I am looking into getting a Nano-Spot to use for DMR and D-Star, I will be using mostly while traveling. I am wondering if any of you guys know a good UHF Frequency to use nationwide. I don't want to take a chance on interfering with any repeaters while traveling. Most of my traveling will be up the east coast, FL to OH. Thanks in advance!

Something in the 438-439 MHz range will get it done. 438.4375, 438.3325, etc... but your radio running 1w shouldn't present a problem. HTH.

FWIW the ARRL 440 bandplan -- American Radio Relay League | Ham Radio Association and Resources -- has 438-444 identified as "ATV repeater input with 439.250-MHz video carrier frequency and repeater links" hence my suggestion -- based upon recommendations to me from friends who have been on DMR for 6 or 8 years -- of hiding the hotspot in the 438-439 range. In this crowded area of the USA, I would stay away from putting a hotspot on anything above 440 where analog, DMR and D-Star repeaters abound. I would think the likelihood of running afoul of the few ATV repeaters with your 1w radio and 10mw hotspot is minimal. HTH.

I'm debating between the XPR 3500 or the XPR 7550 since I am going to go with a Nano-Spot, originally I was going to go with the XPR-5550

I like the price of the 3500, but the big screen on the 7550. They both have a bunch of options I would never use haha. Tough decision

I live on the Canadian border 430-440 is restricted due to Canadian Government use .most of us running ad hoc networks of hotspots use 446.125,there is no direct digital action of any mode and due the distance between us ,we don't interfere with anything ,including each other ,but we know if we are in simplex range and want to use digital that's the go to frequency, there might be a few antisocial guys running on different frequency that we dont know of course but it's doubtful because we are all pretty friendly and aware of what's going on .

What restrictions on 430-440 MHz up there?

FCC Part 97 mentions limitations for 420-430 MHz north of "Line A" and around 3 cities (Buffalo, Cleveland, Detroit) near the Canadian border per 97.307(m) - a copy of the Part 97 text is at:

http://www.arrl.org/part-97-text

In Canada, the 70cm amateur band is 430-450 MHz, per Schedule I in the RBR-4 document (one of the documents that make up the Canadian amateur regulations):

http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf01226.html#t1

There are other restrictions in Part 97 regarding auxiliary stations and repeaters in the 70cm band (i.e., no auxiliary stations or repeaters at 431-433 and 435-438 MHz per 97.201(b) and 97.205(b). Is there local bandplanning that encourages hotspots to stay above 440 MHz?

73!

I am on the lakeshore in Erie/Lawrence Park,sometimes i can work machines in Canada better then local,VE3MMX and our local machine is going to do a 440 link like the old days ,Mike and Lee go back 30+ years together ,it's only during the worst of the worst of band conditions that we can't work simplex ,my QTH is right off the shore ,if there was a road less than 1/4 mile ,You know like Sarah Palin "I can see Russia on a clear day " type thing ,i could probably see Canada (once my cataracts are removed [i see smoke everywhere, no wait thats just my eyes,LOL].
