From stationary multi-feature communications equipment to portable devices, we have led the ham radio market for nearly half a century. Communicating through radio waves with people all over the world is what ham radio is all about and what keeps many people hooked. Finding that distant but recognizable signal buried in a sea of noise is the type of enjoyment of discovery unattainable from sending an instant e-mail overseas through the Internet.

We also subsequently developed independently the ultra narrow IF crystal filter, a breakthrough that paved the way to commercialization of SSB communications. These breakthroughs in basic research not only demonstrated our technological prowess to the world, but was also instrumental in diffusing the concept of SSB communications in the HF band, the current standard, throughout the world. The YAESU brand has consistently represented the best in communications equipment to the world's Top DX'ers for almost half a century.

Operation is subject to the following two conditions; (1) this device may not cause harmful interference, and (2) this device must accept any interference including interference that may cause undesired operation. From stationary multi-feature communications equipment to portable devices, we have led the ham radio market for nearly half a century. Communicating through radio waves with people all over the world is what ham radio is all about and what keeps many people hooked. Finding that distant but recognizable signal buried in a sea of noise is the type of enjoyment of discovery unattainable from sending an instant e-mail overseas through the Internet. We also subsequently developed independently the ultra narrow IF crystal filter, a breakthrough that paved the way to commercialization of SSB communications. These breakthroughs in basic research not only demonstrated our technological prowess to the world, but was also instrumental in diffusing the concept of SSB communications in the HF band, the current standard, throughout the world.

It quickly cools the room on hot days and quiet operation keeps you cool without keeping you awake. Low power start-up and operation conserves energy and saves you money. Ready-select electronic controls allow you to set the comfort level to your preference, while a convenient temperature-readout displays the set temperature. Effortless temperature sensing remote control allows you to see, set and maintain room temperature from across the room. The multi-speed fan features three different speeds for cooling flexibility and the 8-way comfort control design allows you to easily control the direction of the cool air, wherever the unit is mounted. Plus, the clean air Ionizer removes pollen and impurities from the air providing relief for allergy sufferers.To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness. Please try again later. OuterLimits 5.0 out of 5 stars I have 2 that are over 5 years old still running cold. I got this one to take the place of a 6,000 and 8,000 BTU that I used in conjunction to cool the kitchen and living room in my total 912 sq ft house. By the math I should be using at least a 15,000 BTU unit for those two rooms. I am very happy that the 12,000 alone keeps the entire house comfortable even on 90 degree days. I also use a 6,000 BTU in the bedroom when needed. One of the features I really like is the remote temperature sensing remote as I put it in an area away from the unit which helps to even out the temperature in the entire space. I have seen reviews where people say the unit is loud. Yes it can be when the fan is on high but lets be real here there is a fan blowing cold air at a high CFM and the decibel specs are online do your research. I find the noise level quite acceptable. This is the third one that I have gotten from Amazon.

Frigidaire shame on you and Electrolux who actually is the owner of Frigidaire.The box was undamaged both outside and inside,in other words no damage to the extremely small amount of styrofoam on only the top and bottom of the unit. The back fins were damaged and the corner of the unit included is part of the framing on both the back and side of the unit. Since there was no damage I can only guess that the unit had been dropped prior to packing. I bought two units and both had damaged back fins. I definitely will never purchase any large item such as this thru a web site such as this. The unit functions luckily but is unsightly with the damage.We purchased it to replace a smaller BTU unit and from the moment we turned it on we knew it would be exactly what we needed. Husband said installation was fine. The auto function works great, keeping a more constant temperature and actually turning off when it's not needed. So glad we got it installed before this latest heat wave as now we can sleep in a wonderfully cool room. Thinking of replacing our older unit in the living room with another just like this one.Having four way vent control is super handy as is the remote temp sensor in the remote control. Also love that you can change the air flow through the unit (recirculation, mix, and vent) would definitely recommend this unit.The price is right too.In order to navigate out of this carousel please use your heading shortcut key to navigate to the next or previous heading.

It came in slightly damaged on the outside casing, it may have been dropped on a corner of the box. The damage is external, did not affect the functionality and not enough to bother sending back. I will fix it as best I can when I take the unit apart for fall cleaning before I store it for the winter. It really is annoying when reviews mark down the stars due to damage by a shipper or blame Amazon. Come on people that really has nothing at all to do with the product itself and is an unfair review.I had to have a professional come and install this thing in my window. I thought I could I stall since I can make furniture and all sorts of things. But, after 12 or more attempts I gave in and cried like a baby that this window air conditioner had beaten me. I started looking for professionals and looked and looked and looked for about a week. I had started the return process on this piece of whatever when I got a return phone call and I thought the heavens had opened up on me. I was dead wrong. So we finally get it in after 3 hours of trying different things here and there. I want to say again this man is a real professional. This Frigidaire window air conditioner is screwed in and caulked and foam to prevent air leakage. This thing won’t turn on. The remote can’t turn it on. The “things to try before calling us” don’t work. I called the 1(800) number and they rattled of another number and I called them and got no one.This unit failed to cool right out of the box. Called Frigidaire and they gave me the procedure to file a claim. I following the procedure exactly the following day. Now 4 days later they tell me they are going to buy back the unit by sending me a prepaid Visa card in 3 weeks minus the sales tax I paid which was almost 30.00. And 3 weeks with temperatures in the mid 80's and 90's will be a long 3 weeks. I just received the second unit that I ordered a couple of days late. I think I should probably just return it before I even open the box.
