The old is new  Time owned: more than 12 months
I have owned and used this unit for about 15 to 20 years. It is really useful for rigs that do not come with a built in RF speech processor. Even some of the earlier rigs that only came with audio processing, such as the Kenwood TS-120's and TS-130's. Let me tell you on the air with the RF-440 properly operated and it is hard to tell that your not running a $$$$$$ rig. I keep mine for use with my backup TS-130S. Makes a great setup. I see that Ten-Tec is now producing a similar unit so I have to guess there is a demand that Daiwa is not filling. If you find one and have an older rig, you don't have to spend $$$$$ for all the outboard add on's that are now being pushed to make the expensive rigs sound like AM. I agree the instructions are a bit flaky but it is simple to set up on the air.

Great RF Speech Clipper - Buy it.  Time owned: 3 to 6 months
Hard to find, but worth it. I'm using with a KWM2A, which of course doesn't have any processor. I set up according to the (poorly written) instructions, and spent quite a bit of time on the air testing various settings. What I found is that if operated per instructions, absolutely no deteriation in quality of audio (spec is less than 3% distortion for 20db clipping!). And average output is much higher. Did what it was supposed to do. Highly recommended.
