    PM1500 Blowing Fuses

    I have a Motorola PM1500 that is blowing the inline power fuse every time the power is connected to the radio. This started occurring after the truck that the radio is in was jump started. I am thinking that something was damaged within the radio causing the positive connection to go to ground...

    SDS100 battery issue

    I bought an sds100 about a week ago and I love it but I think it may have a battery problem. I get about an hour, not even like 45 minutes just on the battery itself and it doesn't matter what I'm scanning, while the big battery is boasted to last around 6 hours. I fully charged it to see if...

    Best way to determine real transmit power for FRS radio?

    Hi, I am trying to find FRS radios that have the most actual transmit power within the limits (0.5/2W depending on channel). There is an old thread asking a similar question with a couple of recommendations here: Seems like the bigger names like Motorola and Midland do not market or publish...

    Homepatrol 2 & Eneloop Pro Batteries Issue!

    Hello all, I typically use the Eneloop 2000 mAh white batteries in my Homepatrol 2 scanner. I decided to pick up some 2450 mAh Eneloop Pro batteries, thinking I'd get a little more time in between battery change-outs (I don't charge in the scanner). Well, the Eneloop Pro's won't power up the...

    SDS-100 Color Power consumption

    The customizable color display is nice but it's not a necessity for me. I'm wondering if the color display consumes more power than the black and white and, if so, is it enough to matter?

    AC or DC Power Supply?

    Hello all. New to the forum, not new to radios. For years i've been running an external DC supply (Astron, homebrew, etc.) to power my scanners and Ham rigs. I'm not a fan of switching supplies, as they're over-prone to rf hash. What's the consensus on here - use a small wall-wart (like...

We are going through and doing inventory of these radios and just about all of them have a loose battery causing the radio to shut off and on.

    TRX-2: Mobile installation

    I purchased a TRX-2 specifically for the remote control head feature to install it in my daily driver but in testing it became clear that you run the risk of corrupting the SD card if you just drop the power when you turn the car off. For those of you that have installed the TRX-2 in your...

    Can I auto power on the CDM1550-LS+?

    I see the option in CPS but it is grayed out. I know it's possible for these to turn on with vehicle power, as our FD uses them, but mine seem to not let me do that. I got mine used on ebay through some police department.

    RS Pro-106 Power Connector

    Does anyone know for certain the specications for the power plug which goes into the side of the radio? It appears that it's a 4mm barrel, but I'm unsure of the center pin. Manual doesn't say. I'm trying to make a custom power cable for my radio.

    With so many types of batteries on the market now (AGM, LIo, lead acid, etc.) I'm at a loss as to what is best to use as a battery backup for my ham radio transceivers. I want to set up a battery back-up, maybe a small bank of batteries, that will be outdoors with the power lines run through...
