Just a note that is slightly off topic: For those of you looking for a way to reduce distractions while picking out those weak signals from the ether. I picked up a set of passive noise reducing ear 'plugs' made by Shure for about $100 from CompUSA (originally for my palm/mp3 listening) and I'll have to admit, that they do a pretty incredible job at knocking out environmental noise (my guess is in the range of 20-30 dB) like a good pair of foam ear plugs. Also, the build quality on the cord, plug, and Y are excellent with what appear to be solid strain relief.
For comparison, I do have a pair of 1st generation Bose 'quiet comfort' headphones that are great for listening, and are excellent for low frequency noise reduction (bus/airplane engines), but are susceptible to RFI (even after using a couple chokes from RS to reduce RFI on the audio cord before the circuit), but these newer ear plugs from Shure are about 1/3 the cost, have no active circuit to be susceptible to RFI, and put no pressure on my ears or my glasses. I've been able to comfortably wear the ear plugs for over 3 hours just this morning while listening to music at work, and there is no discomfort to speak of. Although my Field Day operation will be limited this year, these are definately going to the field with me. Just so you have an idea just how well these work - my wife was calling for me in the house - and I had no idea she was looking for me until I 'saw' her come through the door (with a less than pleasant look on her face). So - buyer beware - these ear plugs might reduce too many environmental "distractions". 73, Daniel AA0NI Oklahoma City _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
