Board # A2347 - 4 - 0 ?
(Only number I saw)
Does anyone have the clarifier mod for this as It is a different board design that side mic models.
How about the receive mod diodes?
Any help would be apreciated! I think these are the worst 148's cobra put out, but my freind wants the mods, so I am trying to help! Thanks in advance!

Clarifier modification
1) Lift anode of D-30 and connect a 5.6 uH choke in series.
2) Cut D-32.
3) Cut both traces on the PCB going to the clarifier .
4) Solder one wire to PCB ground.
5) Solder a wire from the other cut trace to an 8 VDC source
(note: 8 volts can be found on the cathode of D-50)
6)This should give you 5 kc of slide.If more slide is wanted then change D-30 to a super slide diode.
VERIFY THIS BEFORE YOU DO IT. I HAVE NEVER DONE THIS ONE.
