I am having my awm-30 true peak reading meter Calibrated
by W8JI Tom. He is still the best in the Consultant Engineering
Business.. Too bad we ran him off. He dont have time for
forums or Arguing. He is the best Rf amplifier designer in the
Country,

Very True
Easy-to-Drive Linear Amplifiers
Some hobbyists and manufacturers tout "very low drive" as an advantage, claiming it offers "cleaner signals". Nothing is further from the truth.
Exciters almost always provide the best IM performance when operated at a time-averaged peak power a...
Yes it is Flawed . I specifically ask Mike why he did not check the kl7405v I sent him with the Pearce simpson radio ..
I sent the kl7405v that has regulated ab bias along with the pearce simpson radio so he could match the radio up to the amp.
Which he did as I ask. The kl 7405v has 2...
I am with Tom w8ji below why would a low pass filter be needed ?

A good quality lowpass filter would be a useful thing to fit just before your inline power meter assuming you are using a typical Ham power meter.
By Ham power meter I mean anything from...
Efficiency
It is naturally important to ensure that the proportion of the power dissipated in the loss resistance is as low as possible, leaving the highest proportion to be dissipated in the radiation resistance as a radiated signal. The proportion of the power dissipated in the radiation...
The Cobra 29 ltd has the best recieve , actually better than the exports.
I have 4 made in the phillipines , of course there AM only, but Rock solid.
Typical values for each radio:
Adjacent channel rejection : Export 50db 29LTD 60db
Image rejection: 50db 80db
Selectivity...
Can now read a free text book on line.

It's currently under development but the first few chapters are complete
and looks like a pretty good reference.
Lol... you make a good point. It did not have that sound on the ts-50 on AM its low level modulation.
I can relate to what you are saying , most of the guys on 80 meters have the same problem too much compression and the highs is like fingernails on a chalkboard:eek::eek:
I think it...

My question is will the cobra 29 sound better with the heil hc-4 mic opossed to the stock cobra mic , by using the adapter box in the link above ?
Forget the mixing/ equalizing.
Yes. Not worth the effort.
http://www.dk3hv.com/SSB-Audio/Heil/heil.html Listen to the 2 elements.

This would work.. Do you think it would sound ok without any equilazation or mixing ?
Thanks , Bob emailed me back, the unit will have equilization also. He said probably by the end of the year.
I like the hc-4 he made when i had it on the ts-50 kenwood.
Is there a way to run the hc-4 on the cobra 29 ?
My understanding is it will not work.
RPC, this is a email i sent heil about his mics on the cb. His end quote i hope will come to pass so we could use them on the cb.
Hi Tony
DOn’t have any thoughts on this. Hand microphones are always pretty terrible. The other situation is the the CB transmitters do not have good audio to...
I had a p 300 years ago a cb tech either changed the voltage regulator out or put a bigger audio transformer in it.
The radio came alive it had killer audio.
Sorry i cant remember. Good Luck
Does anyone Know how to contact GOHZU ?
I know this thread has been dead a while.
He seemed to up to snuff on recieve alignments.
I would like to know if Sinad is the best for aligning the cb for recieve.
As far as s/n ratio.
I know Sinad is used for FM but have been told not for AM...
Thanks.
I like the old coffin style cobra stock mics
The audio clip is of a stock 29 with this mic. It may have a hillbilly sound ...after all i am from Ga. Lol :)
