[Lowfer] WM et al

".....show that the frequency positions of the W and the M have 
reversed."
Gary and other interested Lowfers,

Yes, that's on my to-do list, Garry. Currently I have no way of insuring which of the two characters comes first with its larger size and offset compared to the second character. So it's either Wm or Mw that you see. There are two digital counters that divide by 2 and divide by 5 that generate the square wave sequence fed to the integrator to form the characters. I think I can simply add a reset button to force the Wm sequence every time.

On the antenna experiments: I just lowered the loading coil back to its original position next to the counterpoise and find the antenna current is, again, higher than it was at the mid-position. I'm about to check the signal strength at one of my reference locations here in Plymouth, NH, to see if the signal strength is also higher... and this should be interesting.

It was rather noisy at the start last night but lowfer BR on 185.575 kHz 
at 0430Z and MP and NA on 137 kHz at 0600Z came through decently. The 
watering hole was checked several times and WM was noted but only traces 
of WMS were seen. Generally a small loop antenna was used to reduce 
overload from local SIW (the heading to WM is nearly orthogonal to the 
SIW heading). That generally precludes seeing both WM and WMS 
simultaneously but last night there were times when WM came through 
while aimed at WMS and seeing only traces of WMS. Comparison of last 
night's WM waveforms (left side of attachment, taken at 1200Z and 
showing sunrise dropout) to those taken Jan 5, 2012 (right side of 
attachment) show that the frequency positions of the W and the M have 
reversed.
