Roger, Alan & Jack:  Thank you for the information. It could be my Internet 
provider or some other
unknown variable sending my e-mails occasionally  to the same parallel 
universe location where my missing laundry socks must be hiding ~:)
(Very) good to know there was no underlying netiquette issue.

 BTW I have been running the FT-817 for the past 2 days on 2200m with only a 
300 kHz LPF in front of the
2N3904 broadhand preamplifier and some input attenuation in the radio. The 
results have been very encouraging.
Tonight it seems quiet enough on 2200m band that I am able to turn off the 
attenuator in the FT-817 and use an
external 3dB stick attenuator without excessive S meter readings.  About an 
hour ago I replaced the 3dB pad with
 a 137 kHz band pass filter with insertion loss in the 2~3 dB range and I 
see my background waterfall color slightly
 deeper blue color as a result.  This direct LF rx with the FT-817 is all 
very encouraging so I have to thank G3XBM
 for igniting a spark of interest with  his 2200m voltage probe antenna to 
FT-817 postings...

Cheers & 73, Mike wa3tts
