what sort off price do they sell for in the usa guys ??
 

Good post here

New Palomar HD250FET and HD450FET


from what I've read on the net..they ( FET250HD and the FET450HD )
put out about 4 1/2--5 watts for every watt put in.




Spec's on the amp here ( this is also where I bought mine )

------------in MY case----------

I have never checked mine with a meter ( don't have one )..but using real world LONG distance radio checks..it brings me up and average of 2 S units on SSB and AM.

NOTE: I'm NOT able to drive the Palomar FET450HD to it's full output..( I'm only driving it with 63-66 watts.)

It works great on SSB..AM and FM

Also in MY case..it really likes a long jumper between radio and amp. ( I'm using 18' )

the shorter jumpers ( 2'..3'..6'..8'..12' ) caused the amp to chatter and sometimes not want to un-key.



A few pic's of my " Palomar FET450HD "

I added a fan to keep it cool.....Masscool 140mm 2 Ball Bearing Silent Case Fan

And a very small toggle switch for the fan....Radio Shack #275-0645

I cut off the fan's computer wiring harness and added the switch and new wiring....then covered the switch and wiring with hot glue to keep everything in place.

Then added some 1 inch rubber feet from Lowes....Grippers #0054238

Ive got one, its output is a bit dirty.....but what do you expect for a "cb linear" I was getting more towards 500 watts out of mine and it stayed cool with a fan similar to the one pictured.

I wouldnt buy one again, but it is a decent toy. It has made the difference on contacts in jamaica, brazil, australia and into canada when lots of 100w import radios were on air.

keep in mind this is a cb grade product and wont give you the same perfomance as nice amateur gear.
 
I ordered one from DNJ before I inquired about it here in this thread. I noticed my account activity kept saying processing.

I emailed Frank... He replied that they have to make me a "brand new" one and ship it out this Saturday. :confused:

Anyways, as I always say... It's only money. I'll check it out and if I don't like it, well... off it will go.
