Gonna take up some more CQ-Contest bandwidth. Sorry Trey.
I have noticed several 160m Internet mailing list subscription requests

Here is the reply I got from MCI about lost mail:

Doug,
I checked with MCI Tech Support and they confirmed that there were
delays with message deliveries through the Internet gateway
from 1-30-95 to 2-1-95.
When sending to people who are on MCI Mail, go directly, and not through
Internet.
Take Care,
Carol

By the way, the DELAY was infinite (aka:lost)

Hello Gang!
Boy, can sure tell the stopper was pulled out at the dx reflector!
Getting LOTS of replys to my "is anyone getting this" query sent
many days ago. Thanks all! But those via the dx reflector (still)
missing headers. Use those e-mail address signatures, guys.
My warning about the FT-1000 relates to the external antenna (phono)
jack that is selected by the front panel's RX ANT switch ... IT IS NOT
PROTECTED and severe damage can be done to the antenna input circuitry
and the PC board of the FT-1000's RF BOARD if this jack is subjected
to high levels of RF. What's "high"? ... dunno ... sad tale follows:
I have a dedicated, insulated, top loaded 70' tower with 120 radials
for 80/160M. Nearby (about 20' and end-on) is a 135' C/F Zepp that
is tuned to 80M by a Matchbox. A run of Phillystran ties one end of
the Zepp to the tower ... not an uncommon situation.
I've used an outdoor 6' loop (with built-in preamp) on 160M for many
years and on several different rigs. An interest in finishing off
5BDXCC with a few more countries on 80M led me to try the 80M Zepp
as a receiving antenna and so connected it to the FT-1000's RX ANT
input. It worked as expected ... "quieter" than the tower.
Tuned up the amplifier to 1.5 KW and -immediately- smelled smoke!
Traced the smell to the FT-1000 and was dismayed to find it essentially
dead on all bands. My first thought was that something had failed in
the antenna relay circuit of the amp, but not so. Took the rig to the
bench and as soon as pulled off the botton cover saw the little black
spots on the PC board where components used to be. Enough to make a
guy say; "Shucks!"
Connected a Bird (50W HF element) and dummy load to the cable from the
Matchbox that had fed the RX ANT input and keyed the amp again ... the
meter gently gently pegged at 50+ watts!
The loop's preamp had taken the pounding from 1.5 KW on 160 for years,
and of course had protected the various receiver's inputs from damage.
I caution those of you who may use or be thinking of using any sort of
passive (un-amplified) antennas for receiving to do so with care. I'll
be building #49 lamp (60 mA) and 1/100 amp fuse boxes for both the FT-1000
and the FT-990, AND measuring RF levels before I try this scheme again.
I would think that there must be others out there, at multi stations
for example, who have been "burned" by this "gotcha!" ... surely, I'm
not the only one?
Oh ... the input to the FT-1000's BPF filter IS PROTECTED and (in theory)
can be used as an auxillary RX input in the presence of strong transmitted
signals ... with it's frequency-range limitations, of course ... but the
second receiver's performance is terrible ... yes, I have the 600 HZ
filter.
Talked with Chip at Yaesu and arranged to send just the board for
repair ... expected to have to buy complete board ... came back in about
four weeks ... so "pretty" thought they had tossed the old board and sent
new one ... but it was mine. The workmanship was EXCELLENT ... hard to
tell where the damage was ... and the cost was only about $70 ... I'm
IMPRESSED!
73! de Ken Kopp/K0PP
