I like mine!

had no impact on SWR

some pictures of my 667v. Any help much appreciated.

they do the cw/11 meter mod

sp5it, thanks for that thread. It will give me a lot of meat to chew on.

copper electronics :(

antenna analyzer: SWR is flat on 27205 with a bit more on ch1 and 40 monitoring 667v with cross needle meter between amp and antenna 667v swr can go to 3:1 at full power. modulation brings SWR down to 1:1 like watching PEP swing. various other amps no SWR issue what could this be? (did a...

My experience is probably different from yours because the first Galaxy radio I ever bought was in 2020. I think they all were made in vietnam.

I can confirm the RM Italy LPF does filter out the 54Mhz harmonic.

yes thanks. My post above yours is the link to it.

CB BANDPASS Filter?

I got a report last week that mine sounded better and had more swing than anything else that I have been using. All subjective, but nonetheless... interesting. I have a large number of radios. No pride of ownership here though. Galaxy radios are mostly junk held together with more junk. :) I...

The way I understand it is unlike a lowpass filter, which in the case of a Drake 30Mhz for example, filters out anything above 30Mhz so it will suppress the 54 Mhz harmonic if there is one. You will see the SWR on your radio higher with the AMP on but the AMP to the antenna may be a perfect...

Fact or fiction

https://www.tinysa.org/wiki/ the filter is a quick and dirty way. This will be more informative. ...Maybe just getting my feet wet with Spectrum Analyzers. :)

for me, it's going to be for testing/reducing SWR between the radio and the amplifier. If it suppresses harmonics and spurs, it will point me to the problem. I already verified the first order harmonic, 54Mhz using a 30 Mhz low pass filter.

https://surgestop.com/filter-products/m-411cb.html I ordered one of these the other day. Just wondering if any one had experience with one and if it solved their problem. Model: M-411CB Frequncy Range: 26.9-27.4 MHz Impedance: 50...

It gets much worse. Now, technology has moved forward so much that acronyms are nested inside acronyms. So, one letter of an acronym stands for another acronym. It makes 5G it so easy :(

Those are secondary ground planes. They assist in the "lift-off" of people like me's wallets out of the hip pocket.
