[Milsurplus] ARR 15, how to narrow selectivity???

[wf2u at ws19ops.com]

I use one of several switched capacitor type audio filters I have,  
like the Autek and SCAF with very good results on the ARC-2, and no  
internal mod is required, just plug it in to the audio output. I  
manage to use mine in crowded band conditions on 80 M with the filter.
I haven't had my ARR-15 powered up yet, but I'll use the same method  
when I do.
I used the audio filter with the Wireless Set 19 as well and it makes  
the difference between hearing a particular station and hearing the  
whole band at the same time...
