Nice improvement Time Owned: 0 to 3 months.
I just installed the 500 Hz filter from INRAD in my FT 101ZD. CW is now much better now that the adjacent noise and close stations are eliminated. I use the ZD on 40 M CW with a J44 straight key, and the filter makes a huge difference.

FANTASTIC Time Owned: 0 to 3 months.
I just installed a pair of Inrad 400 hz IF filters in my Kenwood TS-830S. The 8.8Mhz filter took a bit of effort and the 455Khz fit perfectly. The performance is outstanding. The TS-830S with these filters gives my Orion II and Flex 5000A some competition. I am 100% pleased.

Collins S-Line AM Filter Time Owned: 0 to 3 months.
My impression of the 707S AM Filter for the Collins 75S-3B/C Receiver.

The filter works very well and even has a clean flat passband.

Complaint:
The PCB used to mount the filter is to wide! For those receivers that have the Mu-Metal filter covers installed it is impossible to place the cover back with the filter installed. This required me to trim off a little bit of the side of the PCB and also round off the corners. After doing that I was barely able to get the cover on. If INRAD would have made a PCB exclusively for the Collins 75S3B/C series that had a PCB no wider than the mounted Collins filter it would have been an easy install.

So I can only rate this a "4". Performance wise it's a "5", but installation issues brings it down one notch.

Great quality added ! Time Owned: more than 12 months.
I have with 4 transceivers good experience with these kind of filters.
I installed for the first time SSB Inrad-IF filters in a FT1000D and the audio-quality was significant improved.The 2,1 Kc Inrad-filters working better then original 2,4 Kc IF-filters.
The Icom rigs IC781 & IC775DSP had also their SSB-upgrades to Inrad,complete with roofingfilter like the FT1000D and i enjoyed the improvement much..
The 2nd FT1000D (year Y2K) have since a week the IF-filters installed for SSB and CW and sounds great again and is now 100% Inrad (sub-rx included)
Costumerservice/aftersales is very good,one IF-filter looked a little damaged and Trey sended a new one.That's great service.
If you have simple or difficult qeustions..e-mail response from Trey is fast and good.
Inrads are not cheap but you get a lot of joy back.
Highly recommended.

I installed 2 years ago in my Yeasu FT1000D 4 SSB IF-filters to replace the original.
The 2.0 section was sounding better then the original 2,4 Kc IF-filters from Yeasu,says enough i think.....
Since 2 weeks i have SSB-inrads in my Icom IC775DSP which are working just great !

Great product - good service Time Owned: 0 to 3 months.
With the new breed of DSP radios I didn't think I would have to buy another filter but I recently bought an FT-857D for portable RTTY work and I'm planning a trip with it to VK so needed a good 300hz filter. Its was cheaper to buy this from the US than the stock filter from UK suppliers! Delivery was very fast and it was very well packaged. Fitting was very simple (Far easier than the old days where you have to solder them and move jumper wires). Performance is excellent and theres very little insertion loss. If I ever sell the FT-857D I will move the filter to the 2nd receiver in my FT-2000

Great Service Time Owned: 0 to 3 months.
I had orderd a new SSB filter for my FT-1000MP MKV and after install there were problems. After troubleshooting, the new filter looked to be the problem. An email and an explanation to Trey at INRAD brought a quick response and a new filter was on the way.The replacement fixed the problem. Thanks Trey! quality product with service to match.

250 Hz CW Filter in IC-703 Time Owned: 0 to 3 months.
I just installed INRAD's 250 Hz CW Filter in my IC-703. It's awesome, cutting the QRM and noise tremendously. I recommend it without reservation

Spend the Money It's Worth it!!! Time Owned: 6 to 12 months.
I have had the Inrad 8.83 khZ filter in my Kenwood TS-850S for about 9 months now. I love it. I ordered the 2.1 455 khZ filter last Friday it came this Friday (12/21) I installed it as soon as I got home WOW what a better combo than before. I can get 3 khZ from a BC station with out a scratch or squeak from it and can copy a s2 signal. The best I have ever had with this radio. You will not be dissapointed with these filters no matter what transciver you own.
