Great Service
|
Time owned: 0 to 3 months

I can only put 1 filter in my IC-718. I wasn't sure whether to use the 1.8Khz, or 2.1Khz SSB filter. When I spoke to Inrad, they said that I could order the 1.8Khz and if it was too tight for me, change it out for the 2.1Khz.
They also charged my card when the Item was out of stock and they were awaiting delivery. This is not something they normally do, but the £/$ exchange rate was great at the time I placed the order - so when I asked if they would do it, they obliged.
Great Product, Great People, Great Service.

I took advantage of INRAD's New Year's Day offer, and ordered a 400Hz filter for my TS-570SG. The filter arrived sooner than expected, and works very well. The service from George and Georgia is exceptional. Highly recommended!

Great filters, great company

I've used these filters in Yaesu, Kenwood, and Ten-Tec radios, and I have always been very pleased. Last week I purchased a 500 Hz CW filter for my new FT-857 for $125 instead of the Yaesu filter for $160. As always, the INRAD is great, and this time a lot less expensive. See also my FT-857 review:

I just installed the 400 Hz CW filter into my Icom IC718 and I am very pleased with it. Sounds much better than the Icom FL100 in my 706 and cheaper to boot!

Inrad filters make a good radio better
|
Time owned: more than 12 months

I first ordered a 2.1k crystal filter for my FT-847 on rx and thought the sound was a little narrow for my usage as a ragchewer. I then exchanged it with them for the 2.8k and BOY does this baby ROCK. Smooth sounding is the best way to describe it. Very nice people and great service. I then got the 2.8k for tx as well and have been getting great audio reports. It really make this radio shine and was the best upgrade for this radio for HF.

Special needs not sloughed off

I am refurbishing a Yaesu FT-80C (which is like an FT-747GX with a metal case, but lacking certain features). One feature it lacked was a CW filter. I tried their 701 filter and it worked quite well. They were very polite and understood about the experimental nature of what I was doing. Very nice people.

The best filters you can get!
|
Time owned: more than 12 months

I have several IF-filters from Inrad in my FT-1000MP Mark V and the review is short and simple: "these filters are the best you can get!"
The shape factor of Inrad filters is excellent; most of them have a shape factor of 1.5, 1.6 or 1.7.
The sound of these filters is very good.
The technical service from George and the very kind and fast delivery from Georgia are excellent too.
In short: "Inrad is equivalent to excellent!"
Don't look any further; just choose Inrad. Enjoy yourself with these filters for many many years. You will not be disappointed in any way.

Great Icom Alternative!!
|
Time owned: 0 to 3 months

I recently installed an INRAD #314 filter in my Icom rig. This filter is a 2.1-KHz bandwidth I-F stage crystal filter, with a shape factor of about 1.52:1 from -6 to -60 dB, according to their posted performance chart.
I chose this filter in place of the Icom FL-222, its nearest equivalent. I did this for two reasons: 1) I am not comfortable with the FL-222's 1.8-KHz passband. This is a bit "too" narrow for most of my SSB work, resulting in a "nasal" quality to the audio. 2) PRICE!
At $160.00 shipped (two-day arrival time!), it is nicely cheaper than the FL-222.
Having used Icom filters in three previous Icom rigs, I wanted a better option than the filters they offer for narrow SSB use. I am not disappointed with my choice of the INRAD! This filter meets my needs nearly to perfection! The audio passband is very well-chosen, allowing good intelligibility with the received signal.
Gone is the annoying "choked" sound that accompanies filtering of less than 2 KHz, yet the improvement in rejection over the stock 2.4-KHz filter in my rig is significant! The quality of construction and mechanical "fit" is excellent, too.
I am not implying that Icom's filters are of any lesser quality---they are excellent, at least in my experience---but the choice of available bandwidths in the Icom line-up leaves something to be desired in narrow-passband SSB filters.
The INRAD people have addressed this shortcoming in a VERY satisfactory way! Top-notch service, too! Highly recommended!

I recently replaced my stock Kenwood cascaded 270 Hz and 250 Hz filters with cascaded INRAD 250/125 Hz filters in my TS-850S. Am very pleased with the improved S/N ratio and selectivity with no ringing whatsoever. The 250 Hz filter for the 8.83MHz IF installed okay next to the Kenwood 1.8 KHz filter. I find that I don't really need my outboard MFJ DSP unit on CW, except for the additional audio output power it provides.
