If you can find a Yaesu dual band radio for the same price as a Yaesu single band radio show me because I'll buy it.
If you want to buy cheap Chinese junk feel free but your quality with suffer big time.
I've done extensive tests with my 20 year old Kenwood TM-V7A and a brand new TYT TH-7800. Considering the difference in their ages, the Kenwood does seem to be holding up well, but its "ears" have lost a lot over the years. Of course the display "died" about ten years ago, and is not repairable. I have to 'count the clicks' on the tuning knobs.
Taken together though, the "Chinese" TYT is feature for feature identical to the Kenwood, which incidentally was made in Singapore (China). As I recall I paid around $600 for the TM-V7A, and $220 (shipped) for the TH-7800. Worse, adjusted for inflation, the Kenwood TM-V7A was
$1,016.98 in today's economy!
Test Equipment: Cushman CE-5 Service Monitor, Rigol DSA815 Spectrum Analyzer, Bird 43 wattmeter
