Amateur (Ham) Radio BS and Callsign Thread!

So I have a techie question.

On the Yaesu FT-70DR, can a tnc port be added, since the unit uses the signal to give info on its screen?

When I was a kid, we used to do stuff like this on gear to make it what we wanted.

 

Whether it's a bad idea or not kind of depends on how you use the radio. Motorola makes DIN mounts for many of their mobile radios because it's a standard that is easy to build radio cabinet around and not all up fitting uses face separation kits. So the key to mounting is knowing you need air flow, especially if you're one who likes to hold that PTT down a lot... It's definitely important to consider it.

 

I don't have DMR...

 

I am still unsure what DMR is....

 

If I'm not mistaken the FT-70 has the typical Yaesu 4 conductor (TRRS) speaker/earphone/mic plug (similar to a FT-60R, VX-6R, etc). If so it should straightforward to interface a TNC to it.

 

Gonna have to test my googlefu and brain power here........

 

You'd use the radio like a plain analog radio (not C4FM/Fusion). This is what a Mobilinkd TNC3 looks like connected to a VX-7R through the speaker/mic plug. I don't think the FT-70 has any built-in TNC or APRS, right?

 

DMR means Digital Mobile Radio. It's a digital modulation mode, meaning your voice is digitized (the term is encoded) and over the air the radios talk using a digital protocol, almost like simple computers instead of radios.

This is different than analog modes such as FM, meaning frequency modulation. That's what most VHF radios use. In that system your voice is analog. There's still magic that has to happen to transmit and receive your voice but it's all done without any digital technically.

The reason people use DMR (or similarly D-STAR, Fusion, etc) is by digitizing your voice the information can fit in less RF space (called spectrum or bandwidth) and benefit from digital error correction. In some cases you get more usable range since a computer can pick out a one or zero from the background noise better than most human's ears can understand voice with static.

For hams digital radio is something to tinker with, analog FM serves us fine normally. Public service especially like digital because it's easier to encrypt.

 

Quick search on the tube about you revealed......

Seems I am not the 9nly one frustrated by the lack of a tnc port......

 

Sorry, was in the middle of getting appliances delivered and didn't realize the model got changed

I was actually referring to the Yaesu FTM-400XDR, and the tnc port. The solution I found uses the Bluetooth function on oyur phone/tablet...…...which means no Pandora on my Head unit.
I had a conversation with my son to rip out the Taco head unit and replace it with a tablet so everything is one place...………………………...and maybe I am just too deep into he weeds. I did a member posted he sues a Baofeng for APRS and let's his mobile unit utilitze the A and B receive...……………………...

would need a way to mount the baofend since I dislike things floating in my cab,,,,,,,,,,,,,,,and wires running everywhere...…………...

 

Yeah, most police/fire/EMS radios are crammed into cabinets with less air flow than the dash. I would be worried if using it for heavy transmitting like packet or APRS (not setup properly), but for normal trail talk, or net traffic during the morning commute, it should be fine.

 

It's really just showing yaesu made a mobile digital rig and desired to try for one last market by adding aprs

 

Hide the baofeng in the center console or dash. Run you external antenna and power cables there. When you want to use it, simply turn it on... just don't forget to turn it off when your done.

 

I was actually thinking mounting it to the back of the console,,,,,,,,,,,

but the glove box seems better...……………….out of sight.

 

We're both talking about hams, right? Lol

 

I'm really disappointed there is no way to extract location data from YSF using the FTM-400 & FTM-100. Yaesu should have dumped the location data from YSF to a serial port in NMEA0183. Then a wide variety of solutions would be available to map the positions.

All the APRS fans here and nobody has one of these yet??

 

It looks to check many boxes for sure but the face doesn't separate from the body so vehicle mounting isn't as simple.

I'm also not sure how the APRS works since the radio has no serial or data port that I can see. So I wonder the extent to which TNC can be accessed through Bluetooth and interfacing the radio to an external TNC would be a kludge using the speaker and mic connectors. I think APRS/DPRS is probably limited to position beacons.

The ability to use GPS to roam on DMR is cool, that's something that doesn't get much attention in ham but is used in the commercial world. That lets you program repeaters that get used based on location.

 

Mine is ordered...but dont have my license yet.

 

I can also here be talking to Max using DMR and I can be on Fusion or DMR. Here the repeater is all tied together with Dstar, DMR, Fusion and analog. True system fusion.
