hey W5LZ i thought you might like this picture.i originally used the 1005/frequency=length and after talking to a ham buddy and reading around my conclusion was that 468/frequency*2=length seemed much easier.this loop was meant for the top of 27 mhz and i started at about 36.5 feet with 9 ft...

no no no if your looking for broadband and your considering a a99 forget about it and get a imax 2000 i had both and i will never ever own another a99!if i want to get out like a a99 i will build a vertical dipole and hang it from a tree however the imax 2000 is much better and if you want to...

w5lz as usual you hit the nail on the head alluminum is alluminum copper is copper a watt is a watt if it looks the same it probably is.73s w5lz 1342 ny just got down.

thats it pumphouse no pep on my bench and if anyone would like to do a shootout with me -there pep watts verse my average watts they will be disapointed but i am willing!

oh sorry about that i meant the wolf .64.which one came out on top i am hoping the wolf.

solder a jumper(piece of wire from one side of the diode to the other side of diode)this increases the voltage to the collectors of the final transistor and possibly the driver transistor i believe.

yes the transistor is the 2sc1969 that was what i was talking about look around some more and read other similar mods for that radio you may even find pictures that will clear some things up for you.there may be different variations of the same modification to that radio.look around and let me...

there are several mods for that radio floating around i have done the transistor swap on some cobra 29s with the 25 volt cap and 100k resistor i am not sure if thats the one your refering to but it did yield a low dead carrier 1-2 watts with forward swing up to 7-8 watts average power with great...

cool pics marconi which one of those antennas perform better.

well there is a wya to test these and i dont remember how hopefully someone will chime in here but if you see the part # you can either get 1 on ebay or order 1 from rf parts if they still carry them but they may have a minimum 25$ order not sure.this is a common problem with many of these small...

great post city boy that is what i figured on the output but if you say that to most people out here they dont like it the facts are clear for me this is not a 100-140 watt transistor!the only transistor i know of around that # would be the 2sc2879 and that mosfet is no 2sc2879 but anyway i was...

sounds like the 10 pin audio ic

good call i have only seen about three listings for average power on this rfx and they were from 30 to the highest of 60 watts.45 real watts on a cobra 25 is great:thumbup:

great post flush i have argued with techs about this and you just proved my point!you would think of all people that a tech would allready know this but i guess if your buisness is selling radios to truckers and the pep major needle movement is a good sales pitch. thank you.

after my imax snapped i put this homemade dipole up vertical not quite as high as you can see but it matched to 1.1 with no baluns or tuners just wire to coax to meter.had several skip contacts and local talk to 70+ miles.hooked on top with bamboo at 90 degrees plant hook to hang and duck tape...

thanks for the fast response guys i originally cut this for 27.475 and have not figured a mounting setup i put 4 bricks up there for now to keep its shape even with the match above 3 i can receive almost as good as my v 5/8 40 ft to base or 30 ft above loop and did make 3 contacts that were very...

hey homer i built one of these a couple days ago length was 36.5 feet with 9.1 ft of 75 ohm i laid it on my addition(almost flat)in a square but have not got the match below 3 yet any tips would be great.oh and where is your 75 ohm at compared to your antenna under,away,vertical,inside or...

i think you missed my point.my collins 30l-1 is also rated in pep at 1 kw however it does over that with more drive in AVERAGE POWER!so if your ameritron isnt hitting its mark on average power feel free to give them a buzz.:thumbup:by the way sounds like a nice setup:thumbup1:

not to sure on actual numbers but i know this out of the three meters that i have two of these read pep at about a 2 to 3 times higher than average power.as you stated before a watt is a watt!why some think by switching a pep switch or a pep meter is going to change output 2 to 3 times higher i...

hey switch there was a topic about texas star not to long ago and i think that all companies are getting on the pep bandwagon.back in the day an amplifier power claim seemed pretty dead on 250 rating on an amp could get 250 in pep or average ssb output real power!sporting some 2290s-or 2879s i...
