  1. Looking forward to hearing reports on how the amplifier works for you.
    We have a Yaesu FT-817 on the boat and we are thinking of stepping out of the QRP world.

    1. Hi Scott: I ran the amplifier off of the Bioenno 15ah lifepo4 yesterday for the ARRL Sweepstakes. It worked great! I want to use it some more times before a final verdict. I’ll bring it up to the Hill next time. Mindy

    1. Hi Bruce!
      That is the MFJ-847 digital swr/wattmeter. The amp does put out the expected 100W with 5W driving from the internal battery of the 705. If I am reading your mind, yes it would work with the 817. It only weighs a bit over 3 pounds and is cute as a button. I’ll bring it by on Tuesday.

  3. Hello Mindy!
    What model number RM amp did you end up purchasing and from what dealer?
    My 705 needs a little HF boost also.
    thanks

    1. Hi Dave:

      It is the RM Italy MLA100V. The “V” is for the model with the fan. Given that this is my first amplifier, I actually had no idea if I needed the fan or not (still not sure, though it is fairly quiet and doesn’t get in the way).

      I got it from DX Engineering, and spoiled myself by overnighting it. Absolutely no problems with them. The following is the link.

      The only extra part needed is this cable for t/r switching.

      Let me know if you get it!
