Re: Static and Signal Loss

I suspect the problem won't be cable related at all as you've done the sensible ground checks. What are these aux lights? Are they 100% passive, as in you supply them with 12V and filaments light up,...

Re: Radio help

You just need some custom controllers - I don't know of any off the shelf ones as everyone needs something different, but the features are pretty common. The mode of operation is usually like this. A...

Re: Radio help

Most of the big manufacturers make dispatch controllers that let you do this kind of thing - but it sounds like your radios are programmed a bit randomly. I think you mean they are not trunked, but...

Re: Vhf antenna help

As I said Greg, it depends on the topography - but also the system. If you want direct radio to radio comms, then 5K distance is going to be difficult - sometimes even a mile will not work. Signal...

Re: Vhf antenna help

The real issue with the difference between scanner antennas and transmit antennas is their impedance. For receive, it doesn't matter - so having an antenna design with multiple different length...

Re: Baofeng UV-5R ?

Not being funny - but have you actually played with it? turn it on, enter the frequency. If you have too many digits it ignores them and if too short it just sits there. If you enter in a frequency...

Re: Tone or TSQL?

If you are the nosey type, then hearing everything solves those weird interference issues as you hear everything = sp sending a tone for those that need it to open their squelch is critical, but...

Re: Walkies for school emergency lock-down

'Discount' in a trading name shows where their core business really is. Pro dealers have the ability and time to make systems that really work properly at all levels of security.

Re: Is a License required? 400-470Mhz 5W 3.7V

What you need is to look on the Ofcom site - business light or suppliers light and you will find the licence is ?75 for five years and has a small list of available frequencies you can use. It's...

Re: Motorola BPR40 question

Volume, usually. Normal earbuds expect all the power fed to them to be hifi quality, not narrow band comms with clicks pops and blasts of interference, so when the level is turned up, they tend to...

Re: Help on Motorola Talkabout T82 EXTREME

Sadly, this range is exactly what they are capable of, and is exactly the same as other units of this type. Site comms - short range, small area. Half a Watt, small antennas and held in the hand are...

Re: Radio compatibility

If they can be set to the same frequency and have any matching CTCSS tones you may be using, then they should work fine. It goes wrong once you have digital kit that is far more difficult to...

Re: programming walkie talkie for multiple frequencies

As long as all the radios work in sensible and legal bands, then you should be able to do this. I cannot speak for the US, but some schools here stupidly use the licence exempt channels, and here...

My bad - I hadn't realised we weren't talking about the Motorolas and had moved to CB - which I know little about.

Re: Replacement Antenna's

Fibreglass body vehicle antennas exist for many bands, typically marine band, but for vehicle use you need a balanced antenna as the ground plane, as you say, doesn't exist.

Sleeve dipoles are...

Re: Motorola CT250

You also have the small problem of finding out what tone access system is in operation and duplicating that. If you have the right kit, then that's just a case of being close to a radio with a...

Re: Repeater- Distance

Realistically in reasonably flat terrain, a service area of around 20 miles for decent repeater is normal, but in hilly territory it could be more if the repeater is on the top of a mountain, or less...

Re: Kirisun Radios - Quality of the components

Re: Handheld radios for child hiker suggestions please

The honest answer to this one is always that any range over very short is often down to luck. The real physics is simply what's called path loss. So anything in-between the two antennas reduces...
