[arm-allstar] TX time out

[Doug Crompton]

Matt,

  Very good, I will take a look at your photos. It is always a good idea to put a fan on Allstar nodes as the talks came sometimes get very long. I know they do on my hub. Most radios including Motorolas need additional cooling.

Thanks Doug. I'll connect 
it back up and keep an eye on it to see how it goes.



I have the whole lot rack mounted on a 19" shelf with it's own PSU. Was 
thinking about adding a small fan to help cool the radio down but it 
doesn't get to hot at the moment. Pictures and details on my website at www.m0lmk.co.uk/mb7ibk



Thanks,



Matt

Matt,

 It is a pretty rare occurrence 
for this to happen without the disconnect conditions I pointed out. I 
suppose there could be some instability in your system due to other 
things. The number one problem is power supply issues but that to is 
also rare. Also outside RF sources such as Higher power HF or VHF/UHF. 
These frequencies can couple into long leads. Using ferrite chokes on 
all leads has helped.

It also could be the radio. Malfunctioning 
there could cause the COS output signal to hang. 

There is no log
 entry that would tell you anything other than COS was asserted which 
you of course already would know. If it was external from an external 
source Allstar would have no knowledge of whether it was truly a valid 
COS or not.

  Hi all.



My node got booted off from one of the allstar hubs today because it
 was 
stuck in constant TX. Is there a setting to prevent this?



Thanks,



Matt
