[Elecraft] SO2R thoughts

Hi Tom,

Yes, there certainly is a conflict of interest involved when expensive 
devices are sold by the prescribing physician. Same deal with 
eyeglasses. :)  On the other hand, human senses are logarithmic in their 
response, and our brains compensate a lot for any deficiencies. For that 
reason, we get accustomed to loss of high end, which is quite common for 
people our age, and made worse by noise exposures like yours. My XYL and 
I both have significant hearing loss, mine a bit less than hers, and 
we're considering hearing aids. BTW -- when you get to that, W6OAT is on 
his second hearing aid, and he loves the new one he got from Costco.

Yes, you can use RXEQ to compensate for at least some of your hearing 
loss. My friend K6DGW has rather severe hearing loss, and at my 
suggestion, he's done exactly that. What you would do is set all of the 
lower bands for maximum cut, and boost the higher bands. As a starting 
point, set the four lowest bands to maximum cut (-18 dB), set the fifth 
band to cut about 9 dB, set the highest band for  about +10 dB, the band 
below it for about +6 dB. Listen to the result, and tweak the settings 
of the higher bands "by ear."

See you in Dayton?

73, Jim
