Many thanks to SWLing Post contributor, Phil Brennan, who writes:
[Recently] one of your contributors mentioned that he purchased a BHI DSP unit at a discounted price. I purchased one (a different model to the one in the previous post) some months ago before I headed away travelling.
The post reminded me that I had made a small video demonstrating the DSP unit on my FRG7. The video shows me tuning the DSP on a broadcast of Voice of the People on 3912 khz. While QRM at my place isn’t too bad, it’s still present and the DSP does aid in clearing up a signal.

Voice of the People is usually jammed by the DPRK and the DSP also assists in reducing the roar of the jammer. Of course one can go to far with DSP and the audio can suffer from that underwater sound.
Thank you, Phil! The FRG-7 is an ideal receiver for something like the BHI module since it precedes on-board DSP. The great thing about an in-line module, of course, is that it can be used with a variety of receivers.
Very good demonstration! (It helps I love the FRG-7!!) On my wishlist of products to buy – maybe a Christmas present to myself?! Thanks for posting this!
Hi Robert. There are cheaper models but I think my purchase was worth it. I have pulled quite a few signals out of the mud with the DSP. I enjoy your website by the way. Thanks.
I miss my FROG. 🙁 Bought mine from Gilfer many years ago after saving up my allowance. Lost it in a fire and wish I had one again.
Nice demo. That really cleared up the audio pretty well.
Hi John, yes I’ve been impressed with DSP unit’s performance on my DSP equipped receivers such as the IC R75 and to the CommRadio CR1. I think yhe unit iscs good investment indeed.
Hi Rob, i always wanted a frog when I was a teenager in the 70s but they were about $450 in Australia in 1977 which was a lot more than I could ever dream of affording. I lost contact with the hobby until I was 50 but a chance view of the frog on ebay once again sparked my interest. And I could afford it at last! I haven’t looked back and now have more modern radios which arguably perform better. But my beloved frog is still a favourite.
Thanks for the video!
I have an SDR, the Winradio G33DDC that has great DSP on it but I still use this module, as it does a trmendious job at my QTH for cleaning up audio issues, especially in the Tropical Band frequencies where I tend to listen most. Great unit indeed. I’m personally surprised more SWDXers don’t use this as we’re always looking for ways to get a better audio experience.
