Hi,
I am trying to transmit APRS packets from a Radiometrix HX1 transmitter.
And I am trying to receive the packets on my Kenwood TH-D7 (I know the D7 works because I've checked it with another transmitter)
However, no packets are getting through.
I have tried the following things already:
1. Connected the SP out of the D7 to my computer's sound card to check the received audio waveform. This looks *horribly* distorted, and bears almost no resemblance to the beautiful audio waveform that I know is going into the HX1. Sometimes I see a *very* low amplitude signal which might or might not look like the original APRS audio.
2. Tried to receive the packet on a Funcube Dongle. This time the waveform seems to be a constant 15kHz.
Has anyone else had this working? How can I go about debugging this?
Many thanks
Hugo
