CP200 PL Tones

[Unit475]

I have a ??? about the PL tone setup for the CP200

My county fire channel pl tone is 186.2 Hz but if I recall right I think I heared that if its set up as a tone SQL that it will not work. It has to be set up on a tone ENC. Our fire and so channel is like that however our rescue channel is a tone SQL but will work with a tone ENC.... How would I explane this to the person programming the radio? Or dose the radio came in tone ENC to start off with???

Thanks,

Tone ENC generally means that the radio only sends PL tone when transmitting, but operates in carrier squelch mode when receiving. Tone SQL generally means that the radio will transmit PL tone as well as only open it's squelch on receive when the correct PL is received.

If everybody is transmitting PL, it would almost not make sense that you couldn't also set it up to receive the same, unless for some reason you are operating through a repeater that does not pass or retransmit the PL tone on the output side. This is not very common in commercial/public safety applications but there are several reasons why it might be done. More information about the system would be helpful.

I have no more info on the system however what you said seems to be correct! It transmits PL into the repeter however dose not transmit PL on the output. How would I go about telling a person programming a CP200 how to do that?

Have them program your TX frequency with the PL code 186.2 and for the RX Frequency, leave it as CSQ, if that helps you in a way.

Though youll likely receive some scratchy white noise that can be annoying "sometimes"

X2 what C138 has said...

Some fire repeaters are set for CSQ to avoid PL issues on receive. That's not that uncommon.

107.2 is the RX PL because that is the tone for the talk around "same a fire output with no repeter" and that is the tone you use for your scanner. So can you prog. TX= 186.2 & RX= 107.2???

I just noticed your in NC if im correct on your location anyways, if you have a buddy that can lend you his radio, you can probably go up to piedmont two way in durham or if your near a shop, have them clone the radio, makes it more simple for you unless you want more for your radio if its a personal item.

Also to add, you CAN program both the TX/RX frequency to operate on 2 different PL/DPL codes, if that repeater is set the same way for example

TX: 155.580 - PL 100.0
RX: 154.650 - PL 192.8

If the repeater was set like that and everyone has their portable set up the same way, i guess i could say your entire unit will function properly.... unless someone else has a better answer?

Well let me just give a littile more info. The dept would never let me uses a radio to clone. Kinda stricted on who has one that is the depts. So thats out of the question.

The fire channel is set up like this....
TX: 153.965 MHz PL: 186.2 Hz
RX: 154.430 MHz "Unknown about the PL"

I got to look at a Vertex radio that was being programmed. Its was set up like...
TX: 153.965 MHz PL: 186.2 Hz
RX: 154.430 MHz PL: CSQ
and it worked fine!

However on that same radio, channel #2 is the fire talk around channel which is...
154.430 MHz PL: 107.2 (No Repeter)

If you cue up on the fire channel (#1) and flip to the talk around channel (#2) you can hear the repeter...
So in that case im thinking that you can do it like this:
TX: 153.965 MHz PL: 186.2 Hz
RX: 154.430 MHz PL: 107.2 Hz

Am I right?

Ill try and make this short and as much sense as it can make for you to understand in a way i kinda tried it myself before.

This is channel 1's setting

TX: 153.965 MHz PL: 186.2
RX: 154.430 MHz PL: CSQ

If your fireground channel "Ch. 2" is simplex it would be

TX: 154.430 MHz PL: 107.2
RX: 154.430 MHz PL: 107.2

If your on ch. 2 and your keying up, someone on channel 1 will hear that "pop" or you talking since they do not have a PL/DPL code to block out the unwanted transmission but thats only if they are really close to you like by a block or a mile maybe but if they TX on ch. 1 to 154.43 on 186.2, it rebroadcast's to 154.430 on CSQ, you wont hear whatever is said on the fireground on 107.2 unless you release the PL by hitting one of the side buttons or the monitor button, however the CP200 is programmed.

Am i right about that one guys? if not im sorry.. I just thought that could be the best explaination..

If channel 2 talk around is set as PL 107.2 receive and you can hear transmissions coming from the repeater, this concludes the repeater is running split PLs (186.2 in and 107.2 out). I won't get into why this is done, but if you program radio as you stated above it will work fine.

x2 on that
