Ok. Yes Sorry was typing my phone. Yes I was talking about SSB. I have an HF all mode, but don't have 2 meter or 70 cm on that radio. I have a couple FM baofengs HT's. So guess I use them for SO-50. Ive been doing some reading and thinking of getting a USB dongle. Ive been reading on the funcube dongles, but not in my budget right not, but was looking at these cheap dongles. Will they work for AO-73 and other satellites?

Todd,
If you were meaning to type SSB for the type of signals transmitted from AO-73, then yes - you will need a radio capable of SSB reception to copy anything from AO-73 - telemetry or transponder. If you have access to a Kenwood TH-F6A HT, this radio has an all-mode receiver which may be sufficient for copying the telemetry and the transponder from AO-73. For the telemetry, you would patch the speaker audio from the radio into the mic jack on a PC running the FUNcube Dashboard software from the www.funcube.org.uk web site, and set the radio around 145.935 MHz USB (probably start closer to 145.938 MHz at the start of a pass, and end up around 145.932 MHz near the end of the pass). Make sure the radio you use has small tuning steps, and be ready to tune down during the pass.
The daytime passes are the easiest to copy telemetry, as the transponder is off at that time. The telemetry is still on at night, but at 1/10 the power level that is used for the daytime passes (30mW downlink at night, compared to 300mW in daylight) to allow for the transponder to operate. The transponder transmits at 300mW across its 20 kHz passband, betwen 145.950 and 145.970 MHz - use USB for best performance when listening to the transponder. You can see some slideshow videos of me working the AO-73 transponder, using different radios as the receiver, on my YouTube channel:
Hope that helps. 73!

Some of the cheap DVB dongles will definitely work to receive the telemetry from AO-73. You will probably be able to hear conversations on the transponder in the evening too depending on your antenna. AO-73 has a strong signal. You will probably be able to hear the transponder downlink from VO-52 as well.
Check out N4JTC's blog post about how to do it:

Is the Auburn Sat operational?
Are the KEPS in the Celtex? What is it's number.
Just worked W1AW/2 FM 30 on SO 50 Pass.
The new K4AMG circular M2 antennas and AR2 SW Preamps are working great.
Will be on other birds this weekend as time permits.
God Bless

What have I done wrong? Trying different options I have loss multi sat views. The M button says plus but only one selected sat shows at a time. What did I goof up?

Hi Rich,
Check your satellites list to be sure that you have all the ones you want set for "Show On/Off (it puts an asterisk next to them when Show is on).

If it is a favorable pass K4AMG will be on AO73 this morning at 1420 UTC
So far only 1 QSO KB3M. Maybe one of you will be on. I will be about center about .960 freq SSB
This will complete our test of new antenna system on all linear trasnponder birds and SO 50.
God Bless

Okay guys
Thanks.
Some how I thought the linear transponder was on days on the weekend.
I did hear the data transmission, said to say, I did not know how to tune it on my PSK 31 program. It was very stong. Think it is SSB.
One day I will get it right!
Thanks all.

Download the FUNcube Dashboard to decode the telemetry. It is a SSB transmission.
http://funcube.org.uk/working-documents/funcube-telemetry-dashboard/
At times, the control ops in the UK may command the linear transponder on for daytime passes on the weekends, but they have not done that yet. It has been in it's autonomous mode, which is telemetry only while in the sun and transponder while eclipsed.
