Travel Tones, PL/DPL differences

[wabutter]

I have tried to research this through the forum, so if The is redundant I apologize up front. I am new to the GMRS world and have explored the process of setting up radios for use on local repeaters. Of course PL codes and DPL codes are abundant, but some repeaters also indicate a Travel Tone. I think I understand the PL/DPL tones, but the Travel Tone is confusing to me.

 

Is the travel tone used in conjunction and as an overlay to the PL or DPL tone?

If not, how does it differ from the PL or DPL Tone?

Is the a field in the Chirp sotware that is specified for the Travel Tone?

 

Thanks in advance, if there is an obvious question I have not asked, please expand on your answer.

Thank you so very, very much. I deeply appreciate this.

And D411N also means the same thing.

The different terminologies can be confusing, especially when a manufacturer uses something completely different and you have to look it up in a table.

Yes it can be confusing. At least Midland puts a chart in their manuals, that does help until you learn the codes.

There's no reason these days for a repeater to have a long "hang time" since the main purpose was to avoid wear and tear on tube type finals by constantly being keyed on/off rapidly. My repeater is programmed to have a 1 second delay before dropping carrier.

Sure there is.  A wait time for someone to answer so it doesn't unkey and then rekey quickly.  It's not as bad but no matter what start and stop produce wear and tear even on electronics.  And having a 2-3 second hang time gives your party time to respond without the transmitter going off and then back on.  It certainly isn't the same wear and tear as a large relay and tube system.  But electrical spikes in transistor circuits can be fatal.

Pretty good chance that the repeater owner knew about the issue that Midland users would have, and chose to purposefully split the codes anyway. It's considered to be a cheap and effective way to keep "lesser" radios off the system.

 

I'd upgrade to a commercial radio, and sell off the Midland.

My $25 Tidradio H3 does split tones.  I have my repeater with a analog receive and a digital transmit.  Mostly don't because of the interference issues I have at my house, nothing to do with trying to keep people off.  But it's a private repeater so it doesn't matter anywho

We have a longer hand time set on our 2m Motorola Quantar 125 for this reason.

The Quantar 125 has a pretty high spike in amp draw when it firsts starts transmitting. The spike is fast/short enough that amp meters can't get a good reading. This caused us some issues with our Renogy inverter. The repeater would cause the inverter to throw a ground fault error and shut down. Our fix was to have the Quantar plugged into a line conditioner and the line conditioner is plugged into the inverter.

My repeater has a 3 second hang time. Also, I use DPL 047 in/out and the station operates narrowband.

Your radio  - mxt105, isn't repeater capable.  You can monitor the frequency the repeater is broadcasting it's id on with Morse code; that's what your hearing but you can't talk or bring up the repeater because the radio you have doesn't transmit the alternate frequency required to key the repeater and make it rebroadcast  your  transmission on the same frequency you hear.  Two different frequencies 1. broadcast and 2. transmit.

There are lots of radios that are repeater capable.  If you're coming from cb radio you have been talking on what called simplex - one frequency (channel).  When you start getting into repeaters to extend your range you use two frequencies - transmit and receive.  

Be cautious how you spend your $ on radios it can really put a drain on your wallet but not necessary give you what you want.

I would suggest you look into getting a ham radio license if you like radio talk especially in Maine, you can easily talk for 100s of miles over the network of repeaters.  Most amateur radio operators are welcoming to new hams, we even have nets(group talking sections on the air -like meeting up on the repeater to chat) that help newbies learn.  Last night the Portland repeater - 147.090 group had the newbies roundtable net at 7p.m. to talk about grounding your station.  It had about 10 check ins.  The technicians(beginners license) is pretty easy to pass with a little study and opens up a world of bands and fun.   Check it out - lots of clubs and activities for amateur  radio or send me a pm if you want more information on getting licensed.  

Great Information! I am currently studying for my license. Yes, I listen to the Nets Hear in CT and the reach is far. I know that the Bears Club repeater has a far reach up north and into Rhode Island at time.  I can't wait to get my license!

If you are looking for a way to use a "travel tone" on your radio when YOU travel, so you have access to the local repeaters, then I would suggest that you set up additional (new ) channels on your radio, with the same channel numbers that you use at home, but program these with the "travel tone" and use those when traveling.   You can name the new channels as T-20R, T-2R1 etc.   Whatever will help you differentiate them from your 'home' channels.
