Do you remember the Yaesu FRG-9600 (Also known as the Yaesu FRG-965 & Sommerkamp SRG-8600DX)?Just something on the Yaesu FRG-9600 for people that aren't aware of this reallycool VHF/UHF communications receiver. In 1985 Yaesu decided to release an advancedpiece of hardware for the commercial & ham radio community to receive from 60 MHzto 905 MHz in all modes (AM, FM Narrow, FM-Wide, LSB, USB and CW). It included 100channels, 5 bandwidths, tuning steps starting at 100 Hz and had computer controlwith squelch and signal level output on it's CAT connector (Even the ICOM R7000don't have these as standard interface outputs). Java 1.4.1 for mac pro. This is more of a communicationsreceiver than a scanner but with the computer control, the features are open toall possibilities and makes it software upgrade-able via computer control to do tasksnot imagined in 1985. Remember, this is all back in 1985 (over 30 years ago).The Yaesu brochure stated' The YAESU CAT System provides a direct control linkto the cpu in the FRG-9600, allowing operators with personal computers to addvirtually unlimited computer control functions in software: such as multiple,organized memory banks; automatic tuning; and customized scanning systems;using most any personal computer and a Yaesu FIF CAT interface unit.' Yaesu madethe FIF-65A for Apple, FIF-80A for NEC PC8001 and FIF-232C for IBM computers.One last thing, the Yaesu was first to market for a Ham / Commercial VHF/UHFall mode communications receiver with no usual frequency gaps and includedthe 800 MHz band.
It was also one of the first computer controlled scanningreceivers made. The ICOM came out a few months later with an even more advancedVHF/UHF communications receiver that covered up to 2000 MHz and was the standardset for many years to follow. Both these receivers are in a different class thanthe typical scanners of their time and many are still in use to day, even ingovernment and surveillance agencies. The FRG-9600 is more common in Europe thatthe USA. I didn't know they made an interface for the Commodore 64 or that software was made for it but I know it's one of the easiest scanners to write software in with the BASIC computer language.
The scanner uses just two commands. The frequency set command and the mode set command. The computers knows if it found a station or signal by reading pin 5 (Signal Level) or pin 6 (squelch). Pin 6 is easiest to read because it's either high or low for squelch closed or open. Yes, this was true for many people. While the FRG-9600 is a fantastic receiver it did have problems especially with quality control of the first batch of radios made.
I remember reading some vintage reviews where some reviewers gave it a high rating and others where they just had all sorts of problems. Most were fix with an alignment and they gave good service afterwards. Also to make matters worse, the radios used 3 different tuners in it's design over the years. Again, some of the earlier ones came right from the factory out of alignment. I don't believe Yaesu made the tuners but sourced them out of house.Most people I know that had problems with them (off frequency, overload, adjacent-channel problems, etc) were fixed with a proper radio alignment. I know that the radio can overload with really strong signals but that happens with a lot of receivers / scanners in this price range.The ICOM R7000 is superior to the FRG-9600 in most aspects but in it's day, the FRG-9600 was the closest thing you could get to a R7000 without paying the R7000 price.As for the quirky/clunky scanner features.
It has some very advanced features for it's time BUT they missed two main features. When scanning memories, it can't scan the full 100 memories at one time but only 1 bank of 10 memories at a time. The second feature missing is when scanning, it only stops on an active frequency for about 8 seconds and then continues on.If you want to hear a transmission that lasts longer than 8 seconds, you have to push a button to hold it. It doesn't stop until the transmission is finished and then resumes. This looks like a problem and they should have had two scan modes, one like a regular scanner and this one.What looks like a problem was really designed that way for a good reason. This is first really a communications receiver so the memories are designed to be tuned with the knob to monitor a single channel. The strange scan mode is made really for searching wide ranges in the frequency range that can also have non-voice frequencies or other signals that can stop the scan/search process.
At that time, radios were in the infancy with Yaesu's AF scan, Voice Squelch Control where the receiver checks received signals for voice components or the more modern data skip options. They did work but could be fooled.This way, if it stopped on just noise, pager or a data signal it would just continue on after 8 seconds until you heard a station that interested you and then you would press a button to hold it. I wish some modern scanners had that feature (I think ICOM does have this feature even now where you select a time and it resumes after that preset time).The Yaesu was really meant to be controlled by a computer as the manual suggest to write your own to do what you wanted it to do. This radio had both a squelch output and a signal level output on it's CAT interface that even the R7000 never had on it's CI-V interface. Blankey jet city bang rar. The R7000 never had a factory designed way to report a signal or signal level back to a computer.
Some software used the tape recorder output to relay when the radio found a signal to a computer.If you still have your FRG-9600 and are having problems, you would be surprised what it may perform like if you get a full alignment done on it. I heard of a government department that still use a bank of these radios.
Their is over 10 software programs out their for this radio and with the manual and a little help, you could write a program to do what you wanted it to do including some modern features. Under software it can scan 1000 channels with alpha tags and stop on a frequency, resume after the station stops transmitting with any delay (1, 2, 5, 10 sec, etc).
It can also search with frequency steps starting at 100 Hz and scan memories of unusual frequency off-sets, etc. All under software that it can't do on it's own.
