[Lowfer] WG2XNI DFCW60 186.109 khz tonight

[Mark]

Thanks everyone for all the reports, esp those who left their grabbers on 
last night, it was interesting to see how the sig changed throughout the 
evening.

I reviewed my reception reports of MBD from last year and compared with 
those of XNI, and as expected the XNI captures have been much 
better....although not as good as I had hoped for ( I thought I should be 
copyable at QRS3 or perhaps even audible under good condx) I have been 
pretty happy with the results.  I've had captures from coast-to-coast this 
year, something I was never able to achieve with the lowfer power.

Previously have been ruuning XNI at about 70W ouput ( at ~ 70% eff ), and 
made some tx mods last week to increase efficiency to around 90% and 100 W 
output.  I'm approaching about 1.25A of antenna current now, and if we have 
a cold snap it will go higher !

The antenna is very simple,  perhaps 30' vertical wire with two short ( 
maybe 7 or 8' ) top hat radials and another long 30' top hat radial.  It is 
only a few feet from the side of the house.  So I imagine my antenna 
efficiency is quite poor compared to most of the lowfer antennas around ( 
and the stns on 137 khz ).
