Gap Hearit Speaker

Hi to the group,

I have a high noise level, besides living in an antenna restricted home. I usually run S5-8 noise on my K3 with the filters adjusted best I can, and bandpass >300-500 Hz. Someone has recommended the Gap Hearit Speaker to me as being so wonderful. I have been checking into it, and it appears as just another DSP and speaker ckt. So, I’m wondering if it would really make any difference to me, with the K3 and it’s internal DSP.

I work mostly CW and due to my indoor antenna, with weak signals. I also use phones mostly, but, I see you can plug them into this unit, so it shouldn’t make any difference phones or speaker, right?

Anyone have any experience with this product and can offer any advice, I’d appreciate it very much.

Tnx & 73

Bill, k6mgo

Re: Gap Hearit Speaker

The GAP Hear-it is quite effective on SSB, but not on CW. I don't use their speaker, but do have the Hear-it module.

Th narrower the bandpass, the less effective DSP noise reduction becomes. For CW at narrow bandwidths, you might be better off using the audio passband filter (APF) in the K3.

I've used just about every DSP speaker available in my mobile, except
this one. That said, the Gap speaker uses the BHI DSP module, which I
played with at Dayton and it was quite good compared to other options.
The two best AF DSP modules I've seen are the West Mountain Radio
Clearspeech and the GAP/BHI. BTW, I hated the SGC DSP speaker. I
currently have the Clearspeech in my mobile with an Icom 7000. I find
that the combination of a little IF DSP (used in the Icom 7000) used
in conjunction with some AF DSP makes for a very powerful NR
combination.

Keep in mind that NR intelligibility is fairly subjective to an
individual ear, so what I find helpful, another person may not like. I
have considered trying a similar combination on my K3 in my noisy home
environment, but haven't gone down that road yet. I may still do that
unless we get word from Elecraft that a vast NR improvement firmware
update is coming soon.

If you have a high noise level, you might try the Pixel Loop (38 inches).

http://www.pixelsatradio.com/product/shortwave-magnetic-loop-antenna/

This is very effective at reducing noise and interfaces well to the K3 thru the RX ant.

I have two mobile setups with IC-7000 radios. One has the GAP and the
other the West Mountain. These speakers DSP is primarily in the audio
range and helps with hiss and allows less radio DSP to be used.

In a mobile environment where you need an amplified speaker these are
both good choices.

What they do not do is fix high background noise, if the signal is
below the noise these speakers will not allow you to hear it.

Now having both I believe the the West Mountain is slighty better than
the GAP as it appears to have a better speaker in it.
