troubles with Andy's Hell until I twigged that a dot at the top of a series of symbols probab
A couple of weeks ago, I connected up my ex-Puckeridge giant Litz coil (see my web site for a picture). I used a variation of the stripping/soldering method described by Jim, M0BMU. He recommended wr
The CFA was described in Radio Today magazine last October. In the Feb 2000 edition a phasing unit (essential to correct operation) for an 80m CFA was described. Back numbers are available from sales
Does anybody have recorded sound of Visual-CW (as *.WAV with reasonable length) where the signal is not hearable by ear? Could we have such a reference sound to compare the results of processing? I w
So we might think that it took some 10 hours for the faster material to get here, or was it the real fast stuff the occured as you heard the signal? The only time I have recorded an enhancement of th
In my early days of Ham radio I visited a radio ham who used one of those old metal spring double beds as an antenna. The bed was connected to the hot end of the ATU and the other to the water pipe
I am trying to work out how to use a bandwidth of -10Hz, before he removes it from the menu! Don't remove this one. It should give better than infinite signal to noise ratio. You should be able to l
