Hi Alan:

Yep..I do alot of digital site recording of classical music using off-board A/D boxes. I can tell you that, even great laptops have really BAD sound handling ability. The stock AC97 system can be very noisy and I'm sure that would play havoc with 9K6. An option for getting the sound card to work is to let 2 computers talk to one another via their sound cards. I did this early on learning the 1200 baud system and it at least verifies most of the system without using up prime "pass" time.

You at least have the data ports on your radio--mine are just plain old mobil FM rigs so they might never work.

Thanks

Curt

Curt, I appear to be encountering similar results as you. 1K2 - excellent, 9K6 N/G

I continue to experiment with little success using Packet Engine Pro, UISS , sound card and FT847. The FT847 has 2 options - a data IN/OUT jack and a PKT 1200/9600 mini-din port. The 3rd is the external speaker and Mic jacks which I ignore as an option. Further, I've used 2 methods to interface the radio and sound card.

• SignaLink SL1+ to isolate the PC sound card from the radio PKT 9k6 port
• other times a direct connect between the sound card Mic IN/audio Out and

the radio data In/Out

So 2 ways to interface to 2 different radio in/out connections with rather short passes to fiddle with audio levels on the RX side to get a decoded signal and on the TX side to trigger a PTT.

Any combination of the above works wonderfully at 1K2

A further complication is the unknown viability of the sound card to handle the 9K6 well enough to not distort packets and allow the software to decode the packets. For now I'm using a Dell notebook. In a few days I may revert to a desktop where I can try various sound cards including the one on the motherboard.

The net result of this 9K6 experimenting is frustration and reversion to the goode olde PacComm NB96 that works every time and all the time with any dumb terminal program, stays hardwired so I can check for the resurrection of GO-32 and is one button push away from 1K2 operation using Wisp32, UI-View, WinPack or whatever. UI-View, WinPack and UISS work with AGWPE. UI-View, WinPack and Wisp32 work with regular comports or USB virtual comports.

I hate the idea that with today's fast processors that we have to revert to a hardware solution ( TNC ) instead of a "all software solution". But I don't mind continuing with this experiment. We're facing a long cold winter in EN19 and the shack is nice and warm and the rotator hasn't frozen up yet :-)

What kind of interface are people using between the radio and AGWPE?? I've tried my standard soundcard isolation unit but it doesnt seem to send decodable packets and receives nothing from ISS even though I can hear the signals well.

If the transformers are a problem in the isolation method, what is the alternative?

I too use UISS and AGWPE for 1200 just fine.

Anyone using the 910 on the VHF port for full duplex 9K6 operation with the ISS ?

I use a DSP2232, and of course, the upper part of the 910 does the transmitting and the lower for receiving, as with GO-32 9K6.

The hardware/software I use is HALLOSAT by DB3DH, for rotator and radio control.

I'm using UISS for decoding/displaying.

Is anyone using the IC-7000 and a KPC9612+ for 9.6k? I could sure use help in transmit settings. It receives good and keys the radio via port 2 on the tnc. The XMITLVL setting are currently at: XMITLVL 100/45. I have jumper J-20 in the default 'ON' position. CD is set at CD SOFTWARE/INTERNAL. I had to change from the default INTERNAL to SOFTWARE on port 1, but port 2 does not need to be to receive? I am wired using the six pin DIN on the back of the radio.

It works fine on port 1 (1.2k) with the 100 setting. I have tried port 2 settings from 1-65 with no luck. 9.6 packets are not being decoded. I don't have access to a service monitor. If someone could point out where I am messing up it would be appreciated.

Curt, I have a similar problem at my qth occuring at 145.801 MHz. I've had bigger fish to fry and haven't run it down yet. Dave Sent via BlackBerry from T-Mobile

I am seeing a very strong, full quieting carrier on 145.825. It appears to be external to my house since it is fully directional using the rotator. I expect it might be a fair distance away since it becomes in audible off the back of the beam. (6 el cheap yagi)

Anyone suggest any commonly found sources at that freq?

Its not my router, I turn that off--and it is pretty weak anyway.

Thanks
