George, looking at the schematic, the az/el signals from the rotor pots feed
4 op amps. Two of the op amps feed the front panel meters, the other two op
amps feed the din connector the LVB Tracker is plugged in to. Since the LVB
Tracker is reading correctly and the Azimuth meter reads ok the problem with
the elevation meter is either the meter itself or the op amp circuit that
drives it. You?ll hafta do some signal tracing... Good Luck?

The LVB Tracker shows correct Azimuth and Elevation angles and the G-5500
rotator follows the correct angles.? However, the Elevation meter of G-5500
remains at zero degree.? The Azimuth meter works just fine.? Thanks. 73,

Hi!
I've had Astron switching power supplies for many years. If they
give off any RF noise/interference, I don't see it on ham bands.
They are quiet. I also have a Powerwerx SS-30DV switching power
supply for operating away from home. The Powerwerx unit is small,
and also has been quiet when used with my ham gear. The only thing
you have to do with the Powerwerx units is to make sure the AC
voltage is properly set on the back - they are normally set for
220V out of the box.
73!

At the risk of sounding like "My dad is stronger than your dad", here's my
experience. I have two Astron Power Supplies which I bought in 1985. They
still work like champs.

Hi to all!
In my groundstation, i'm have orbitron to track the satellite, and
WISPDDE to interact with the rotor (Yaesu) and the transceiver (IC7100).
Reading the WispDDE software (from the source code that it's publicly
available), we use the template of IC-910 to command the equipment, but
acctually have a problem when we try to adjust dopler correction via
USB, for both VFOs. Aparently to adjust the frequency of the VFOB, need
first to put this VFO in the MAIN VFO.
It's there any way to adjust the frecuency via USB, for BOTH VFOs (A and
B), but mantain the MAIN VFO only for the VFO A? i cant find any
information in the equipment manual.
Thanks in advance.

Attempting to set up ISS voice frequencies on a Yaesu FT-847 using OmniRig
CAT control.
Enter 145.800 FM for RX and 144.490 FM for TX. Rig recognizes frequencies
when ISS is selected,
and tracks for doppler. When I push PTT, I get "ERROR" on the TX Frequency.
Any thoughts on how

Greeting All,
First of all, my hat is off to Casey KI7UNJ and Jonathan KI7BEX for
freezing their tails off in order to bring us a bunch of rare grids from
BLM land in Nevada, thanks guys!!!
Dmitri N6DNM emailed me that he couldn't confirm our satellite QSO on
QRZ, even though all the data seemed to be correct. I have noticed this
as well, that none of my satellite QSOs? have been confirmed on QRZ
either. We both uploaded our contact information via TQSL, filling all
the information including transmit and receive bands and frequencies and
then loaded it up to LoTW.? I also use the specific frequency at the
middle of the passband, for example, 435.350? and 145.880 for AO-92. I
also save the adif file, naming it for the specific satellite and then
upload it to QRZ.com and my HRD logbook. Why aren't my satellite QSOs
getting confirmed on QRZ?
Thanks for your help.

Loon,
The 847 can?t handle the same band in both VFOs when in Sat mode. Your best
bet is to use SPLIT with Sat mode off. This is what I?ve been doing for ISS
packet with reasonable success.

Looking forward to the IC 9700- I just put my CC in after having a
reservation at DXE for nearly two years!
Going to use a 70Ah AGM to run mine. It is charged with an Icom 126 PS via a
West Mtn Radio Epic PwrGate. It is very quiet, but if it does become a
problem, I can just turn it off temporarily.
I do have a 35amp Pyramid linear supply which is very RF quiet, but weighs a
ton and takes a lot of valuable space in my shack. So it?s for sale.
