Thanks again for all the on & off list 
replies. I looked at the options and 
decided to go with the Green Heron 21D 
controller with the larger readout & an 
Alpha Spid RAK. I thought about the big 
RAK but don't see me needing it for a long 
time, if ever. 

Climbing isn't as easy as it used to be 
(Do need to oil the leather on my climbing 
belt) and I'll most likely be getting a 
motorized tower, likely a pole type tower 
so I can lower the assembly & get to 
whatever work needs done easily. It'll fit 
well on that & if I do get a conventional 
tower, it'll work in that as well with 
plenty of torque. Just ordered a bottom 
mounting plate which was shipped today. 
I'm good to go.

Thanks for the helpful advice.

& totally unrelated... it's been years 
since I had anything but a computer 
generated QSL card. I came across a 
creative artist & the rest is history. I 
have a copy of it near the bottom of my 
QRZ page. It's good to have a fun card for 
a change.
