I’ve heard a lot of people sing the praises of C4FM’s audio quality, but I don’t hear it. It’s clear, sure, but it’s also warblely and sounds like a robot trying to impersonate a person’s voice. Like the old Macintosh text to speech program from the 90’s.

I’m on a Wires-X net right now and some hams I know are checking in, I can kinda recognize their voice but takes me a minute.

#FT70D #HamRadio problem:

I bought the CT-44 cable, and tried to use it in conjunction with one of my BTECH #APRS cables. This works fine with other, kenwood-styled radios for APRS.

Even when I hold the PTT, the FT70 doesn't transmit anything from APRSdroid.

Being the curious type, I plugged in a cheap earbud mic. The PTT button on the mic triggers the PTT in the FT70 but the audio doesn't come through.

Is my FT70 broken? If so, that's sad, I only got it in October.
