    Homebrew 2 meter Vector 4000 in progress. Put it up 21' and QSO'd local for first check on it. Simplex FM 146.520 Mhz contact 16 miles apart got good reports on 5 watts and 100 watts out. S4 on 5w, s9+ on 100w. Receive was good, too. S3 on my IC-746 other station transmitting at 5w, S9 other station transmitting 100w. SSB was clean and strong.
    I have some refinement of the components but well pleased so far.

    Had a few minutes to wrangle with this antenna before dark today. Improved the feedpoint to make it more stable. Experimented a little with another gamma match.
    At the moment SWR is:
    1 6:1 -----144 Mhz,
    1.5:1 ----- 145 Mhz,
    1.4:1 ----- 146 Mhz,
    1.3:1 ----- 146.52 Mhz,
    1.3:1 ----- 147 Mhz,
    1.3:1 ----- 148 Mhz.
