[ICOM] Headphone pre-amp

Perhaps you can find a small stero amp 
that would give maybe 10 or more dB 
gain and combine with stereo a headset 
so that you could adjust to get a close 
overall balance to equalize between your 
ears.  Either separate volume controls 
for each channel or simply a balance 
control would do the job. 
 
I am not sure what RF pre-amps would 
gain for you. 
 
Good luck!

I have a PRO 3 and thoroughly enjoying it it. I am hard of hearing 
in one ear However when some sigs are in the noise and I can 
barely hear them,  I would like to turn the af higher, but it's 
already at the max. I have additional rf pre-amps besides the 
internal ones. I realize that the s/n won't change, but that's okay 
since I'll be able to copy it. 
 
Anyone have any thoughts? 
 
Thanks
