    If you send a message to each other, it will automatically route through APRS-is to the other user. It works as long as both sides have an igate that is capable of gating IS->RF. Many gates are, but not all.

    The message is routed to the gate, that heard you last.

    The network is not sufficiently robust to send a message coast to coast via RF only. For long distance messages google "the golden packet"

    Is there a way of finding info on repeaters with igates and their limitations?

    Yep just realized it was a silly question. If I can look it up on there it clearly has to be tied to the inet and the person using rf has to be hitting a node with APRS-if igate

    Technically an igate could be connected to a private IP network, and a private APRS-IS. Rather then the public internet. That would be unusual.

    I don't know an easy method to tell whether an igate is gating both ways. (Other then testing it) They all gate RF->IS. I've not heard of one that does not gate RF->IS. However, not all of them gate IS->RF. Some are made with RTL-SDR, so they have no transmit capability. So they're certainly not gating anything to RF. Even if they have TX capability, many will refuse to gate positions from IS->RF. Many of those will still gate messages (IS->RF) if that gate has heard that particular station recently. Position reports or otherwise.

    It's not a silly question. I was just reviewing APRS.fi data to see if I could ascertain which gates go both ways, and which gate RF-IS only.

    Of course, you can always attempt to ask the owner.

    Congratulations on getting your ticket. The Baofeng isn't a bad little radio. If you haven't done so, replace the rubber ducky with a 1/4 wave and that thing will perform very nicely.

    Congratulations! I too recently passed my test and found the learning curve for me remains very steep. I started out with the baofeng but yesterday I finished installing my mobile rig (Yaesu FTM-400 XDR) into the Tacoma. I'm using the DMM mount but waiting on a part for the ram mount to finish it out the head unit. Amazon says today so I hope to get a pick up later.

    I couldn't pass up a Retevis RT3S when they were on sale for $65 a few weeks ago. With a firmware swap, it will hold 120,000 contacts. However I had one hell of a time loading a CSV contact file. Turns out, you must have a copy of MS Excel on the PC you're writing contacts from. I found this out through trial and error, figured I'd share in case there are others like me that use non MS CSV editing software.....

    Possibly a defective antenna? No idea on testing with a multimeter but I'd guess no continuity between the center and threads.

    Get an SMA-f to BNC adapter like this:

    https://www.amazon.com/DHT-LLC-AD075-Convert-Adapter/dp/B00CVQK466

    This will expand your antenna choices immensely. Personally I think either Diamond or Comet antennas are the best options.

    Hmmm...a V71a is only 1/10th of an inch taller than my FT7900 face. May just fit...

    Also, props to DX Engineering for being the only people to list radio faceplate dimensions anywhere.

    I've been looking to do something similar and had a few questions.

    How does the prinsu work as a ground plane?

    How well does that antenna hold up to brush and branches?

    What brand antenna?
