My signal not decoded

 

Dear all
I am using IC9700 radio with Gpredict with rig control?for APRS decoding?in ISS satellite passes. I am using?UISS software and UZ7HO sound modem. Also using APRSE32?software.?
In the sound modem settings,? I am using usb?audio?codec as input device and output device.? When I send a text message my message is not decoded and not hearing?my tx signals. But I am getting?rx . I have checked the radio settings and uiss settings and sound modem settings with one of my friends whose signals are decoded. I could not find any issue. Can anyone suggest a solution.

I am sure there will be an answer out there Balu, due to the holidays the answer may be slower than usual
in this group, you may want to add any additional things that may help, I read recently that a recent Windows update may?
broken USB connections, so your pc and version of windows may be a help or whatever configuration you are using

Balu,
When you say " ... When I send a text message my message is not decoded and not hearing?my tx signals."
??? Does the Radio go into TX? Or, is there just no audio coming out of the sound card.

Probably the most common problems with TX not being decoded are:
1. VHF radio is in REPEATER mode and so the TX frequency changes on PTT.
??? Watch the radio display when you send a packet to make sure the frequency doesn't change.
??? Satellite radios may even TX on a different band.
??? TEST: Plug in the mic and press PTT.? Watch the frequency display to make sure it sends on the expected frequency.
2. Sound card audio too LOW or too HIGH (either can cause problems).
??? TEST A: Connect the USB sound card to a speaker (if available) and make sure that there is audio coming out.??
??? TEST B: Another option is another radio (receiver) tuned to the TX frequency and listen to make sure it sounds correct.
3. PTT not working through UZ7HO
??? TEST: watch the TX LED when UZ7HO puts the radio goes in TX mode.
?????????????? If #1worked, this checks the UZ7HO interface.
??? REMEMBER:? only use 1 method of PTT.? Don't enable digital (like RTS on a serial port) "AND" CAT control.
??? Personally, for packet I prefer toggling a pin for PTT, but I know you have GPredict running and it may have CAT PTT enabled.
4. If everything looks good, but still no luck, try transmitting on the APRS frequency to see if your signal gets decoded.? There are a lot more stations out the listening.

Balu,

Are you saying that your transmitted data is not displayed in the soundmodem window like your received data. If that is the case then Soundmodem does not display your transmitted data in the window. If you have the waterfall enabled you can see traces when you are transmitting as well as other? signals on the band. If you want to use the PTT from Soundmodem then you have to download the PTTdll.zip from UZ7HO and unzip it in the folder with Soundmodem. Soundmodem will then pick it up and use it.? If you have a HT tune it to your transmitted frequency and sit it near your radio. You should hear the buzzes and beeps of you signal it your radio is transmitting.

Good Luck & 73, John N5TIM

I've been experimenting with both SoundModem and Direwolf.? Sometimes I fail to keep track of Ackmode vs. NORMAL.? Worth a check.?

How do you know your signal is not decoded?
