I tried bringing my scanner to one of the airshows I attended at EAFB and was told at the check-in entrance that I could not bring it in. Luckily that was back when they had parking that was near the entrance (unlike later events that used remote parking with shuttles). I was able to walk back...

For reference, my VX-6R quick charger starts off solid red then changes to flashing red and finally to flickering red before changing to green. This can take several hours.

I don’t know if it is the same problem, but one of my VX-6R HTs lost its reception on narrow band FM. Wide band FM (FM broadcast band) still worked fine. The problem turned out to be a failed ceramic filter that is used for narrow FM. Here is more information on this issue...

Hey I liked the 1970’s :)

Chrismol1, Well to be fair, the U.S. was like that too when it came to analog cell phone conversations in the 1980s when they made it illegal to listen to those specific 800 MHz frequencies. Even though all cell phone transmissions are digital and encrypted, it is *still* illegal to sell a...

I may be mistaken (I do not live in the UK) but isn't it illegal to monitor radio conversation in the UK other than general reception transmissions? https://www.ofcom.org.uk/spectrum/interference-enforcement/radio-interception "Typically, receivers and scanners can only be used for ‘general...

As a test, try powering the Bluetooth adapter with a separate USB power source like a USB phone charger. If the hiss disappears, then it could be a ground loop or noise issue with the SDS200 USB port.

That audio output power is perfect for listening to my favorite band, Disaster Area. https://hitchhikers.fandom.com/wiki/Disaster_Area

$5.99 AM/FM with earphones and armband. Also available in their brick and mortar stores. https://www.biglots.com/product/digital-am-fm-radio-with-armband/p810370584?pos=1:5 Depending on your definition of a radio, I have also seen the FM only scan tuning radios with earphones for 99 cents at...

Technically DMR and P25 Phase 2 use the same audio AMBE+2 vocoder format. Since the DV1 already decodes DMR, AOR would not need to add another vocoder to decode P25 phase 2 audio. They would need to add support for decoding the P25 Phase 2 voice channel protocol to extract the voice audio...

The SR30C is more of a replacement for the BC75XLT which I believe has been discontinued.

Regarding transistors Q3 and Q4. While we don’t have access to a schematic diagram for the SDS200, it is *possible* that they are performing a similar function as Q1 and Q2 do on the handheld SDS100 model. If this is true, these can be damaged by exposing the scanner antenna to high RF fields...

According to this thread, it may be possible to install Sentinel and ProScan on an ARM-based MAC. https://forums.radioreference.com/threads/sentinel-on-arm-processors.424982/

Or the Hewlett Packard HP-12C Financial Calculator which has been in continuous production since 1981. https://www.hpmuseum.org/hp12c.htm

The FCC did not request those ranges to be blocked. A number of other Uniden and Whistler scanners cover those ranges that are missing in the BC125AT. It is possible that the bandpass filters in this model did extend into those missing ranges. It just seems odd that they are missing especially...

It’s a shame that Uniden put in this restriction and limited the air band coverage on an otherwise outstanding analog scanner.
