| Reviews Summary for Idiom Press SCAF-1 |
|
Reviews: 78
|
Average rating: 4.8/5
|
MSRP: $89.95
|

Description: The new SCAF-1 filter from Idiom Press makes your radio listener friendly, whether you are an SSB or CW operator. Using a modern but little known technology called SCAF filtering, the SCAF-1 is an active audio low pass filter offering user control of the filter cut-off frequency, yielding a stunning 96dB per octave roll-off of signals above the cut off frequency, and no white noise. It is the perfect partner for your crystal or mechanical filters. And, unlike most audio filters, there is absolutely NO ringing.

Fun 2 night project

Concise and accurate instructions, top quality components, and above average circuit board. Amazingly, this unit also solved an issue that has plagued my Icom 756-Pro-III for years by eliminating the CW artifacts in receive mode (see Elmer forum http://www.eham.net/forums/Elmers/195991).

2nd one, like a fool sold the first. Straight forward kit. Love it for CW, helps on phone too. Real time, just dial in what sounds best. Worth hanging on to.

Every mobile should have one

Time owned: 6 to 12 months

No matter which mobile transceiver you use, even ones with IF based DSPs, there are times when the SCAF makes copying that rare one worth the effort in building and installing one.
I take indifference to one item in the description about ringing. if you're driving a speaker with the unit, it is possible to overdrive the input stage, which will distort the audio and give you the same effect, albeit rare.

great product and service

Hello:
Several days ago, I posted a question concerning the FT2000 sub receiver, and its loud white noise hiss, to the yaesu reflectors. I was looking for possible solutions to remove this hiss from the audio.
It was recommended that I try an Idiom Press Model SCAF-1 audio filter.
I decided to try one.
It arrived today, and is now in service. I can say that this product does exactly what it says as advertised. The white noise is gone.. and I can now use both the main and sub receiver without the irritation of this white noise.
I recommend this product to any one else having the same issue.

Worth every penny!

Based on partly on the eHam reviews of the SCAF-1 and my experience with Idiom Press's K-3 keyer (I love it!) I purchased the SCAF-1 kit.
The kit instructions were clear and it went together in a few hours. I inserted it between my Drake TR-7 and the speaker. What a difference! I was easily able to copy virtually any CW signal that I selected in the middle of a pile-up.
There's some sample audio of the Idion Press web site. If you have any doubts give it a listen.

Update
|
Time owned: more than 12 months

I just wanted other folks to realize what an excellent tool this is. I have lots of HF radios with factory 'upgrade' SSB and CW filters and some INRADS, also. This little filter is FANTASTIC, and you can switch it between radios!
Just tonight, I had one of my receivers tuned to the CW portion of 40 M.
(I don't know about your QTH, but here in N. Florida, the bands take a HUGE dive at night, come-on Sol!!)
Anyway, the receiver that usually receives 'background' Ham sounds varies, but this week, my Allied AX-190 was in the queue.
(Don't laugh! This is a nice, sensitive radio. I have gone through it and it works VERY well. I have an SX-190 also).
Since these radios were never made for serious CW reception, the filters being too narrow for AM and too wide for CW, I noticed the SCAF-1 sitting on the nearby FRG-7.
The FRG-7 does have some extra Kiwa filters in it. The SCAF-1 still made a great improvement.
However, when connected to the AX-190, the results were just short of unbelieavable.
Signals that were passing through the AX's 'barndoor IF', became single signals. Usually, just a slight touch on the radio's VFO brought the CW tone just where I like it. Switching off the SCAF-1, returned the other signals AND hiss, etc. Night and day difference!!
No, it ain't gonna turn your $20 special into a FLEX5000, but it will make those boatanchors MUCH more enjoyable!
Is this not what it's ALL about?
Now, if it would just mute 14.275. ha ha

I can only say that if you have a bunch of er, 'inexpensive' receivers like I do, this little filter will just flat amaze you....

Great product and great people!!

Is there another stand alone unit like this???
This thing makes my "Boat Anchor" more fun! Not to mention, the well-used "Pre-owned" rig that has occupies my station.
This thing would have been great back when I was using that Collins and EAC gear in anger!!! :- ]

Well, now.

Well, now this is a great addition to many stations. I have had one for years and used it with many rigs ... older ones (Omni C, Corsair II, Drake TR-7, etc.) newer ones (Orion, Omni VII). I have also used other outboard DSP units (by MFJ, RadioShack and Timewave). This SCAF-1 Audio Filter has its place and is an inexpensive way to improve the audio output of many rigs. I mostly operate CW.

Great working filter!
|
Time owned: 6 to 12 months

Read the reviews on this filter and thought I would try it on my Kenwood TS-2000. Am I glad I did! The 2000 does pretty good on it's own but when you put this in line the receive increases dramatically.
Now I'm able to put out very weak signals and hear them very well. Does a great good job rolling off interference several kHz away and completely does away with static crashes.
If you have a high end radio you will most likely not need one. But for me it works great with my TS-2000. Will remain in my shack for a long time to come.

Best audio filter there is!
|
Time owned: 3 to 6 months

Got my SCAF-1 a few months back and been testing it on lots of different rigs. On my 950SDX it isnt such a big deal but using it on say the TS870 or 850/DSP100, Astro 103BX - wow! I've had all audio filters there is, from the Datongs back in the 80'es to Timewave, the NIR's and really nothing beats the SCAF-1.
So if you want a truly good filter, go for it. This filter is so good and easy to use so it should really be built-into the rigs by default...
