Brian needs more power... any suggestions ?
OK
Brian would like more power
He's got his new antenna fitted a 1000W Dominator At the moment driven at 150W from a Chinese board using a MRF9180 with good results
I am thinking of a max of 600W (which should give me a theoretical ERP of 1200W) 6db increase
But I would like to have it variable power output (say 30W > 600W) driving from a 1W exciter
I have my own idea but... any suggestions

Being based in Spain I'd try to find some second hand equipment. I've seen some amps and tx's in the buy/sell app "wallapop"

Re: Brian needs more power... any suggestions ?
I know someone who has used one of his amps a few years ago but with the more powerful 1,400w device.
....But was only but was running it around 750-1000w maximum because he was a bit concerned about the size of his heat-sink and keeping it cool, but he never had any problems with it and as far as I know he's still got it in perfect working order.

Re: Brian needs more power... any suggestions ?
I could not find a 600W kit with a BLF174XR only a 100W & a 1000W boards
Also a reason I don't like the Dutchrfshop is even if I change to English on the page I still get hjsyfkdsj stejrhfndgqs language

It's only Arguineguin that gives me a problem, all the areas are covered fine.

Why not just go for the maximum power your aerial can take and just go for the full 1,000watts?BriansBrain wrote: ↑Thu Jun 18, 2020 5:50 pmLike I said above

....The price difference of the more powerful amps compared to the 600w version is so minimal, you might as well just maximise!
