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

Hi Jacek on my own checks it seems to be posters out side the UK who
occasionally have trouble ( some ISPs are permanently locked out it
seems). I also noticed on the turn of the year there are a lot of sites
whose certificates have expired. The checking is set fairly tight I
believe, and sometimes messages are dumped. There is an interesting bug
where if you send an attachment but leave the subject field empty the
parser throws a wobbly and the attachment and message get corrupted.
Even more interesting is that it is still alive because 'there was no
archive that could be harvested' .... that is obviously no longer the
case.
It is generally surprisingly stable. Even more interesting I cant get a
sensible response from Yahoo groups at the moment :-))
