I understand, Scott - and I'm sure that all your potential buyers at Dayton would like to know that the units actually work as advertised, not that there is an...
... Sorry - missed this in the last post. No, the "digi-challenged" units are not completely deaf - they just appear to be randomly selective about what...
... This is exactly my experience with two different OT2m units. I have a third unit, but haven't had time to test it. I have tested with an OT1+ in KISS mode,...
Ok, anyone who's having a receive problem with the OT2m - can you please check the PCB lot number on the lower-right corner of the board, near the ACT LED?...
For what it's worth - I had problems at one point with a digi setup where it appeared that the TNC was deaf ... but the problem was that a nearby power supply...
I've listened the first of the audio captures (Milan) and there seems to be some sort of low-frequency pulse or flutter in there. I've extracted a sample...
I am running off a battery and still having the same problems. One thing I noticed on a scope was that the 1200Hz test tone from my MT300 was twice the...
Can the sample file "flutter.wav" be posted on the ftp site (my audio processing ability prefers direct file input -- I don't know how to capture the audio as...
That'll definitely kill the demodulator. The 2211 can't handle that much twist. Having the high tone higher doesn't matter as much. Is the MT300 transmitting...
That's a good point. I just shipped off a test unit to Elmer that fixes the problem in my testing, but it's a pretty major mod and I don't think it should be...
Done. I didn't notice any that had both a long TXD and low deviation. I never copied any of the long TXD packets (not while I was listening, anyway) so I...
scott, I took a listen to that flutter, it sounds surprisingly like the sound you get from a laptop, the electrical noise. i do some recording with my band in ...
Possible, since that is what Elmer, Don and I were using to record audio. However, that is never present in the bunker at any other time. Just so everyone is...
Build 54588 has been posted. You can grab it with the config program or here: http://n1vg.net/opentracker/firmware/ot2-54588.s19 I'm leaving for a weekend...
So, I'm sitting here with my d700 monitoring the aprs frequency here in Dallas. And I have an OT2m hooked up to my tm-271, and I'm monitoring the aprs packets...
If you really want to eliminate the variables, take the audio output of the D700 and feed it to the T2 (leaving the D700 TNC on, of course). Once you've got...
... Are the antenna gain figures the same? Are they at the same physical height? Are the feed line losses identical? Are the receiver sensitivities the same? ...
Knowing that people have not had good luck using USB serial ports, I have had some luck based on Scott's recommendation of configuring the T2-135 (with a...

... In 9600 baud mode... In a D700 to D700 system, you could call that "flat". The D700's in 1200 baud mode use preemphasized/deemphasized audio, which again...
Hi Group, I recently purchased the Tracker2 and have a couple questions about it. I will primarily be using it for standard APRS tracking in my vehicle (no...

Keith, Thanks for the response. See my replies below: 1. Sounds good. I will leave squelch open with SWDCD on. 2. It looks like I do not need to worry about...
