Description: This is the similar amplified module they sell in other forms, but installed in a small module designed to be placed in-line with your speaker output. It is essentially portable, though requires power to run. Convenient to swap in and out of the shack and your mobile.

After a month of use
|
Time owned: 0 to 3 months

I upgraded this to a 5. I did this because as funky as the 1-8 level control is, I never use it. I set it at 5, which works for me. I suppose I could clean up my desk a little by mounting it inside my speaker, but I may want to change my speaker someday. You have this option because the connectors and switches are not mounted on the pcb. This device should be left powered up. Otherwise, you need to turn it on each time you turn on your rig.
Again, this adaptive noise reduction is a must have if you have $200 you can spend on an accessory.

Excellent addition to any Xcvr/Rcvr
|
Time owned: 0 to 3 months

I read the review of the ANEM in QST and also email its author, as well as researched internet posting about it. I have a FT1000MP Mark V. I have the roofing filter as well as the 2.1 KHz filters as well, and can pretty much close QRM out but that nasty hiss remains (unless the sig is >S7 and I can use the IPO; can't add both the roofing filters and INRAD hiss modification).
The ANEM takes the hiss out and improves the receive quality I can get! Its an external AF DSP which is simple: off/bypass/on; and DSP level setting (1-4 or 1-8). The radio S-meter may be a S6 with noise, but the speaker sounds like S1, and I can easily hear the S-5 voice. There is little affect on the voice quality, only the noise. I have not used in on CW, only HF SSB. This is much better that the NR capability in the Mark V.
The price is about $200. While its advertised from Gap, most dealers (AES, R&L, HRO, etc) have no idea what the product is. I could not reach Gap, found that W4RT had it advertsied and got mine from there. Excellent service, Barry emailed me with availability and pricing at 10PM Wednesday night, I ordered it Thursday and was using it Friday. I highly recommend W4RT---they made sure they had one while on the phone with me and opened the box to make sure it was all there---WOW! The units are hard to find right now in the US. Way to go W4RT Electronics!
I think that the ANEM would be a valuable addition to any Xcvr which does not have a good internal IF DSP and think its AF DSP is probaly better than other older DSP (internal or external) implementations. The only down side I found is that when switching functions which greatly affect the audio, the ANEM must recalibrate itself and so you'll get the hiss back for about a second before the ANEM takes over (when going out of Xmit back to rcv, or switching a rcv function like NB, EDSP, etc).
I chose to get this speakerless unit rather than than those with speakers so I could decide the size what I wanted it on. I am using two simple car speakers (unamplified) which look nice with the Mark V. (I have used the SP-8 and the ANEM would improve its perforamnce greatly).

Adaptive AF DSP...amazing
|
Time owned: 0 to 3 months

I first met one of these adaptive AF DSP modules in the version designed to be built into a radio. A friend had it and as soon as I got a demo of it, I knew I had to have one.
A lot of demo links for products are exaggerated or done under ideal conditions. This link here I can tell you is exactly what you can expect. Just play the sample .wav files. They speak for themselves.

I don't work anything but voice modes at this time so I can't give feedback beyond that. However for ragchew or nets, this thing is just ideal. It knocks the background hash down so that it is listenable for hours.
I have an older Kenwood TS-680S which has pretty much nothing for noise reduction or filtering so this is an invaluable add-on to this era of rig.
I should also mention that there are 8 levels of noise reduction, so finding the right balance is easy. You cycle through the levels, in half a second or so it samples the signal and 'settles' in. Fantastic.
