USB is awesome, no doubt. The problem with USB GPS receivers is that, unlike the NMEA, RS-232 "standard", USB device drivers are different for each and every model. That means that things like the TT3

You may want to consider a GlobalSat BR-355. I have used them on TT3 for many years. It is a SiRFStar (III or IV depending on how old it is) and supports a wide range of NMEA sentences and can be

I found one on eBay for $25.00 and just didn't feel comfortable purchasing it.? I will see what else is out there as I feel this deal is too good to be true.? Also if the TT3 is putting out more

Robert is quite right about the plethora of inexpensive GPS modules out there. If you plan to use one for your TT3, and it is a 2 or 3 Volt supply version, it may not have enough drive to work with a

Well, I for one, am not amoung those missing RS-232.Garmin and everyone else are following the computer industry which dropped RS232 and GPIB, EPP,? ECP, etc.? USB has so much more capability and

Matt, I dug up the spec sheet for the Garmin GPS 16 LSV ( https://static.garmin.com/pumac/GPS_16x_tech_specs.pdf ) and it looks compatible. You will need to do some connector surgery. I see these are

That choice of GPS seems a little strange.? The GPS 16 LVS is an OEM (made to be installed/connected in some device).? On eBay it asks for a vehicle make. Also it seems like a lot of cash to dish

It's been several about 10 years since I have used my TT3+.? I had to stop using it because the Garmin GPS was a handheld unit that gave up the ghost while geocaching one afternoon. With that said, I

I suspect that you have a problem with high SWR that is either causing your WxTrax to lock up due to high SWR, or, high SWR caused your unit's firmware to become corrupted. Try it with a dummy load

No, everything is the same. When powered up, it pings 2 maybe 3 times and that’s it. I’m guessing that the timing circuit is bad. This is tied to a Peet Bros Ultimate 100. When it pings there is

You are sure none of the radio settings have changed - specifically having to do with squelch? I assume you haven't made any changes to the WXTrax settings - other than ping rate? Robert Giuliano

I have a WX Trax that has worked for years. Now, it will key the radio when it is first powered up. But, regardless of how I set the ping rate – 2 minutes, 5 minutes, etc., it won’t key the radio

I have a newish (couple of months) TT4. Connected to a Motorola CDM1250 radio on 2M. When I put it in AMODE TEXT, it works for APRS on my PC (PinPoint) - it sends and receives APRS seemingly just

Keep the product alive if it's not a burden.? That's my vote. ;B

I just thought I would give you an update on a few projects.? One new product is our MTT4B-Mini. This is a TT4-based transceiver with nominally two watts of output power Max. It measures about 1 X 2

Thanks to Dave, Greg, and Rob.? All your help did help me get the TT4 working!? Suspecting the Ft-8900r was the problem I again swapped out the ft-8900 with a different radio, this time, the ft-2980

Yeah, I looked at some. One module, simply called aprs, had oodles of errors trying to add it with pip. Another called aprslib seemed decent, though I didn't need all the parsing and other stuff. I

FYI, there are a few APRS python library that can help with the interface. Robert Giuliano KB8RCO

Well, I peeked at direwolf, but it is a giant program, and I really just wanted a few python lines to do the posts. After a bit of poking around and figuring it out, I was able to get it posting with

Then dig deeper into Direwolf with no "radio" attached.There are hooks to Python, Perl, and CLI (Pi command line interface) for getting the data in, and the Direwolf side will handle the formatting
