Hi Folks -

Has there been any news on what might have happened to FO-29?

It's a wonderful resource, and I'm hoping it can be brought back into service.

Fingers crossed,

Carl,
The parameter REV / NOR in Doppler.SQF has only meaning for linear Sats:
If the user tunes? the downlink frequency, the program changes the
uplink frequency either in the opposite direction (REV)? pr in the same
(NOR). The REV setting is correct for almost all linear satellites, only
a few require NOR, e.g. AO-07, Mode A.

With FM satellites which operate in fixed channels, the setting is
irrelevant. Also, the REV/NOR paramater does not affect the Doppler
shift correction. Uplink and Downlink must alway be corrected in the
opposite direction The program also does not change the REV / NOR
setting of the radio. But it overwrites the frequencies set with the
VFO. If you change e.g. at AO-73 both frequencies with the VFO up by 10
KHz, the uplink gets wrong by 20 KHz. Therefore, the program changes the
uplink down by 20 KHz.


Try Jeffs, KB2M, entry in Doppler.SQF. If you don't hear signals from
other stations change the downlink using the 'Downlink' correction
controls in menu 'CAT'- First click the control 'V' (which is 'V-' by
default with FM sats) to V+. Then the controls will work also with FM
sats.? If you hear other stations but not you own signal, correct the
uplink using the 'Upl. Corr.' controls in menu 'CAT' (control V must be V+)

If you know? the correct entries in Doppler.SQf? change the data line
manually and save the file.

What should the Doppler.sqf values be for AO-92 L-Band be? I'm having
issue with AO-92 L-Band uplink tracking on my IC-9700. I'm guessing it has something to do with the frequency trend (Nor/Rev) setting. I've tried it set to both Nor and Rev but for some odd reason the Nor/Rev setting does not make any difference and my uplink frequency keeps dropping during the pass when it should increase? I also noticed the IC-9700 display the NOR/REV never changes according to the what the .sqf is set. I'm not sure if this
is a CAT issue with the rig or me? I'm using the current IC-9700 firmware 1.11. Here is what my current .sqf is set:

AO-92,145880,1267350,FM,FM,NOR,0,0,Voice L/V

I got it to work once but manually selecting the REV on the 9700 display.
But then the very next pass it didn't work?? Any advice would be appreciated. Thanks.

Just a thought -- one of the benefits of using the actual call sign
(RS0ISS, PSAT, PSAT2) rather than ARISS or APRSAT is for the record.

For example, I am calculating the Az/El of each contact based on the
digipeated (PSAT*) path. When the digipeated path is ARISS or APRSAT there
is no good way to clarify which satellite participated in the packet.

http://www.spacecommunicator.club/igates/

See the Az/El columns for PSAT; I plan to add Az/El for others sometime
soon.

As a consumer of the data, I prefer seeing the individual call sign. As the user of the radio, I can see how using APRSAT for everything is more convenient.

Agreed, it's a pain to have to keep changing PATH, baud rate, and data
band between FalconSat-3 and the other packet satellites. At least there
are only two configurations to have to toggle between. Once you've done it
a couple dozen times, it becomes second nature.

Yes, PSAT2 (and apparently also AISAT) may need to use Narrow FM mode, but the mode can be easily programmed into memory channels. I just set up a different set of memory channels for PSAT2 and AISAT to set that mode and enable (crude) Doppler correction. I haven't used them yet so don't know if
5 kHz steps will cut it.

PSAT2 is also a different beast apparently. The text in the link imply

First bullet - Radios must be in Narrowband and track to 1 KHz Doppler on

The reason for asking is to be able to make as few changes to an HT (D72)

FalconSat-3 is a different beast: 9600 bps vs. 1200 bps, and crossband at different frequencies than the 1200 bps packet satellites. If you want to
be digipeated by FalconSat-3, you need to use the PFS3-1 PATH.

I have put together a rig for when I travel and have no room for an Arrow 2 antenna, which consists of a Kenwood TM-D710GA radio and a dual band, Comet, 5/8 wave whip antenna. This allows for a quick setup to work a bird from new grid squares, without disrupting the family. On our recent trip, this worked great for AO-91 and AO-92. However, I can't a signal from SO-50 with this
rig, even with a preamp. Does anybody else use this radio on SO-50 and would you have any suggestions? I know it is not an ideal situation, but it may be the "only game in town" for some trips.? Brad Smith, KC9UQR

SO-50 has a lower power output than AO-91 and AO-92, and it has a 70cm downlink, so the path loss is higher. You're gonna need a beam or
really high elevation passes to work SO-50. If you could get just a
70cm beam and use the whip to transmit on 2m, you might be able to
make it work. the 70cm elements might be small enough for travel too.

Personally I have traveled with my backpacker Arrow II on planes
without problems. Do you have the backpacker with split boom?

I place my Arrow II into a 3" diameter PVC pipe with end caps. I think it's
2 feet long. It stores well in the car trunk and the PVC is strong to
protect from bends or punctures.

Wyatt, AC0RA, has been know to operate with just a mobile on U/v

satellites.? On V/u satellites (FO-29 and SO-50), he uses a shorty arrow (4
UHF elements only) and a UHF preamplifier for downlink.?
I have tried operating with a mobile whip, and, yes, I could get into the
bird, but not consistently.? Having some form of directional antenna is
always better.
I have used both my shorty Arrow (2-elements on VHF and 4-elements on UHF)
as well as my baby Arrow?(1-element on VHF and 3-elements on UHF) with my?Kenwood TM-D710GA.? Aiming/polarization matching is more critical than
with a standard Arrow, but it still works a whole lot better than with just
a mobile whip.? Note:? I bump my power up to mid-level.

Actually, when you use ARISS or APRSAT then the signal comes down as
RS0ISS* if it went via ISS, and comes down as PSAT,ARISS* or PSAT2,ARISS*
if it went via one of those. Yes, it is a parsing pain, but a simple
rule. If you see ARISS*, then simply find the actual satellite in the
previous field.
