An excellent addition to any receiver....

Time owned: more than 12 months

I have installed Inrad products in many of my radios (full bank in the K3, R5000 receiver, FT-817, etc) and have always had excellent results. The support from the staff of Inrad has always been great - very helpful and willing to go the extra mile.

Big Difference w/filter
|
Time owned: 0 to 3 months
|
I just installed the INRAD #92 filter in my TS-2000. What a difference it made. I initially set up my signal generator and took signal measurements in the IF to see how it performed.
After installing the filter, I only noticed a 1 dBm difference in level which is OK. The big thing I noticed with an antenna attached is that the background wide-band noise level was reduced substantially. It makes for pleasurable copy of CW and SSB signals with the TS-2000.
I highly recommend it!

#720 2000 Hz for FT-897D
|
Time owned: 3 to 6 months
|
Hello
I spent 6 months researching and found the reports on the Yaesu 2300 filter, most said no difference between the stock. A reports on the INRAD #720 are BANG ON. I live in an apartment in Toronto, constant 9+ db of noise and this helps cut out some of the junk allowing me to work weaker stations.

It works and it works well

I operate mainly mobile and installed the 2 KHz Filter in my Yaesu FT857D. It works mighty fine on both TX and RX once the menus are setup where you want them and on the air Radio check always helps to, This was well worth the $$$.
I'm very satisfied with this filter.
Buy one!

Inrad good addition

I added a 2.3 Khz filter to my FT-897D. I did not know what to expect, but I am very pleased with the results. Even though the Yaesu crystal filter and DSP have the same bandwidth, the sharp skirts of the Inrad make the audio "pop" and make signals much more readable.

Nice improvement
|

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

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.
