The USC230 on the other hand doesn't even scan bands full of strong stuff (88-108, TV, DAB, Airwave all absent), so may be easier to work with. One of the new DMR standards is continuous carrier I believe (base leg, if not mobile) so those bases may come up, but I haven't checked yet.Ĭlose Call is probably far superior if the strong broadcasting band segments can be screened out, but that looks complex from what I've seen of the 3500's manual. I've had 390 megs TETRA bases appear before. Come to think of it, I haven't checked if the new 3G stuff from the same site would overwhelm it ![]() Likewise if it's a shared site, or dual band 900/1800. It did sometimes lock onto GSM cells when everything from the cell was contained on one RF channel, but when calls are in progress and another RF "traffic" channel is in use, then there are two frequencies active at once and the counter doesn't stand a chance. ![]() I have an old counter like that which doesn't get much use because the batteries aren't holding much charge any more and I haven't got around to opening it up to replace them. So, the opto will be useful for finding the local taxi firm or radio amateur, but pretty much useless for anything else.Ĭlose-call is the same principle, but built into the radio, as opposed to being external. The american system now use apco digital as the standard, and some scanners are now able to listen in on that mode, whereas in the UK, Airwave is the accepted norm, and cannot be deciphered by ANY scanner on the market (unless you have the source code or work at GCHQ!) If you tune your scanner around nowadays, the signals you'll hear are mainly digital, and won't be able to be demodulated with your scanner. The main use is for FM signals, and therefore, not a lot of use now all the services have migrated to digital.Īs you'll know, many digital signals, also incorperate frequency hopping (bluetooth etc), so the opto will not have a fast enough 'gate time' to capture the frequency, and if it did, by the time your scanner has tuned to the frequency, the signal's already somewhere else on the spectrum! No, the optoscouts are just a frequency counter with the ability to lock onto a signal and then send the data to a compatible scanner (AOR etc) to tune it to that frequency. ![]()
