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.
