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.

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.

Image rejection: 50db 80db

It's currently under development but the first few chapters are complete

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:

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 ?

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.
