    I need to put an swr meter on mine and get a new antenna that I can keep grounded better.

    Yeah, tuning the antenna would really help the SWR come down and get better distances out of it.

    I tuned it when I installed it but I think my mount has rusted a bit and I'm not getting a good ground anymore. I want to switch to an antenna with a separate ground wire rather than relying on th mount for grounding.

    I'm planning on a remote faceplate radio mounted below the mirror. It will let me have the radio in an easily visible spot but be able to detach and toss in the glove box or center console so it's not so obvious I have an expensive radio all the time.

    I opened up one of the Anchorage repeaters with my stock radio, just ran it on high Tx power! It wouldn't reach it on low power.

    So I went to the KL7AA club meeting. Lots of old guys lol.

    Few things I thought you might like to know Mike @ffirg (and maybe others)
    -they are going to try and lease the old FCC building on Raspberry Road right as you enter Kincaid Park, this would be the new clubhouse
    -New website in the works since current site is rather dated

    Had to delay until the April test date. Studying for my real job took up all my free time leading up to this weekend's test.

    I tested the stock antenna that came off of my BaoFeng UV-82HP I just bought a couple weeks ago, stock antenna is pretty bad for APRS freq. Much better for the UHF spectrum. I will try and run APRS off of my HT until I can get a decent mobile unit either this year or next, but I'm not expecting that far of a Tx or Rx distance with it.

    I will post screenshots of my results from one of our network analyzers at school Monday. By using the network analyzer you can see how bad the impedance mismatch is between the 50 ohm ideal and the actual impedance of the antenna at a given or sweep of frequencies. This mismatch is what causes standing waves due to reflections that happen in the antenna and cables, leading to the more common SWR--the standing wave ratio. Anything above a perfect 1:1 means you are heating your cable/antenna and wasting energy when transmitting, and receive quality goes down too.

    TLDL the stock antenna sucks for VHF and is better for UHF

    Yeah, I'm so out of the loop on this thing haha. I really only see myself using simplex comms anyway. But that's also because I have no idea what I'm doing with repeaters and whatnot.

    Yeah I want to figure all that advanced stuff, but currently haven't even used my radio to talk to anyone lol.

    Okay as promised here is the data from our network analyzer.
    These are showing on a Smith Chart. Closer to the center is the best and represents a SWR of 1:1, halfway out of the center to the edge is a SWR of 3. The lines show a sweep of frequencies, the full VHF and UHF frequencies shown on the bottom of the antenna.

    VHF Spectrum, the marker shows 144.390 MHz, or the APRS freq.
    Swept from 136 MHz to 174 MHz

    UHF Spectrum, swept from 400MHz to 520 MHz

    Tried running APRS on my baofeng on Saturday, forgot to turn VOX on. :anonymous:

    Took the test Saturday and have my call sign already. The club and FCC work quickly.

    Bought and installed a Kenwood 710G and it's been awesome. APRS tracking and messaging works great. Voice range is good and transmission quality is reported to be very good. I'm using a small magnetic mount antenna on the roof right now and will eventually upgrade to a 40" mounted on a hood bracket mount once I figure out what antenna to buy.
