My new radios

-127 dbm with nb on and auto squelch on lowest setting.
-130 dbm with auto squelch off and nb on
-137 dbm with auto squelch off and nb off
No schottky diodes
No 2SC2999
Pretty much Factory parts and a tune on the receiver


Should be seeing them in a couple weeks

 

Watch this video and I think you'll get the idea.

 

Dynamic range is something that Mark doesn't show on his videos but it's something I'm going to have measured at a Laboratory. That low noise floor is completely useless if you compromise the top end of the range of the AGC circuit. Lots of guys try to do modifications for better receive and quite often it comes at the expense of front end of overload in close proximity to strong signals such as a truck stop where somebody is running lots of power in the parking lot. Those numbers I threw up there are simply the generator output levels necessary to create an audible tone but the audible tone was not measured. So it's not exactly scientific. But I'll have a Lab look at it and give us some concrete numbers along with the dynamic range numbers.

 

Was planning to send it to Sherwood Engineering, but if you want to do the test you are more than welcome.
Figured an unbiased 3rd party would be the way to go

 

Yes it is. It won't light up the inside of my vehicle like the Magnum. Nice mellow display that is easy to read at night without blinding me.
