I would agree a 1/2 wave antenna would be the best bet. Interesting mount hadn't seen that one before.

Yeah I agree, but thankfully they pretty much keep to themselves on a couple of frequencies though they do like to interfere with DXpeditions and special event stations and such.

As a licensed ham we are allowed to run 1500 watts and can operate in the microwave bands. Point either one of those at someone or have someone touch them while you transmit and it can cause some bodily harm. At least with a test and a license to show you passed the test it shows that you have...

Followed a guy going from SE TX to AK using his APRS. Some spots of no coverage but overall not too bad, at least in the lower 48.

For vehicle to vehicle I would agree that GMRS is probably the way to go. If you need a little more range mobile GMRS is good..... however if you compare the cost of the radio and the license you can get into ham radio for about the same or cheaper, depending on what radio you go with. GMRS is...

Fox hunting is a game within the ham radio world where you locate a transmitter based on it's radio signal. Now it's not exactly GPS/APRS map tracking but perhaps another option. http://www.com-spec.com/thecatlocator/index.htm Unfortunately they only put out 1 milliwatt but the battery last 30...

I believe the PTT is on the front since the SOS button is on the side.

They operate on FRS at 2 watts and they can talk to other handheld 2 way FRS/GMRS radios. But yes similar to gotenna as well.

Dave I am not sure the FCC agrees. "Rather, these devices may only be imported, advertised, sold, or used only if the FCC first has approved them under its equipment authorization process (or unless the devices operate exclusively on frequencies reserved for amateur licensees or they are...

Congrats Colin. The 2980 is likely a good radio, have heard the 2900 was a tank. Not sure what they changed besides adding 5 watts. The Yaesu 3100 is a good radio and the front firing speaker may save you from having to run an external speaker depending on where you mount it. I have the 3100...

Congrats Cody and Jentry.

Dual band (1/2 wave on 2m) on the front fender for voice, 5/8 wave on right rear corner for APRS, and 102" whip with adjustable loading coil (really more like 110"+) on left rear for HF. I am switching back to my older XJ and the dual band will move back to the roof as well and may be replaced...

In line of sight communication height is always king. Fender mount will work, just not as well as it could up top. I switched vehicles and went from a roof mounted antenna to a fender mount and definitely noticed a difference in receive and transmit. Not only due to height but also likely due to...

There is more than enough metal to act as a ground plane for UHF, signal may be a little wonky if you mounted it to the cross brace as the main metal under the antenna is off to each side rather than in all directions but it should work.

I use a Mobilnkd tnc that bluetooths to my tablet. Two less wires that I have to have running around the cab of the vehicle. As long as you are on 145.8258 Mhz and have your path set to ARISS the SMS-APRS procedure is the same as it would be for terrestrial use. I hit ISS/Satellite digipeaters...

You're right. For some reason I was thinking the switch would be between the radio and 2 separate relays. Don't know why...

I thought about that, but I don't like having all the power running through the switch to the radio.

Wire up a double pole double throw switch, where one direction would allow a switched power source to trigger a relay, and the other direction would connect an always on power source to trigger a different relay. You could use an on-on switch so it's either one or the other or an on-off-on...

I use APRSdroid on a tablet with a mobilinkd tnc connected to a Yaesu FTM-3100 mobile. Works great. Tracking my Jeep, sending messages to other APRS users, SMS text messages or emails to the wife, through the ISS/Satellite all good stuff.

I know this thread strayed off topic a bit but I think it has been a good civil discussion.
