Been experimenting with a MX614 demod chip. Have found that it will decode a RF signal level that is about 5 dB lower than the best I could get with the 2211....
I noticed that Scott (N1VG) mentioned that the T2 uses a 100k resistor in lieu of the OpenTracker's 220k to get a higher level of audio output. As I'm...

Has anyone noticed with the lastest OT2 firmware a "Database Error" comming up on Garmin units when in standard two-way NMEA mode? I have a 176c that up until...
Not sure what I'm doing wrong. I reflashed the T2 with latest firmware, blanked the config in the process. I configured config 1 with a fixed position, then...
Hi all, got my ot2s in the post saturday afternoon. A couple of hours for assembly and voila! It is a very well arranged kit, for it worked as soon as I...
Hi Gang-- I'm new to the beta testers. I'm trying to set up a basic WIDE1-1 fill- in digi using the T2-135. I'm a bit confused on the parms, can someone ...
I've added a few items to my store that are particularly useful for the T2-135. There's a F-M gender changer, which doesn't really change the gender, but if...
In case I didn't mention this already, I've got some shorter (3/16") 4-40 screws available in case anyone's having trouble with the case screws shorting...
Sorry for the long delay - things have been a little hectic. This version includes changes for the Proto C boards. Also added the MAXRANGE command, to limit...
So far so good. Scott, You need to add the socket for U7 on the parts list. Will you be brining any enclosures to DCC? Can't wait for the 1-wire stuff to...
If the serial port are layouted as a RS232 on DB9 (EIA/TIA 574) shouldn't pin 5 be ground? I find ground on pin 1 and RX and TX on pin 3 and 4 /Conny...
Here are my notes that I sent in a private e-mail to Scott. The second part is my suggestions for making the kit easier to assemble and use. Perhaps other ...
Scott, I have been looking at how OT2 digipeats. It looks like the only valid ALIAS values are WIDE1 and WIDE. WIDE1 behaves where any WIDE1-N will be ...
Scott, The OT2 rev C parts list shows a Q1, Q2, and Q3, but I only have 1 2N7000. It looks like on the schematic there is only a Q2. Is that correct? 73, ...
As an experiment, I pulled the '2211 completely on a T2, and routed the analog input to an ADC pin (AC coupled and biased to 2.5 volts). I implemented a...

I built and tested 4 more T2 boards for the Alinco DR-135T. 100% success rate so far. I'm offering these to beta testers for $45 each, assembled and shipped....
Scott, is there a reason that the FET isn't turned on by default when the power control box isn't checked? I have my wife's tracker setup for 2 modes... mode...
Who's coming to DCC in Tucson this year? They had a couple of speaking slots open, so I volunteered to give a 45 minute talk about the T2, and show off some...
The Proto C and T2-135 boards came in today, a couple days earlier than I was expecting. I thought I had some ST202's on hand, but I can't find any, so I...
My first attempt at a distance calculation (using a floating point implementation of the haversine formula) required 5 trigonometric function calls, two square...
Scott, The two screws that tighten the two parts of the enclosure are too long and touch two pads on the PC board when tightened. I am going to fix mine by ...
I've been testing the xmodem upload some more, and I've found that it works fine on my Linux box using 'sx' from the command line. When 'sx' is launched from...
