That's what I assumed but I saw some blackening on the picture and
just wanted to check. <br>
<br>
We would like to do these, we are currently hung up on another job
availability will improve in the next couple of weeks. Are there
any extra pieces that we could practice on?<br>

The ones we've done here in GB were soldered with SN62. There
isn't much mechanical stress on these, so the softer solder works
fine. Also, the lower melting point allows you to get on and off
the heat quickly, avoiding damage/discoloration to the gold-plated
brass.<br>

Are these intended to be soldered with eutectic solder or silver
solder?<br>

and all, <br>

Rick suggested last fall that the Green Bank machine shop
could assist with fabrication of the new dipoles. We've run
into a snag and could use some help. The soldering expert in
our university machine shop has retired, and the current staff
have not been able to achieve the quality in the soldering we
need for the antennas (see attached). Would it be possible for
us to send the parts for the remaining 19 dipoles to Green
Bank for soldering? <br>
