[digitalradio] Re: packet not listening fast enough?
Thats what I was thinking... I did manage to fix the issue though by swapping radios - I am using my mobile Kenwood 2550A instead of the HT and it works fine now. At some point I will probably try to track down the issue with using the HT using both of your advice, thank you! > Wouldn't it be an issue with a too short TXDELAY on the other side, > coupled with a too long state machine sync on your side? > > It was an issue when I had a to short TXDELAY, some had fast enough > radios, others did not.

[digitalradio] packet not listening fast enough?
Can someone tell me if this makes sense -- I had a RS 2m HT with a KPC-3 and was able to reasonably connect to 3 different stations. I switched out the radio and put in a Kenwood TR 2600 HT. It is lower power (2.5 vs. 5 watts), but those stations still seem to be able to hear me, and I can still connect to two of them without issue. However, the third one when I connect to it sends me a message back that I am connected to it, but my KPC-3 does not recognize the connection and eventually times out retries. Listening to it, the difference that I hear is that station seems to respond very quickly. I am wondering if something is getting cut off, or I need to adjust something int he KPC-3 to tell it to start listening sooner or stop transmitting as long...? Any ideas?
[digitalradio] squelch issue
I know this is not digital specific, but I am hoping someone can point me in the right direction - I have a Kenwood TR-2550A mobile radio I purchased used that I am using for APRS. It worked well at first, but I think it now has an issue with the squelch. It transmits fine and receives fine if I test with my 5w portable HT. However it is not picking up weaker, further away transmissions that I can hear on the HT. The HT is using a rubber duck antenna, the Kenwood has an apprx 3' omni in the attic. The squelch knob did not seem to work when I received the radio, but I was receiving stations, so I didn't care. What do you think I should look at, or can you point me at some places more appropriate to ask this question? Thanks! Scott N1VAN
[digitalradio] xastir or similar service/daemon 'back end' software?
Is it possible to run xastir (or some other similar aprs software service) on a machine as a service/daemon, and use a different machine to connect to it to view aprs maps? I have an old very slow machine that should be good enough to do the communications and data manipulation, but it is way too slow to view the maps once they are loaded in. (300mhz, 256mb ram) Thanks!
[digitalradio] Re: source of 8 pin female radio connectors?
I found a good source, my local Radio Shack! About $1 higher than ordering online, but no shipping costs...

I thought of digikey or mouser, but what is the generic electronic part name for it?
[digitalradio] source of 8 pin female radio connectors?
I have a aea pk-88 tnc and a kenwood radio, they both have the same 8 pin male connector, so I need to buy some female 8 pin connectors and wire it up. Know of any good cheap sources (online) or in MA?
