I just joined this group and did a search on "Pegasus" and found your
post. What a coincidence that I was perusing the bands with Multipsk
and found you in a QSO with NU4M using MFSK16!
I just bought my Peg a couple weeks ago and it has taken over my life.
I was looking for software that would let me key the rig via software
and I think you gave me the anwer here with the mention of the DX Lab
Suite. I looked at Commander but it seemed to be saying that I had
to be running other control software like TenTec's or N4PY's to work
with it. That's OK I have both of those. So I'll go back to that
and see if it will send key down/up commands to the Peg from Multipsk.
Anyway thanks for the tips on the software and the ALC. I was using
the same method of tuning up with another rig, my FT-767GX and
thought the signal sounded clean even tho I was getting the light.
Hope to read you on 10.136 agn, maybe you'll be able to hear me too,
I'm pretty antenna challenged here on the 5th floor of my apartment
building. I went out at midnite and dropped a 35ft length of magnet
wire out the window and tied it to a small tree with a piece of
plastic fishing line. Works better than anything I had tried inside
the apartment. Tunes from 10 to 40 meters. But a good stiff breeze
might snap it any time and I'll have to make another midnite run. Oh
well I've got 500ft of the magnet wire.
