Weak original battery.
Poor quality rubber on the helical antenna.
Poor fit elements.
Very good reception quality.
To date, the highest model ICOM and the highest in the world in terms of transmission range.
There is no stronger a portable radio.
• Only had it a short time. I am an Alinco fan (for ham) Icom fan commercial band. This is easy to program feels good to hold. As far as all the battery concerns I have read. Go to amazon. This radio uses the same batteries for the IC F-11 and F-21 1800 to 2200 Mah for under 30 bucks and a charger “Compatible with Ni-MH, Ni-CD and Li-ON batteries” I have been using them for a long time and no problems. also for around 30 the factory charger works on 12 volts d.c. so mobile charging is a “no brainer” So I am using the batteries and chargers I have.
• It has great audio in and out, where my friends Vertex sounds “weak” we are told the v-82 sounds clear. On my Byrd meter it shows 7.5 watts low to 7.75 high. The antenna could be better and the BNC I have mixed feelings but they have worked for ever and make external hook up easy. Will see if it lasts as long as my work Icoms. So far I like it
