Great rig for the money. This does everything my Icom and Yaesu radios do for a fraction of the cost. The only negative I can think of is the low TX power, but it still hits many nearby repeaters.
So far, it is just what he wanted. He plans to add a higher power antenna. I may have started a new disposable income pit but he is happy so I am happy. It does all of the things he needs in a new HAM radio.
This is awesome. Goodbye to all these useless radios. This thing has power and range. I use it for hunting and it is great. I bought a bunch of cool accessories also. Works very well and the battery lasts for at least 2 days of use.
This was my first radio and I am very pleased with the features. It seems to be very solidly built and I am looking forward to many years of use. I suppose this is true oif any radio but a bit more power would be nice. Overall an excellent value.
As an operating Amateur Radio, the sound quality has been very good into the local Repeater, even on Low Power. I have not taken the opportunity to check Simplex Operation, so I cannot comment on that. For the price of this unit, I would say it is a good bargain, but expect some initial confusion when trying to program into Memory Channels.
You can use a software program but that can also be quirky (free program called CHIRP)- User manual is useless- Scans only 3 channels per second making it very slow- The included earpiece is does not work well- 4 watts of power as opposed to 5 watts- The radio does not automatically know the offset so you end up having to enter both transmit and receive frequencies.
Not long after getting the radio in the mail, the power went out in our area for over 14hrs. This was the only radio i had that was available. I had not set up the ham frequencies but could get a solid FM signal that played music and updated us to the situation over the night. Not too bad. Cant wait to try it on communications. Nice little radio that made itself a home instantly that night. Tony
It works flawlessly and the reception is excellent. I can't comment on the transmission power of this radio, as I do not transmit on it.My only problem with the radio (and this did not directly apply to me as I had prepared for it) is the lack of both a user friendly interface and a coherent manual. An easy solution to this would be to buy the USB programming cable and program the radio using your computer and the free software known as CHIRP.
It uses a proprietary battery that has to be charged from the wall - or some sort of separate DC adapter I suppose. You will want your primary emergency weather radio to have spare/replaceable batteries (like AA/C/D) as the power could be out for weeks. But it is nice to know you can reach the outside world in the event of roof collapse or flooding or some other catastrophic event that occurs in extreme weather.
Answer: Up to 4W on high, however it depends on the band and frequency.
