Question: What is the maximum distance this unit can reasonably transmit?
Document: This is one purchase that I made! This radio is like a Yaesu 8900 and all wrapped up in one little handheld unit!
Know your favorite Freq? Type it in and away you go!More goodies, are you a MARS operator? Don't know what that is? Do your homework and check out the MARS/CAP mod for this radio and extend its already amazing reach!Not a HAM operator yet? No worries, just lock-out the transmit option and you can scan the waves for chatter all day! I HIGHLY recommend this radio to those can afford it. You will not be disappointed.
If you are looking for a very sturdy HT radio, then this is a good choice. There are less expensive choices out there that accomplish the same thing, but I have had this radio for 8 months and it is very strong. I keep it as part of my bug out bag because I know it will work even if wet. I got the stubby antenna for it, as well as the microphone with GPS unit, as well as the extra capacity battery.
It can receive almost anything from DC to daylight, but it will NOT pickup Single Side Band, nor will it transmit SSB. For VHF/UHF on FM it works great. I always get full quieting even on 1W output when in the basement to the repeater (it can output 5W). The repeater offset, and tone frequency adjustment is within easy reach. I was able to learn most of the essential functions within a day of playing with it.
I really enjoy this radio and all the features it has. I have an aftermarket antenna (Diamond SRH77CA) to help get a little more distance and clarity from some of the further out repeaters. The radio looks small in the pictures and it is a bit of a small radio compared to my other radio. It is almost wallet sized. I found that after reading the manual while toying with it at the same time helps to learn this radio quicker.
Works very well make sure yah get the gps and adapter and a 2000mah battery and you will be very happy all the other suff is nice too
Works great. APRS is reliable. Only gripe is that output for speaker is Yaesu's own weird adapters. Get the extended larger battery for sure. Wish the mod allowed TX on aviation band, however, it's a hassle to own multiple almost identical radios.
This is a great radio, for those of you that are wondering if you should buy it or not. If you have the money to buy it then buy it. Once you get past the programming its a blast to use. Make sure you get the programming software and cable made by RT system, it makes it real easy.
This Rig is a must to prepare for uncertain future. Remember to protect your stored electronics in a small faraday box/container. Walter Cronkite a ham radio operator himself has said many times, HAM IS TRULY THE ONLY FAIL SAFE COMMUNICATION IN THE WORLD. When all system s fail Ham Is there!
This Amazon Prime ad calls this Yaesu VX-8DR HT a "Quad Band" transceiver and prices it at $494. Another Amazon Prime ad calls the same exact Yaesu VX-8DR HT a "Tri Band" transceiver and charges about $50 less. I love the radio, but Amazon owes me an answer, and possibly 50 bucks.
Answer: About five miles simplex and with the stock antenna ,and to most repeaters I my area about 20 miles with a readable signal . But this is typically the case with all vhf uhf transcivers with 1 to  5 watts for its size its simply amazing it can do this .
