Radio progrmming

[metallitera]

i know all radio systems are different, but im gettin a Puxing PX-777 PLUS for a backup to my FD one, its UHF.

What my question is, i noticed that the RX&TX freqs are different(one is for repeater), so for the talk about channels, do you use the non-repeater frequency?

and what are the tones? what happens is i dont program them in?

i have not had a chance yet to get one of those chinese radios yet, but usually if you are using a simplex channel (same RX as TX) you can program in the same for both. Other times, you may have select duplex and put in an offset if they dont give an option for TX and RX.

Regarding the tones, if you dont put in a tone, you can receive whatever is being heard on that freq, but if you are using this to transmit, i doubt anyone woudl hear you since you are not TX'ing a tone. Your radio tech shoudl be able to give you this info adn you can program it yourself or have them do it.

Can you take a screen capture of the software so I can see what options you have?

havent had a chance to use it yet, as i downloaded it free from the site and ordered the radio today. i dont see where i can enter text tags for the channels, so im gonna try & program the channels myself on the radio with the keypad, but will prolly get the cable anyway. i program my scanner with the software and like it alot better, bein able to save different channel banks and change em out every so often very easily.

The tone choices are drop down boxes.

RX Tone has OFF, 67.0, 69.3, 71.9, 74.4 and it goes on like that, then to Do23N and a whole list of codes that start with D and have numbers & letters.

TX Tone has what looks to be the same thing.

here are some screen shots, let me know if you want more:











I'm assuming that the talk around channels are done by entering the freq in the TX side, instead of the reperater, and transmitting as low power?

what about busylock, PTTID, opt signal, and wide narrow?

also, do i need to put it anything for the RX tone? or the same thing for RX&TX tone?

you may want to stay away from your department radio technician. Many of the new chineese radios are not FCC type accepted and illegal to use in the United States.

Talkaround can be set by making the Tx and Rx frequencies the same. Just make sure the Tx tone is the same as the Rx tone. I believe that the power setting would be based on your FCC license...you'd have to find out the power of the radio and what your license will allow.

The model i bought is FCC liscensed, i looked at numerous models, and it seems to be the only chinese radio that is.

power setting is 1w & 4w. i read on another post that if i dont have the TX tone that no one will be able to hear me, if i dont set the RX tone, will i be able to hear everyone else?

Correct. If you don't set the Tx tone you will not open squelch on everyone else's radios (or the repeaters if they require them when not in simplex mode).

If you do not set the Rx, you WILL hear everyone else. You will also hear any other agencies that use the same frequency (if there are any) but a different tone. Basically, you will receive ALL transmissions on that frequency regardless of tone. You may have to adjust the squelch (may show as CSQ) setting so you're not always hearing static when there's nobody transmitting.

PTTID transmits a signal that shows what radio is transmitting. Not sure what equipment is needed to see that code, but I would set it to off. The Opt Signal is DTMF (sounds like a phone dialing) and FSK (dunno anything about that). You would have to talk to the radio guys to know if you need this or not. It's an alternative way of signalling.

Busylock means:

Carrier - cannot transmit if radio is receiving a signal
QT/DQT - cannot transmit if radio is receiving a signal which matches the programmed tone
Close - no restriction on transmitting

well I got the radio and i threw a few frequencies in there and i cant receive anything. the signal strength indicator lights up but the radio is silent. i tried changing the tones to off and still nothing, messed with squelch also.

the monitor button opens the speaker up and the radio beeps when keys are pressed, so the speaker is working, just not playing radio signals.

[EDIT]
I got home and uploaded the frequencies from the software and it seems to be working. just a couple of the frequencies listed in the database for FD's are PD's.

I'll give ya'll a report of how the radio performs since it seems not many ppl have one of these foreign ones.

check the pl on the radio itself.
