Hi Thought I would comment on this radio as I use one of these rigs in my van for HAM uhf-I am a bit of a UHF radio junkie.
I have the full programming manual for these radios and they are only too clever-Basics is you can do all the basic 5-tone stuff and included are multiple call -answerback divert functions. To truely try everything out on this radio will take you a month of sundays (correctly a lot longer) If you have no prior understanding of the general functionalities it can take a lot longer. I also have the portie which is the TK349 which uses the same program which is really good. Over and above you can write your own program within the intelligence where to tell the radio what it can do and how it must act when codes are received. Foer example you can have a number of events written by you-decode number XXXXX wait then reply with x number of XXXXX strings OR not ,alert the radio send external alert message divert the radio onto a frequecy or make the radio go into scan . Just an example but as mentioned before your own imagination determines how you want to impliment these many features. As far as these radios they were certainly the better of the five-tone capible radios in their times. If you are stuck you can give me call for specific help and I could scan a page or two beraing in mind the programming manual is several hundred pages with examples of writting non-standard code strings etc. For the beginner you must decide on a code standard. Many emergency services such as Police and Ambulances went with the ZVEI-1 standard.standard of 70ms per tone The large Electrical company went for EIA tones are shorter 33milisecond per tone . We in the Telecom company at the time decided on ZVEI-1. One must remember that a 12345 in one standard will not interact with another atandard of the same number thus deciding on a common code to start is very important. Perhaps hams should decide some where to adopt a standard -I use ZVEI-1 and some EIA for voice pagers that I have played around with.(The ones as used in hospitals etc-make great devices for emergency situations. One important area of concern with single tone signalling remember it is in-band thus take note of any system in-band signalling that takes place such as DC-Remote on Micor-other Voting systems that use specific tones to do the switching DC-landlines or voice recorders , the use of filters will negate some of your tones being used so careful implimentation will do justice Best of luck in your quest-I also have the tone standards for all the different formats. regards Bradley Glen ZS5WT --- mch <[EMAIL PROTECTED]> wrote: > Well, I do know Europe uses a lot of 5-tone > equipment, but the fact that > you had a lot of it was missing from your original > post, so don't be > surprised that your replies were skewed based on > that missing fact. > > I'm not 100% positive, but I THINK you will find > that there are two > 5-tone formats - that used by pagers (older ones) > and that used by the > European radios.
