Need some advice.
Can I do this with the ICOM 910 ?
1. Run ISS independantly on VFOA with a 1200 baud TNC. (and TX) 2. Run GO-32 / AO-51 on the sub band (RX only) 9k6 - WITH an AG-35 preamp in line ?
From what I am reading, the AG-35 or AG-25 for that matter, are powered up
the coax ??
I have a KPC9612 TNC with seperate 1200 9k6 ports.
That should work out nicely

Hi Andrew.
If you only want to RX on both ports, no problem I would of thought.
One problem, perhaps though; I believe you can only choose either 9K6 or 1K2 through the ports on the back of the 910.
You would have to take audio from the Ext spkr socket on the back for 1K2 on VHF and set the RX on UHF for 9K6 reception.
Usually, you have to request files and list directories from the 9K6 birds, if you want to make any sense of what's on them.
You could use UISS for VHF ISS reception, but you will need WiSP or PB/PG for decoding 9K6 data on GO-32 and or AO-51.
The AG25 and or AG35 will work independently. You will not need the pre-amp for ISS reception. A mast head pre-amp is useful for 9K6 reception.
You will have to select the pre-amp to operate from the 910 menu and then push the appropriate button on the radio.
I use a DSP2232, so no experience of the KPC9612.
Anyone else with an alternative ?
73, Dave.
What I found with my ICOM 706 is that it has one data port.
That data port, has two receive paths,
1. Striaght audio limited for a AFSK 1200 baud TNC 2. A second port that can be toggled as 9k6 (disc) and 1k2 (audio)
From what I can gather, and am hoping is that the ICOM 910 does the same
thing.
Two independant data sockets, setting the menu to 9k6 makes the '9k6' pins on both data sockets '9k6'
And regardless, the audio out or 1k2 port would remain the same.

I think I read the manual wrong.
The 9600 baud menu option is for TX.
But what has me confused now, is setting this to 1200, does it do what my icom 706 does, and affect the rx 9600 pin ?
I think what I have to do is
1. Set the 9600 baud option to "OFF" in the menu (this is only for TX) 2. Then 9k6 and 1k2 data will be available as normal from the 9k6 and 1k2 pins on the data sockets.
This would allow me to tx and rx 1200 baud on VHF (ISS), and rx only 9600 baud on the go32 and ao51.

I just found something interesting,
The main data jack has all the functions - PTT etx The sub data jack only has rx only

Hi Andrew.
I don't use the "satellite" mode on the 910, but I believe that if you do, the sub band does transmit. You will have to check that for yourself.
Let me explain my own method for what you are trying to achieve.
I use WISP, by Chris Jackson G7UPN. It works very well, and is the only software, apart from PB/PG, that can be used to talk to the 9K6 satellites. You have to be able to uplink to request directories and subsequently, independently, download and read the files of your choice. If you don't do this, you may not receive complete files, which may also be compressed/zipped. There are lots of other files created on the satellite that are of no use to us, the basic user.
My 910 is permanently in 9K6, it shows on the display all the time. The figures 9600 have to be in the display. This means that I can upload files, request the directory and download files from GO-32 and AO-51.
Even in 9K6 mode, although not transmitting, I can still monitor the TLM/KSS files from AO-16 and the packet from the ISS.
For the above, all I do is put a cable in the extension speaker socket at the back of the 910 and the other end in to the TNC, an AEA DSP2232.
If you wanted to uplink to the ISS, you may have to change from 9600 to 1200 in the display. The best software for that purpose is UISS, written by Guy, ON6MU.
Remember to remove the audio jack used for 1K2 reception, from the 910 so that you can receive 9K6 data again.
If you are considering tracking with azimuth and elevation equipment, I can highly recommend HalloSat, written by Gerd, DB3DH.
All the above works for me, so it should do the same for you too. The only difference is our TNCs.
I hope the information is getting a little bit clearer for you Andrew.
73, Dave.
IC-910 Arrived today
Man - nice radio
Sorry to my old ft-736, but a new car is in the garage.

Hi Andrew, Congratulations on the new radio! I'll be interested to hear your impressions of it as I'm pretty sure it's going to be my next radio as soon as I can swing it. I used to have a TS-2000X that I had to sell. I can't quite afford another one of those and just think I'll try something different this time. The only other radio I've been looking at is the FT-847 because it has HF too but they are somewhat hard to find and I'm a bit leery of used equipment. 73, Michael, W4HIJ ----- Original Message ----- From: "Andrew Rich" [email protected] To: "Dave Aitch" [email protected] Cc: [email protected] Sent: Thursday, January 10, 2008 5:14 AM Subject: [amsat-bb] Re: ICOM 910
