Just picked up my 5th Cobra 2000. It has the factory installed MB8719 PLL installed. How easy would it be to just had some wires and a couple of SPST to get some extra frequencies? Does anyone have the procedure for this? Thanks for any info.

Does anyone have the schematic for this base station?

Will move the channel mod over to the NF switch. Thanks...

Hello all. I have older late 1978 Cobra 2000. Works good. The modulation meter isn't doing anything when I key up and the switch is in the mod position on AM. Just curious if there is a transistor that switches this circuit on that might be bad? I have good audio out but the mod meter just...

Just got this radio. Trying to get it on 27.570.0 on USB but it won't. I do a lot of international QSO's It will on LSB but not USB. The best I can get out of it on USB is 27.571.5 I need just a tad bit more slide. Anyone know if there a mod to get a few more KC's out of it? Thanks in advance...

I have a nice RCI 2995 DX. 2006 model. LCD green backlit display. I'm having a memory storage problem with the processor/display board. Swapped out the 220uf 10V storage cap but that didn't change anything. My question is, can the LCD processor/display board be swapped out for a newer type LED...

PCB EPT360011Z Looked on google for it with no luck. This is a very early version Superstar 3900. I bought it new when I was 18 years old in 1986 Thanks for any help.

Picked up this Taiwan made Cobra 148 GTL the other day. Very clean inside and hasn't been chopped up. No extra channels either. It has a issue, no audio going through when the mic is keyed up. Also the Green/Red led does not turn red when the mic is keyed up. Also no audio coming out of the PA...

Looking for a .pdf service manual for President Washington. Uniden PC-196AB Thanks

Hello all. Just picked up a super clean President Washington manufactured in Japan in late 1977. I friend gave it to me for free. Only issue I'm seeing with it is when on SSB and the NB is pushed in signals sound slightly garbled and when the NB is off the SSB signals sounds good and clean...

Not sure if I'm posting to the correct forum. My issue I need help with. I have a in great condition Realistic DX440 shortwave receiver. It's off frequency by about 2Khz. Example 1070 Khz AM on the display, but 1072 Khz AM sounds tuned in the best. I wanted to know what the location on the pcb...

Still looking for that Ranger RCI 2995 DX expert. It's a 2007 model. I'm having a problem with my 2995 DX not holding memory and I can't figure it out. I changed out the 2 electrolytic capacitors on the display board and that didn't not fix it. Say I'm dialed on 27.385 then I'll turn off the...

Ok here we go. Just upgraded to a Mean Well 50 amp power supply. Works fantastic. Now when I turn the radio off and then back on memory is lost and display shows 24000 Mhz. So what gives? Is there a battery that saves the memory from the last time the radio was turned on? If there is no battery...

Have a 2006 model RCI 2995 DX Power Supply is bad and going to put in a HP 75 amp PSU. What is the max voltage these radios can handle? Mine has the Toshiba 2290's in it. I just need a idea on what to set the power supply voltage to. Thanks for any suggestions.
