If you do an initial READ of your new radio and save this as its default file, then CHIRP knows what radio you are using, from that point on.

Just got mine today, I'll take a look and see if I can find something tomorrow.

The point about these cables that hasn't been made clear is: there are a lot of different cables for different radios with different programming or mic/speaker sockets. The most common is the two-pin "Kenwood K-1" style used by most Baofeng (not all) and many other brands. Yes, a good FTDI K-1 cable is about $15. The price you are quoting is for the proprietary (but outstanding) software produced by RT Systems, AND their software, in a bundle. Their cables supposedly had some sort of special wiring or chip inside that was required to use with their software (a form of piracy protection). However, once you buy a bundle, you can use that same cable with another compatible radio and just buy their software for less money. They are a small, USA-based company that writes and supports their software, unlike the terrible software that comes with CCRs. So, a legitimate comparison is between a good, reliable, non-RT Systems K-1 cable (~$15) vs. your $11 cable. It's a small difference to pay for avoiding reliability or compatibility issues later.

Yes, while some codeplug software has separate entries for the transmit and receive frequencies, CHIRP uses the receive frequency and the you input the OFFSET: usually 0.600 MHz on 2 Meters and 5.000 MHz on both 70 cms and GMRS. Then you tell the radio which direction to go with the transmit frequency: On GMRS it is always + so that it receives on 462.abc and transmits on 467.abc; On 2 meters and 70 cms you must look at the information about the repeater as published to determine if the OFFSET is + or - I think CHIRP has a "how to" guide somewhere... GOOD LUCK!

Commercial radios can frequently do this - I have this set up to page my family in case they want to keep the radio muted from the every day chatter on the repeater, or I need to alert them when they're away from the radio. Take a look at 2-tone paging; it's robust and plays nicely with weaker signal strengths which is why it's popular with the various public safety agencies still on analog (it's the two long beeps you hear before the buzzer goes off at the fire station). Other options that can do this include DTMF and AFSK (MDC/FleetSync) signalling. edit: see http://genave.com/two-tone-paging/

Yes, it appears that Matt has been programming in Public Safety channels, some above 500 MHz) and not Ham repeaters. The Second example shows some 2 meter and 70 cm Ham repeaters used here in Los Angeles and I will email it back to you to try out in your Baofeng and see if it remembers the frequency shifts for repeaters:

I'm not sure what the issue is for sure, but perhaps the frequencies you're trying to add are outside of the radio's permitted frequency range. If so, the radio could be rejecting the programming you're trying to add.

Pretty sure Crestline .575 is not linked.. If it was you would be seeing everyone complaining about the non-english long-talkers on it all day with out ever ID'ing with a callsign.

I originally had 3 distinct K-1 cables: 1) an FTDI-chip $22 cable that I purchased on Amazon for my original Baofeng UV-5R, UV-5RHP, and tri-bander UV-5Rx3; * 2) a chipless cable that came with my Radioddity RD-5R DMR HT; and 3) a RJ-45 cable that came with my Anytone AT-779UV mobile radio All of them work fine on my Mac when using CHIRP and in Windows XP inside Parallels on my Mac for the RD-5R and 779UV. *This same cable works find with my subsequent additions of the Pofung P15UV (a Radioddity GM-30 clone) and the ham radio version, the TYT-UV88 (both using Windows software the UV88 can also work in CHIRP) I am contemplating getting the BlueMax49ers FTDI chip cable for $25 for my Yaesu FT-857d, which I was told will work with CHIRP.

Chiming in on the cables. I purchased the RT Systems cables when I purchased their software. I am able to use their cables with the Wouxun software and the RT Systems software. I have cables with the Kenwood-compatible connector for the HTs, and one with the RJ45 for use with the KG-1000G. So now the Wouxun cable stay in storage and I am only using the RT Systems cables.

In my Jeep I mounted the radio under the driver seat and the front control panel is mounted on an arm attached to the passenger grab handle
