I'd normally reply direct but there has been a sporadic "K3 and hearing aids" thread on the reflector so it's not "wasted bandwidth." Getting used to hearing aids takes time, especially these days because most are wonders of DSP microelectronics and do some amazing things. Mine have 5 "programs" for different conditions, and they switch automatically -- that's good. Both ears don't always switch at the same time, which isn't quite so good. You could probably buy a couple of fairly well appointed K3's for what mine cost. They'll even notch a fire truck siren down to an acceptable level. Hearing aids won't make things sound like they did when you were a kid and could hear well [except when Mom was calling you], their goal is to make things more intelligible for you. For nearly all males, hearing loss starts at the higher frequencies and proceeds downward as you encounter birthdays. Your audiogram is thus very likely a curve that slopes downward as frequency increases, and the aids attempt to invert that curve and what you describe is a direct result of that. You'll get used to at least most of it, you're just not used to hearing those higher frequencies like you did when you were a kid at first. However, there is good news if you have a K3 ... very good news. Take the aids out when you operate. If you're comfortable with headphones, use them, it works much better and with a boom mic too, you have two free hands. Then find a rag chew going on [75 at night has a number of them, the content repeats and is usually medical, just pick the disease you want to listen to], go to MAIN:RX EQ 1 in the main menu, and start adjusting the equalizer. There are 8 "bands" which you select by pressing the number keys and the VFO A knob will vary the level of that band 16 dB up or down from zero [32 dB total range]. You're going for most intelligible sound, not necessarily "most natural," since you no longer know what "natural" sounds like. It will take some playing around, and you have to give yourself some time to adapt to the varying conditions on the radio. But, if you stick with it you will be surprised. Wayne, Eric, and the E-crowd did us deaf-ies a big favor with the RX EQ feature. I have no clue how to adjust the TX EQ, and I get very good audio reports with it just flat. But you can really improve things with the RX EQ. Just be patient and adjust things in small steps and then wait and see how it plays for you under different conditions. If they weren't busy doing radio things, I'd ask for some equalizer memories ... when I found a configuration that seemed to work in power line QRN, I could save it and recall it instantly. E-Crowd: I'm just illustrating, not asking :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 2010 Cal QSO Party 2-3 Oct 2010 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
