[Lowfer] LF: TXing 2200m WSPR

After nearly 10 months of planning and work, I am able to make my 
first transmissions on LF! I am running 10 watts from the 
transmitter. EIRP is a bit less than the claimed 0.1 watt.

I am having some difficulty which I do not yet understand. It could 
be the antenna (arcing), the coax, the amplifier (oscillating), the 
scopematch (lying) or some combination of these things. :)

I can say that I do not trust the little amplifier. Mine clearly 
does not behave as the designer says it should, so it is suspect.

I will leave WSPR running tonight for as long as things remain 
acceptably stable at this power level. I have a CW ID at the end of 
each WSPR transmission. If anyone can hear the CW, please let me know!

73,
