Expert 1.3K is DXpedition “game changer”

This is one of three Expert 1.3K-FA Amps brought on the VP8STI/VP8SGI DXpeditions.

Every once in a while a new piece of technology comes along that qualifies for what I would call a “game changer”. The new Expert 1.3K-FA Amplifier with tuner is certainly a “game changer”. This amplifier is small, light in weight and quite powerful at 1,300 watts with as little as ten watts of drive power. Yes, that is right, ten watts of drive will produce 1,300 watts or more of output. Just an amazing little amplifier. At about 18lbs it can easily be carried aboard an aircraft as a carry on item. It even comes with a padded carry case for that very purpose.

The Intrepid-DX Group acquired three of these amplifiers for the recent VP8STI/VP8SGI DXpedition. The amplifiers performed flawlessly and delivered a consistent 1,300-1,400 watts. Their internal switching power supplies performed very well even with regular voltage sags and generator shut downs. This is one robust and versatile amplifier.

On the back side, you can see that it can accept two inputs and can provide internal antenna switching for up to four antennas. We are very glad to have had these amplifiers. I now own one of them and will use it in my shack to replace a large/heavy tube amplifier.

What do you think?

    We had two of these at TX3X on Chesterfield and they were the workhorses for 80 & 160. Really good equipment and worth every penny.

    Thanks for the heads up on this Expert 1.3K amp. There is a DXer who asked me last week for a recommendation on a linear. The only ones I am personally familiar with are {a} ICOM PW-1 which has been a workhorse for me for the last ten years and {b} Ameritron ALS-1306.

    Both of these amps are pretty good. But with the ALS-1306 you need an external antenna switch / antenna tuner.

    For whatever reason I did not know about the Expert 1.3K amp about a year ago when I bought the Ameritron ALS-1306.

    I am going to mention this blog post to my DXing friend here in Oklahoma City.

    Years ago I had a boat-anchor Henry Classic 3KD with a 3CX1200D in the final. That was one heavy amp. I’m glad I don’t have it any more. Otherwise I’d be needing spinal reconstruction due to lifting that thing. As I remember that thing weighed in at 120 pounds!

    Whatcha gonna do with that old, decrepit, probably almost worthless tube amp? 😉

    Congrats on your recent tour de force. I look forward to seeing what you’ll be up to next.

      Hi Mike, I sold my Alpha 9500 just before I left for the VP8 trip. It was a great Amp but I started having doubts about Alpha’s future and I preferred to have an Amp that can travel with me. The Expert 1.3K is just perfect for all of those reasons. 73, Paul N6PSE

  4. I agree the Expert folks have a real winner. I took delivery of my 1.3 the first week of January 2016 and it has lived up to all the hype. Mine is a heavy weight at 21 pounds, but mine also has the internal automatic antenna tuner. All I can say is there is quite a waiting list, but worth the wait. Nice report Paul. …………….. Dick, W6KM

    On waiting list as you Big Guns took all with you!!

    I ordered one in August 2015, and its ETA was this month, March. Now ETA is June-July, but happily, I pinned down the year to 2016. Reports and comments like these are going to keep me drooling into the summer months (and beyond?).

    Thanks for your tantalizing comments and reports!

      Dan, these really are awesome amps and much in demand. We just ordered two more of them and the wait is a year.

      Best wishes, Paul N6PSE
