[1000mp] HELP on INRAD Roofing filter Mark-5

[Mike Schatzberg]

Hello Dick:

You may find it easier to remove the insulation totally from the 22 AWG
"Solid" hook up wire.  Then, pre-tin the end of the wire you wish to insert
in the board with solder.  Holding the other end of the pre-tinned wire,
apply heat only to the solid wire itself, fairly close to the board, while
holding the wire against the closed hole.  The heat will travel down the
wire on to the solder pad, and will eventually melt the closed pad, allowing
you to gently insert the wire below the board surface.

Do not push the wire too far into the hole, just an 1/8 of an inch or so
below the board at most.  The solid wire mates to the connector on the mod
board by friction only, and must be sturdily mounted for its intended
purpose.

The solder should melt within about 3 seconds or so if you have a square end
on the wire and have carefully pre-tinned the wire.

It only takes a few minutes to get the ground and necessary 5V for the mod.
Generally, the coax will reach in the Field, while it may not in the 200
watt radio.

73 and Happy DXing,

Mike
