Is there a device I can add to the end of a 16.9 V, 150 amp supply That will allow me to turn it down to 15.0 volts and keep the ability to supply 150 amps?

This will improve the RF and peak output on DX-929 thru Dx-979. The ones that are used in these radios are only rated at 300mw. Q-52. Replace with a 2sc1973. The same one that is used in Cobra 142, 148, and 2000. Rated at 750mw, 1 watt typical. Replace R-253 with 18ohm If you are running a...

Does anyone know if there is an upgrade transistor for the RCI Ranger 2990 power supply. It uses two 2n6328's.

Gentleman, I believe I have found the cause and the Cure for the Galaxy radio drift. I will use the clarifier on the ranger 2950 versus the Galaxy dx2547 for instruction purposes. The Galaxy's all use a zener diode in its clarifier section that is an SVC 251. It has a rollback voltage of minimum...

I bought a DX2547 to verify that my channel kit will work in it. I checked the voltage to the power supply in the radio. As per other radios I have had that contained a switching power supply, the max voltage available is 13.6. I changed out the resistor that is nearest the VR control. It tested...

But it's shone on the schematics. What is it. Antenna warning light adjust? Or something to do with the clarifier?

Survey Do you believe a plug n play upper and lower channel kit with 10 kc step for Galaxy dx929 thru dx979 for $39.95, free shipping interest folks with Galaxy's?

What radio shares the same board as the Midland 79-290 cb radio. I have the service manual that I got from Sonoma. Unfortunately, the schematics are not really usable. Looking for a more legible schematic. Anyone know what other radio shares this board?

Does anyone have the mod to convert a Galaxy single FET to a dual final mosfet?

I understand that the schematics for the Galaxy 99v is the same as the Connex Saturn CX - 33. However, what is not correct is that the cx33 uses mosfets in it's RF section. I need the schematics for the actual Connex Saturn CX - 3 3. Anyone can help, please let me know.
