Those Anytone 6666’s are great radios. That’s what I have in my mobile. I’m about 2 hours south of Houston and I make contacts in Australia on a weekly basis on 38 lsb. In my mobile with a at-6666, fatboy 4 pill with a 6 foot skip shooter on a workman triple magnet mount. Most of the time on side band I don’t run the amp. But if I’m having trouble getting to someone I’ll turn it on. Im not driving it to the fullest and I get voltage drop from the stock electrical in my car so I do about 380 watts rms and 700 pep with the amp. Just the radio 55 watts rms and 120 pep.Yesterday I QSO'd with Gus, 35NB001. Each of us were operating mobile. Mine is the AT-6666, coax, and mobile antenna (don't know what brand). Rogers, AR to the Netherlands, 4643 miles. Not my farthest, but definitely a fun mobile DX contact.
