About

I am originally from Mercedes, TX and have been living in Brownsville, TX since 1984.

I recieved my Amateur Extra license as KG5EAO in 2014 and have been enjoying making voice and digital contacts on HF. I am using an ICOM 7300 and an ICOM 7100 with a MFJ-939 autotuner. I use a 53′ Ultimax DXtreme end-fed running horizontally along the length of my house about 20 feet off the ground and a homebrew 1/4 wave vertical for 20m and 40m. I am using Ham Radio Deluxe for rig control and an SDRplay with HDSDR as a sort of panadapter.

I have a portable, solar powered station based on a Yaesu FT-817ND with an LDG Z817 autotuner for QRP operation. I also use a Yaesu FT-450D for portable use. For portable antennas I use a homebrew Buddistick, Buddipole, Magnetic loop or an EFHW vertical antennas.

I am also interested in various antenna designs and analysis using EZNEC. I have tested a 2m Moxon antenna and a 4 element 2m Yagi for use in valley-wide simplex with encouraging results. I am testing a variety of HF antennas in mainly vertical configurations. These include resonant 1/4 wave vertical for both 40m and 20m, non-resonant verticals 31 feet long and EFHW verticals. Many of these are testing using WSPR.

I am active on JT-65 and SSB and am in the process of learning CW.

For 2m and 70cm I use two Baofeng HT’s for mobile/portable and the IC-7100 for a 2m/70cm base station. My base station is currently using a discone antenna. I typically monitor the local STARS 147.04 repeater and 146.52 simplex here in my area. I also monitor local DMR repeater.

    I Have just recently purchased a APRS Track X1C 2, without instructions, so found your words tremendously useful . So I thank you for that.
    I do however have one Problem in that I cannot get the unit to accept my Call sign.
    I can change other parameters for example “AT+SSID=9” and it will work.
    When I try “AT+CALL=GM7FGH” it does not and returns “CMD ERR ! Try Enter”
    Can you tell me the exact method you use to insert or change your callsign.
    Thanks again.

      AT+CALL=GM7FGH should do it. The command error looks like it is a serial issue. You may check your terminal app settings are 8,N,1. I had some issues until I used the termite program.
