1. The propagation was.....shall we say (because this is a family blog) crap!! 
2. I was in the contest for a grand total of 5 hours today. 
3. There was some down time as you can tell from fact number 2...software troubles, USB port trouble and K3 updates and the list can go on.  (This is normal contest OMG stuff)
4. The attic dipole once again did very well considering the conditions.
5. The evening once 20m closes down I am done as with the poor conditions for some reason 40m has not been a great band for me with the attic dipole. 

Readers, check out the Cyclone 40 in this release:

A new kit from the Four State QRP Group and David Cripe (NM0S)

NM0S’s Cylcone 40M QRP transceiver. Look for it at Four Days in May!

Arising from Dave’s entry in QRP ARCI’s 72 Part Challenge Design Contest in 2010, the Cyclone 40 is an enhanced version of the original design. The transceiver designed for the design contest had 72 total parts, performed well, and won honorable mention. This improved version has less than 100 components and even better performance! The kit features all through hole parts and easy assembly. The receiver is a superhet design with very good sensitivity and selectivity, and tunes the entire 125 kHZ CW segment of the 40M Band – and does so at a comfortable tuning rate. A frequency readout is included so you know where you are at all times.

This is a complete kit, including the enclosure. A high quality board package includes the pc board, front and back panels, the sides, and top and bottom all of which make up the enclosure. The control and jack labels are silk screened in white letters and vividly contrast with the black solder mask, and the holes for the connectors and controls are pre-drilled. The ends are “dovetailed” together making a very rugged, easy to build, and attractive enclosure.

Features and Specifications
