Probably the reason the frequency was so interference free, is that it was on the international maritime distress frequency 4125 kHz.

Probably best to avoid that in the future, Mix Radio International.

  • Effective Jan 01, 2005 U.S. Coast Guard long range communications stations NMF, NMN, NMA, NMG, NMC, NMO, NOJ and NRV changed their single sideband voice radio guard to the following simplex frequencies: 4125, 6215, 8291, and 12290 kHz. These frequencies are intended for initial voice contact and distress alerts and working only.

There was a captive audience: the Coast Guard monitors that freq 24/7.

<sarcasm> To step in bigger doodoo, try 5000 kHz, 3330 kHz, or maybe 11175. </sarcasm> :)

do you think that could explain all the non english chatter on frequency after mix went off air ;-)

The RF Workbench / Re: New here, and my journey building a SW xmtr
« on: September 23, 2018, 0117 UTC »
cool you got it going .
there will be some who disagree with this.
i used a dipole as a inverted v just high enough to keep the ends off the ground about a foot .
and no earth ground .
1/2 watt carrier approx. was heard last night by ChrisSmolinski and it wasn't in his backyard by a long shot.
 no location will be provided so don't ask.

I think that The Relay Station runs 1/2 W into a "good" antenna during the daytime occasionally and people actually do hear it.

Indeed. I think sometimes even with less power  ;D

One S unit is a power ratio of 4. Signals can be heard at even very low transmitter power levels.
you should know Chris because you hear damn near everything.
including a MMM doing a half watt at least a few times. i know that for a fact.
i also know that you and most everyone else has been hearing higher power MMM's for years.

i think the MMM is just fine. making more power out isn't that hard either.
with or without a added rf section filter the output or you'll be throwing harmonics everywhere.
the output level of the MMM is affected by how well you tune the variable capacitor if you build it with one instead of a fixed value.
i could add add a bit more but if you build it you'll learn. it's part of the FUN.

so try it you'll more than likely like it . you can always build something else later.

sounds almost the same on lower sideband  :o
but  lacking a bit of audio quality  ;)
