My question is: Would using a 5V/2A charger, hurt the 436HP? Scannermaster shows that the 436HP uses the 5V/1A AC Adapter USB (5V 1A) | Scanner Master And the 5V/2A charger is only for the 200? Uniden USB AC for the SDS100 (AC1278) | Scanner Master My questions: Would using a 5V/2A...

so i built this linear loaded SWL antenna, a project i found on the swling website, which involved getting a a NooElec 9:1 balun in the middle of two 15ft pieces of romex bound at the ends in a way that it effectively makes a dipole with 45ft elements. this balun is not made for any kind of...

When plugging the bc-sgps into the sds100 (or any scanner), should the power on the scanner be off and the bc-sgps plugged into the power source already? After you plug in your bc-sgps cable to the scanner, you then turn the scanner on. Or does it matter if the scanner is already on and working...

Good afternoon all! Question: All thing being equal, and hypothetically of course; for general use CB (short range), longer distance communication (25+ miles) and 'skip', is a higher powered radio (export or mod) or a linear amplifier generally preferred? Or both? Again assuming the same mic...

Happy New Year, everyone! I’ve got an XG100P with FW XLP R02A28 (last programmed via RPM 14C05) that reverts to zone 1, channel 1 each time it gets turned off and on again. The only way to circumvent this is to program the system I want to use into the ABC switch, but I change systems...

in another thread it was mentioned that a particular emergency radio eats batteries. most people don't take that into account and while some manufacturers might list specs like sensitivity or even selectivity, they never mention battery efficiency. nobody does. but it should be a huge...

I’ve had this unit for at least 8 years, bought second hand, have never had any problems, suddenly the keypad is not responding and when on either dc or ac it powers on on its own, seems like some kind damage or malfunction. I hooked it up to Freescale and it works fine I tried the F keypad lock...

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...

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...

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...

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...

I have in my possession two Uniden BCD436HP model scanners, one is mine and the other is a friends. They have had their share of run time over the past year since we purchased them, but now they don't "run" at all...…….:( I can not get them to boot up and I have tried everything I can think of...

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?

What scanners and ham radio's (mobiles) can be vehicle mounted and will turn on when I start the car without me having to manually press the power button?

I have googled and search this forum till my eyes are dry. 1.) I have a CDM 1250 that I bought used knowing that the seller told me there was no speaker audio. Besides RX/speaker audio it works and transmits fine. Seller stated it was originally used as a paging radio and he used it for a APRS...

I have purchased a few used CDM750's over the last 6 months for small projects. I run into the same problem on Low Power models as well as High power models. I'm not getting the correct RF power when I test the power out on a meter, I have tried a few different meters and antennas. Using a...

How do i get this mobile to turn off and on whenever i turn my vehicle off and on? I know this sounds lazy but i do get tired of turning this radio on and off everytime i get in and out of the vehicle. I know i would have to wire the radio into a 12 volt hot wire that would be controlled by...

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...

Hello all, We have several CP200 VHF radios currently in use at my organization. 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. Many of the users have resorted to methods of keeping the battery from...

I have a TK-2170 VHF that will not power on. I have tried multiple batteries and I can't get anything. I was programming it and I wrote the code plug and it cut off and now it is dead. Anybody know what could've happened? I really need this radio back in service.
