Does anyone make a dual-listen walkie talkie?

The VX-7 should fit the bill for dual FRS/GMRS reception only.

Thanks for the reply. I don't see frs/gmrs listed on the Yaesu VX-7 stat sheet. Are you sure it can hear these frequencies? Essentially, I'd like a walkie talkie that can work on one channel (say, 4) but can hear if someone working nearby (say on channel 2) specifically calls me. I could switch real quick to channel 2 to respond, then switch back to 4 and go on with what I'm doing.

I don't know of anything that does what you want, BUT, if you plan on transmitting on FRS and/or GMRS frequencies you can't use an amateur radio HT to do it. Both these services require radios certified for them and there is no amateur radio that is. Additionally, transmitting on the GMRS frequencies requires a separate GMRS license; your amateur license won't do.

As long as all you want to do is LISTEN, then you can use an amateur radio to do that.

Any current/recent amateur 2m/70cm (or single band 70cm) HT should *receive* FRS/GMRS (462 & 467 MHz), however, as noted above,  for transmissions you'll need a commercial or FRS/GMRS HT, and, for GMRS frequencies, you'll also a GMRS license ($85 for 5 years -- good for you and your immediate family), as will the other operator (unless he/she's immediate family to you). See: http://wireless.fcc.gov/services/index.htm?job=licensing&id=general_mobile

I'm not aware of any commercial or GMRS gear w/ dual receive -- doesn't mean it isn't out there though.

I should clarify - THESE ARE FOR LISTENING ONLY on a ham radio, not transitting.

If you only wanted to check out two GMRS channels, look at Cobra MR HH425LI.  It's actually a marine VHF handheld (can't use the marine part on land) along with a GMRS radio.  It also has a weather alert with S.A.M.E. technology.  It's about $110.

It's kind of neat because I think, according to the specification's on Cobra's website, that it might be able to use the GMRS repeaters.

The Rhino 110 will do both FRS and GMRS as well as GPS location.

I have a couple of these and use them for both GPS and to speak with CERT and REACT teams if needed, as they both rely of FRS and GMRS radios.

You don't really NEED dual recieve.  I just loaded all the freqs for FRS/GMRS into my HT and scan.

Any cheap scanner will work also.

"Essentially, I'd like a walkie talkie that can work on one channel...but can hear if ...specifically calls me."

That's not how these radios work. Even "dual watch" or"tri watch" radios don't work this way. If you are "working" meaning TALKING OR LISTENING on any channel, you have no access to anything on any ther channel. If you want to be able to WORK onone channel and hear someone calling you on another one--you'll need two radios, or something akin to the "dual VFO" ham radios. As far as I know, you won't find that in FRS/GMRS radios, they are geared to the massmarket and cheap enough to just buy two if you need two.

If you've ever looked at the price for "dual VFO" ham radios, most of them cost MORE than what two cheaper radios would cost. Ain't gonna fly in the mass market.

The Yaesu VX-7 has the dual watch feature, But in the real world, I just use a little shirt pocket Yaesu VX-3 on scan mode, Which works really well.  
(It does take some effort to figure out what the subaudible tones are in your FRS/GMRS chosen channel selection) But then you can enter that into your ham grade hand held and not hear all the neighborhood kids talking away.

The simple scan method works well for me.  IF I had any expected radio traffic that was so very important that I just HAD to have an open receiver waiting to hear it, I would not consider using FRS/GMRS (Or for that matter ham radio)In the first place, But would go with commercial radios on dedicated channels.
