So easy to install, a General can do it....
|
Time owned: 0 to 3 months
|
I recently purchased a used FT-1000D to back up my FT-2000 here. I purchased an INRAD roofing filter mod for the unit, and also ordered one for a local new ham at the same time to upgrade his as well.
The instructions were so clear, and the design so well carried out that both went in without a hitch, and make for a very clean install. We soldered them in at the same time, sitting side by side on a workbench.
Great quality, Great instructions.
How well does it work? Only QRM will tell!

TS-850 Roofing Filter GREAT
|
Time owned: 3 to 6 months
|
|
I bought the TS-850 when they first came out. Once installed I did a double take WOW I can now get 3KHz from a S9++ and not even get a scratch. It turned my 850 into the best transciver I have ever used. I will put it up to a K3 anytime having used both. If you have a TS-850 this is a MUST it turns the 850 into a WORLD CLASS++ Transciver.

Inrad for Omni VI+
|
Time owned: 0 to 3 months
|
I have to agree with other reviewers, it makes a great radio even better. I took the idea from another reviewer and connected the filter on/off to the attn switch for maximum flexibility. Simple installation.
Good advice and fast shipping from Inrad. I'm a happy filter user.
73,

Great Roofing Filter for OMNI VI+
|
Time owned: 0 to 3 months
|
SSB Roofing filter kit for the Ten-Tec OMNI VI+. Makes a great radio fantastic. Have a neighbor ham with an amplifier that is only 8 blocks away. With the roofing filter and the PBT, i don't even know he's on the air!
Install was easy and i used the attenuator button to switch the filter in or out.

Update on Inrad 600 Hz Roofing filter for Ten Tec Omni 6 Plus
|
Time owned: 0 to 3 months
|
In a previous review, I outlined my experience with the Inrad 600 Hz roofing filter for the Ten Tec Omni 6 Plus. Immediately after the filter installation, I observed that in the N1 or 500 Hz first IF filter position there was a notable reduction in atmospheric noise and somewhat better close in strong signal performance. However, the insertion loss in the N2 or 250 Hz first IF filter position was so great as to make that selection not workable. My problems arose because the filter board is mounted on two nylon standoffs centered on each end of the board which allows the board to wobble back and forth. The 12 VDC power connectors are mounted on the front edge of the filter board, with the soldered contacts exposed on the bottom. Apparently, when dressing the new wires added for the filter I depressed the front edge of the filter board enough that the power connectors underside shorted on the metal shield the filter board in mounted on. That resulted in a number of parts losing their smoke (very little smoke as I never saw it). That whole incident was my fault. However, I'd strongly recommend a mod to mount the board with four standoffs, one in each corner.
The SWR problems on 160M were unrelated to the Inrad roofing filter. By the way, the Ten Tec technician I spoke to said he had seen more than five Omni 6's with the Inrad roofing filter mod that had absolutely NO problems.

Like a new 775dsp
|
Time owned: 0 to 3 months
|
I have a fully loaded IC-775dsp. I decided to install the Inrad roofing filter for this radio. The installation for the 775dsp is more difficult than for some of the other transceivers, so I decided to have Beltronics in Hollis NH do it. It was money well spent.
When I got the radio back, I thought the RF gain control was turned down. It is a much, much quieter radio. But when you have a station in the roofing filter passband, you can see that it is full strength on the S-meter. I know this because I have done some tests with local stations whose ground wave signal strength is quite steady and predictable here.
The Inrad roofing filter has made a great radio an even greater radio. The only downside, which is relatively inconsequential, is that you cannot switch it out of the circuit (but you really don't want to after you have experienced it) and, it may make some of the "hi-fi" AM stations sound a little muffled. But heck, if I want to listen to Hi-Fi AM, I use my R-390 with the IF filter in the 16khz position.
Definitely recommended for those who want to improve selectivity.

Shines up an old TS-930S
|
Time owned: 0 to 3 months
|
I installed the Inrad roofing filter in my "new" 1982 model TS-930S, which is destined to be the second rig in my SO2R contest station. Listening on 10m while transmitting on 20m, I can get within 2 KHz of the second harmonic of my 14MHz signal before the S meter even moves. In comparison, my "primary" rig is a TS-850S with the manufacturer's 500 Hz (455 kHz IF) filter. With the TS-850S, even with AIP on, I get an S1 signal about 20 KHz either side of the second harmonic. IMHO, the Inrad roofing filter (and the PIEXX motherboard, but that's another story) makes the old '930 more than the equal of most rigs out there for CW contesting.

Great filter
|
Time owned: more than 12 months

I have installed the roofing filter in my ft 1000d.
It made a huge difference with loud stations a few khz away. George is the greatest person to deal with,he goes out of the way to make sure you are happy other company's could learn from him.

Pretty good filter
|
Time owned: 0 to 3 months

This review is for #701-A and the actual rating is more like 4.5. I got the #701-A (400Hz) for my FT-920. This filter is actually better than the OEM CW filter. It has very steep rolloff. The bandwidth is actaually 470 Hz at 6db, not the 400 Hz Inrad claims. I dont mind to have the filter a bit wider (the OEM filter is 500 Hz), but they should advertise the filter as 500 Hz not 400Hz. The filter has good attenuation in the stop band and does the job fine. I am happy with the performance! The reason for 4.5 score is because it is out of specs - 470 Hz vs the 400 Hz claimed on their site (I can accept few percent deviation from the specs but here we are talking about almost 20% difference. Another issue is the quality of the adapter boad. The filter comes installed on a small adapter board - the board has no solder mask, the plating of the tracks has tarnished, I had to remove alot of flux from the board and re-do some of the soldering before installing the filter. There are 2 caps and two jumper wires besides the actual filter and i've seen better soldering jobs. The tabs of the metal filter case were not soldered at all to their corresponding pads on the PCB. As i said the flux from the soldering was all over the board - it almost looked like somebody was learning how to solder on this adapter board (or maybe the filter was made towards the end of the work day :-). They used excessive amount of solder and yet one of the jumper wires had to be completly redone.
I just didnt expect to do all this to a factory made filter.
As i mentioned before, the performance is very good, better than I expected and better than the original Yaesu filter and I recommend it! I might even install the inrad filter switching board in my radio.
