The 3500XLT is not particularly user friendly for inputting data, requiring constant turning of the selector knob to find alpha numerics. The easiest way is to take advantage of the ability to connect to your PC or Mac. Get a connection cable. Mine came with a serial port connector, so I had to add a serial/USB adaptor. Intermediate Frequency Exchange – Changes the IF used for a selected channel/frequency to help avoid image and other mixer-product interference on a frequency. For example if you're a mil airband listener you can setup a group profile to include you favourote airfields, control frequencies, JTAC etc. When you want to Butel ARC536 basic software for Uniden UBCD3600XLT, BCD436HP, BCD536HP, Digital scanner receiver. ARC536 is the best-selling software for Uniden flagship scanners and it allows users to expand the functionality of their UBCD3600XLT scanner. It also includes the most versatile and feature-rich editor available on the market. This Version 2 software is compatible with Windows 7/8/10/XP/2000 and Vista. This software's features include the following:

Control Channel Only Scanning – With Motorola trunking frequencies, you do not have to program voice channel frequencies. I'd be grateful to anyone that owns either of the above scanners (or even better, both of them!) if they'd give me some honest opinions. Allows you to organize your Systems into Favorites Lists. The scanner will scan multiple Favorites Lists and Full Database at the same time. Radioreference conventional and trunk system imports thru Sentinel (Radioreference import requires an additional subscription and isThis scanner can receive both civilian and military aircraft transmissions as well as receiving many more frequencies such as emergency, marine, amateur (ham radio) and other communications. You can program the scanner to alert when you receive, a Channel or Unit ID, a Close Call hit, an ID is transmitted with an Emergency Alert, or a Tone-out hit. For each alert in the scanner, you can select from 9 different tone patterns, 15 volume settings, 7 colors (white, blue, red, yellow, magenta, green, cyan), and 2 flash patterns.

I use DSD+ to decode the control channel data to see what channel numbers it sends the calls to and then try and find that voice channels frequency by using another analog scanner to listen which frequency gets active with DMR signalling, and enter the channel number divided by 2 in the scanner. Searches a range of frequencies to find unknown radio traffic and automatically records audio from and logs new channels for later review.

I've been hankering after one of the two choices above for a while and now is the time to pull the trigger on one of them. Changes the intermediate frequency used for a selected channel to avoid image and other mixer-product interference. The UBC3500XLT claims in its specifications to be able to deal with 6.25kHz steps although its frequency only gives four decimal places. To my knowledge, it is incapable of tuning exactly to 6.25kHz offset channels as for instance used with PMR446 radios although in practice, this does not affect the listening quality. Duplicate Input Alert – Alerts you if you try to enter a duplicate name or frequency already stored in the scanner. BCT15, BCT15X, UBC800XLT, UBC3500XLT, BR330T, UBR330T, BCD996T, BCD996XT, BCD996P2, BCD396T, BCD396XT

Multi-Level Display and Keypad light – Makes the display and keypad easy to see in dim light with three light levels. When using a scanner you can either use the 'Search' mode where it searches through a range of frequencies until it stops when it finds a transmission for you to listen to, or use the 'Scan' mode where you store specific frequencies into the scanner and it will just scan through these frequencies until it finds a transmission. PC Programming – Use the Sentinel software to manage your scanners Profiles, Favorites Lists, and firmware updates.

It will take some effort to get all the scanner settings dialed in but I'm sure you will be able to do it if you first log all control channels and then all voice channels and their color codes and preferable also the system id and channel numbers. Red Dragon wrote:I'm told the 3600XLT is "over complex", and basically looks to have all the bells and whistles, where you can programme the frequencies onto a memory card (not sure what type) and insert it into the scanner. Scans APCO 25 Phase 1 and Phase 2, DMR, Motorola, EDACS, EDACS ProVoice, LTR trunked systems. As well as conventional analog and P25 digital channels.
