Free* – As a retrofit to an existing Mortty CW and RTTY Keyer kit

Free?!? Read the fine print… Steve and Larry struggled with pricing for the retrofit MorttySP accessory, because the cost of packaging and shipping the kit is more than double the cost of its five components. Here’s what you need to do for your free retrofit kit…

  • Step 1: Mail a self-addressed business envelope with simple first-class postage (a Forever Stamp) applied to Steve, N8AR (see QRZ.COM address). He will return to you, for Free, an envelope containing three of the pictured components: the MorttySP circuit board, a new label, and the teflon wire.
  • Step 2: Look at the parts list in the MorttySP assembly appendix. Note the Arrow Electronics part numbers for the speed potentiometer and 6 pin header. Arrow provides Free Shipping, so your total out-of-pocket cost for the remaining two components of the kit will be around $3.00. Not quite free – but as close as we could get without having to charge you another $7.90 for shipping!
