Question about Ranger RCI-2995DX Base Scanner

1 Answer

Squeals when keyed up. Detecting talk back.

I have a 2995DX and use a Turner Plus 2 microphone. Just recently, I've noticed it wants to squeal, or even hum, like the mic gain is up to high. I tried the stock microphone on it and I try to get the modulation up with the gain, and I detect some talk back through the external and internal speaker. No special mods have been done with this radio to have talk back. I really like this radio and want to keep it for a while. I thought it might be the Turner acting up and tried to trouble shoot that, but, like I said, the stock mic is acting the same, but not as dramatic.
Please help me...

ITS JUST NOT THE TURNER MIC IT HAPPENS WITH ALL BASE MICS HAVE HAD THE SAME PROBLEM WITH MY 2995DX WITH A ASTATIC D-104 & 1104-C AND ALSO ANY TURNER I HAVE USED BUT I CAN RUN A ASTATIC MOBILE D-104M6B OR RED DEVIL AND NO SQUEAL HAVE YOU TRIED GROUNDING THE CASE OF THE RADIO IT IS RF FEED BACK SQUEAL SO MY SUGGESTION TO YOU IS TO RUN A 48 COPPER GROUND ROD INTO THE GROUND AND RUN A NICE GROUND WIRE TO THE BACK OR THE CHASIS OF THE RADIO AND IF YOU ARE USING ANY EXTERNAL AMPLIFIERS ALSO GROUND THEM AND YOUR SQUEAL WILL BE ILLMINATED

I can't get my uniden bcd396xt police scanner to talk. it will scan, but not talk


Hi Sue,

No it's not a Police scanner, rather a radio scanner.

I will scan, but not receive transmissions.

Two reasons for this:

1. Do you have any frequencies programmed in the scanner, if not, there's your first reason answered.

2. Do you have frequencies programmed but the channels are locked out? If so, there's reason 2 answered.

To unlock channels, you need to press Mon/Hold key to stop the unit from scanning. Now press mon/Hold key and as you do so, notice if you have frequencies programmed and not just a bunch of zeros showing on your display. If zeros are displayed, example: 000.0000MHz, then you need to program the scanner with your favorite frequencies, and I advise that Police should not be programmed. If you do have frequencies programmed, then using the Mon/Hold keys as stated above, go through each channel and unlock each channel using the L/O key, until the L/O icon on the display goes out.

I Hope I have assisted you with your query.

Cheers,
Peter

Radio won't key up


Microphone or output circuit problem are most likely---The 25 is a fairly trouble free radio.

The microphone is the most common issue--broken wires inside the plug connection or a broken wire in the cable up to the microphone head.

In most cases I have been able to replace a capacitor associated with the power supply, it fails when the voltage is pulled down during transmit. You're more than welcome to ship it in here.

Power dims when keyed dims lights fans ect.


your radio is trying to draw more current than your power supply can provide it, you need a power supply with higher current capability.

Will not stay on 11 meter turn it off comes back on 10&12 meter will not transmit am or ssb recieve ok. rci 2995dx.


Hello janetsue, If this radio has the blue or green screen LCD face then this is a default that is built into the radio. It depends on how the radio was "converted" when it was bought new.
It will not key up on 10 or 12 because of the default. A little more info supplied would be real helpful,,,, Let me know, Mechanic
