Another Digipeater - Not receiving stations


 

I am attempting to setup a portable Fill-in Digipeater.? I am using a 12v battery, TT4, and Radio Shack HTX-252 connected using the Byonics cable, R4C.? Pretty basic setup.? The problem I am running into, is unless the signal is really, really strong, the TT4 isnt decoding it, or even seeing the carrier (no lights).? I have two other aprs stations at my location to compare, and would expect simlar results.? (mobilinkd / FTM-3100) & (direwolf / IC-7100).

I have adjusted RXAMP to almost every setting and used MONITOR while adjusting volume, forcing other APRS stations to trasmit, and just getting poor results.? I have also run a "RESTORE", and reconfigured the system, messed around with CDMODE and CDLEVEL.? I have plugged external speakers into the audio port of the radio to verify it is working and I can hear signals.? Turned squetch on, turned it off, added ferrite cores to the audio cables.? Yes, I have an anetnna plugged in, even gets 1.1 SWR. ?

As another test, that I didn't spend much time on, was to plug the audio cable into my IC-51 handheld, to make sure it wasn't a radio issue, as this HTX is an ebay find. ?

I have attached my export config.? (Dropped BANK1 config as it was just a copied and reduced the size of the post.)? Yes, it is a bit simple right now as it is just focused on receiving signal before I start configuing everything else on it.? ?

I also included a receive log below.? My station comes through, but is close to 30 feet away running 5W.? The other station is a few miles away, but have no idea on setup or power output.?? Being just north of the Seattle area, this area sees a lot more traffic as I am able to see on my other stations. ?

Any insight into what I may not have tried or what I may be doing wrong, would be helpful. ?

Side note, I am running verison 0.72

Greetings,
The Radio Shack HTX-252 has never worked well in Packet because of an audio "twist" the radio produces. Had many people try to use them, only to swap out the radio for an ICOM or other rig and the problem disappears.

Sorry to bring you that bad news...

Are you running the HTX with open squelch? If not, I suggest?doing so, since the Squelch will clip the beginning of packets, making them effectively unreadable. I also strongly?suggest setting the audio volume on the radio as low as possible, as audio distortion increases faster than volume, complicating the decoding of packets. Leave the CDLEVEL?at the default, but set the CDMODE to TONES. Try the RXAMP?at the default, but back it off slowly until you can decode packets. You will always be able to hear packets you can't decode, don't worry about that. It's also very possible that your RS radio is just deaf.

Well that is not what I wanted to hear.? I will setup my station on my FTM3100, which works great and see if that resolves the problem.? Then I will know what I have to do.? Thanks for the quick feedback.


 

Looks like the HTX-252 was the problem.? Moved the TT4 over to a couple other radios I have for a temp test, and now I am seeing the Carrier Detect light to light up, and am able to decode many more stations.? Thank you.? Going to review a replacement radio now.?

Thanks.
