[hpsdr] TAPR Hermes and ApacheLabs ANAN-10 combination. Help with Soldering solicited.

[Dick Faust]

Hi Larry

Ian's advice is good and should be quite adequate for soldering just the 
2 parts.  If you are nearsighted [like me] take off your glasses and get 
as close as necessary to focus on the parts.  It is imperative that you 
have a clean bright soldering tip every time you solder a joint so use a 
damp sponge or cloth to wipe the tip.
Be sure to have a bright overhead light to eliminate shadows

If you can make it to MISSOULA  there is a Harbor Freight store that has 
inexpensive dental picks, tweezers, hemostats and various magnifiers 
that would also be helpful.  I use the dental picks to position the SMT 
parts instead of tweezers.  In some cases you need tweezers that are 
normally closed to hold a part for examination or transfer to the pcb.
