Hi all recently I got my Technician’s License and I would like to get a mobile radio so I can carry it in a backpack, put it in my car and use it as a home rig as well.  I am most curious about the “dual band” radios that can act as a repeater (UHF to VHF or vice versa).  Specifically can anyone direct me to resources where I can find out more about the actual internal circuitry of these radios?

@tentoes

Although I am an amateur radio operator myself, this question might be better suited to a forum or group of folks that are all about amateur radio.  While we have multiple hams on this site, your responses might be somewhat limited because of the small number of hams that make up the entire forum.

How about a local club?  And going on this weekend is a Virtual Ham Radio get together, but that is probably winding down.  And next weekend, if you are anywhere near Huntsville, AL (probably slim odds of that!), there is an in person get together call the Huntsville Hamfest.  Good places to gather information.

Here it is more for possible help using Arduinos and the like with our ham radio gear.  My biggest project was building an antenna rotator control for my towers 10 element Yagi.

hey tentoes... try qrz.com

there are forums there just for mobile, qrp, POTA, satellites and vhf/uhf

personally I use a FT60R. when mobiling I use a 30W amp and a dual band antenna

Also used it as a scanner, and have used it through the AO91 satellite from my backyard

and on the same satellite while in BC into Alaska

@ve3cga Thank you for the information!  I got a Yaesu mobile rig so I can put it in my vehicle as well as use it in my vehicle (It’s an FTM-300D).  I still don’t have it installed in my vehicle as I’ve had several in the last few years…..long story…..It’s sad to see how little the local bands are used around here in Portland….

Ooops….let me try again.  I got a Yaesu mobile rig so I can use it in my vehicle as well as use it as a home rig also to talk to the local repeaters…

@ve3cga I have been thinking of putting together a SDR-based radio sniffer for when I go fishing or camping just to see what's out there on the air, wherever I go.... I would use like a raspberry pi4 as the brains prob....

@tentoes 

when we go camping (tenting off grid) I either take my ft60R or a laptop with a RTLSDR v3 , v4 would also work

Using sdr# or sdr console or hdrsdr or if you like linux GQRX

rasbery pi would work too

but I think an old laptop with linux would be the cheapest, easy to setup & the most fuss free

I use an old dell lattitude E6410 (2G ram with a 500G ssd running tiny10,or linux on a 250G drive)

@ve3cga Yes I thank you for the recommendations!  I already have a few RPi4s sitting around, two USB SDR dongles with two inexpensive displays, but now that I think about it, a dedicated laptop just might be simpler.  I have seen a pretty wide-band discone antenna that could serve well in this purpose also.

Now that I think of it, the laptop idea sure sounds like the most inexpensive way to have that kind of functionality.  The mobile Yaesu I have has two tuners but it doesn’t have the cool (and highly useful) wide-band waterfall display that I have seen on dedicated software……I have a lot to think about….thanks for the ideas!!
