First of the new amps is this 1.8mhz-30mhz 500w HF amp. It has 4 ea 2879 transistors and good for about 65-70w input. Output varies with the frequency and it gets a little more than 500W out on 80m and a little less on 10m. It is RF switched so not much use for anything other than voice. No externat PTT. It has quite good protection built in for overdrive, over heat and hi SWR. Originally it came with just a fan on the inside but where could the air go? Just a few slots in the back to exhaust…not enough air flow and no where to go. We asked the manufacturer to place a fan on top which he has done and now it stays a lot cooler. Quite a bit of heat sink for an amp of this type but without the added fan, once it gets hot it stays hot. Not much to say about it…pretty tough hi input power, low input SWR, solid state no tune amp that can work anywhere. Best we have found for the price so far. Order from www.Yeticomnz.com for your next portable outing.
Another AMp this time 2m. Tested to 330W FM. Nice and tidy. Lots of power on 2m for those that need to be heard. Nicely made.
From RM we have a 100w amp for UHF CB. Works up to 477mhz but output only 85-90w. Not bad for 5w input. Like all UHF amps a little expensive but it delivers the goods. Another keeper for the mobile or working the repeaters from far away.
