[time-nuts] FMT

[Didier Juges]

Hi Connie,

My life has been a little complicated lately, but it will settle
eventually :-)

I was surprised to be so close just by ear. 20m was hard because of QSB,
but 40 and 80 were good, with strong and stable signals.

I have Spectrum Lab installed on this "new to me" laptop, so next week
should be better. I will use the HP 8657B instead of the HP 3586 (the
lack of attenuator on the 3586 TG output makes it hard to adjust the
level of the injection signal). Resolution drops to 1 Hz instead of 0.1
Hz, but with Spectrum Lab, that should be fine.

Thanks for running this exercise. That is most interesting. I wish ARRL
had such a good setup...

73,
Didier KO4BB

Hi Didier,

Good to hear from you. Sounds like you did fine considering how bad
condx
were that night.

I will send out an email on the time and frequency. I think it will be
Thursday night this week, but not sure yet.

Thanks for participating and have a good weekend

Well, I was too late sending my results, but I did manage to listen to
the signals this past Wednesday.

I did not have time to prepare anything but listening by ear on the
FT-1000 and using the HP-3586A as a beat generator (free running off
it's internal Ovenair precision OCXO), I managed to get within 0.4 Hz on
40 m and 0.2 Hz on 80m (good signals). I was off by 1.5 Hz on 20m, where
the signal was very weak with QSB, and I did not hear anything on 17m.

Thanks Connie, I will try to be better prepared next week (hooked to GPS
and using Spectrum Lab).
