Can't Build the Kit Yourself?

Elecraft has compiled a list of hams who specialize in building kits for those who cannot build a kit themselves. Some of the hams on this list specialize in Elecraft kits, but some will build any kit.  Please note - if you make arrangements with a builder on the list to build your kit, your agreement for assembling the meter is with the builder and not with MeterBuilder.

Thanks to Elecraft for sharing this list with us.
