[Lowfer] Lowfer SIW QRV

[Garry Hess]

With help of Bob, NK9M we got lowfer SIW running again from EN51uq. The 
schedule is still 185.2993 kHz QRSS30/60 on M,W,F and 185.185... kHz 
slash code on T,Th,Sa,Su. Switching time is 1800Z.

Last season the slash code dashes bottomed out prematurely and I thought 
that might be because one op amp was running unregulated. Now all op 
amps are regulated and despite good behavior on the bench both dits and 
dahs are crimped in the field. So much for progress! Maybe next year 
I'll program a Raspberry2 uP to do the job and get rid of those touchy 
op amps (especially so when one runs them off a single supply). The 
symbol period has been increased to 5 minutes so it takes quite awhile 
to send "SIW".

Hope the watering hole has more company by the time LF reception gets 
really good. I'm already decoded Newfoundland on 288 kHz and Maine on 
316 kHz DGPS tonight. NDB DF in Newfoundland on 350 kHz is also doing 
well. A good sign.
