Hi guys,
Searched for other threads on this and found this one.
I just got one myself. This radio should finally fit my needs and be done with it in the vehicle.
The 4300's are great radios but have an inherent problem from new. Yes they WILL work with just the 11 meter conversion performed, but tend to be squealy at some settings like full power, full mic gain and sometimes any talkback usage.
I got burned....it's so shameful I know
but I will man up and admit that I paid Coppers $30 for their expand & tune service.
Sure the radio "works" as arrived but was not acting right and was easy to make it squeal.
So I ring up my trusted - but 40 mile away - tech at a radio shop, and he tells me yeah yeah blah blah the 4300 series is great but the talkback circuit is defective or not optimally matched or something to work right with the radio when the rest of the radio is properly realigned, peaked and tuned to deliver the 90 watts out (from original 70) that they all will do...and to be loud with a big swing of course.
So I tote it over to him, he shows me the sloppy work coppers did, repaired...he called it completely reworked.... the talkback circuit, and correctly peak & tuned.
So there we go. This talkback circuit mod. is apparently needed on the 4300 and perhaps some other of the HP models too. Fix that....and you got ya a 90watt screamer in the mobile! gonna kick some tires and light some fires
:
Also did not immediately find any peak & tune info on the net either, and certainly nothing about the talkback circuit issue. These are awesome radios and it looks like the techies are keeping quiet about this one
We'll have to see about that.....
