Aor ar 2500 software

Scan and search rates are fast, about 36 per second, if frequencies within a bank are kept reason- ably close together. Search increments are 5, There is a 9 pin type D connector on the rear panel for external computer control, and AOR had software available, and aftermarket scanner control software may handle this unit. The antenna connector is a BNC type, and there is a switchable attenuator.

One of the first things that a user will notice is that the channels within a bank are not numbered, and that the AR will sort the contents within a bank in descending frequency order. When a bank is full, the word "FULL" will appear on the display, and one or more of the old channels will have to be deleted.

Operation of the is quite a bit different from most scanners, but is not difficult to master it. The manual is written by ACE, and is well-written and easy to follow, but lacks in any real technical data about the radio. Media New media Search media. Classifieds New listings. Log in.

AR Software. The new AR, made by Fairmate, for A. Compared to the earlier mentioned radios, which were built like tanks, the is on the light and flimsy side. Feels more like a toy. There are 62 banks of 32 channels each, plus another 16 search banks.

Scan banks can be scanned separately, or linked together. Scan and search rates are fast, about 36 per second, if frequencies within a bank are kept reason- ably close together. Search increments are 5, There is a 9 pin type D connector on the rear panel for external computer control, and AOR has software available.

It covers in detail how to program and control the radio through the computer port. There are about seven pages listing the contents of all preprogrammed channels, which are all the commonly used public service frequencies in use in the USA.

I ran a simple PC program through it and was able to load in frequency and mode, and make it search and store between two chosen frequencies, with the freq step computer selectable.

I brought it into the lab and put it on a signal generator, to check out the sensitivity and make some meassurements in a nice "friendly" world where there are no strong signals to overload the front end, none of the usual noise and other electromagnetic garbage to cause confusion.

Sensitivity, under these ideal conditions, was surprisingly good, about. In spite of the maunfacturer's claim of continuous coverage from 1 to MHz, my unit serial number operated only from 1 to and - MHz. It will program anywhere from 0. The radio was slightly off frequency, but there is a simple adjustment to take care of this, which I'll get into later. In the real world of RF pollution and strong signals, the AR's performance suffers somewhat, as we will soon see.

Image rejection in the - MHz range is poor to outright terrible, varying from a modest 5 dB to -5dB yes, the image is stronger than the intended signal.

The images that appear are Signals that are on or close to the The NH State Police on Such problems could exist due to poor shielding and filtering. Out of scientific curiosity, I carefully opened the radio to get a look inside. The only shielding was around the VCO part of the synthesizer, and that that was soldered up as tight as a copper kettle. Everything else was wide open, and exposed to any RF that happens by, whether from the antenna, through the plastic case, or internally generated by internal oscillators and by the logic circuitry.

The front end is definitely broad banded, with no pre-selection or real filtering. All the RF and analog circuitry is on a densely-packed double sided board, with extensive use of surface mount components. The logic and display circuitry are on two small, densely packed boards attached to the front panel.
