Hello Bob:
Use your VTVM and check that you have 5 volts on the connector between the two pins you soldered into the board. The connections are below the board, and you can not see them, and if the solder flowed properly. You need to heat only the pretinned pin (a solid wire), while you gently push it thru the hole, which already has solder in it. If you have 5 volts on the connector, check the jumper cable to be sure it is just fine. If that doesn't work, sounds like you have a bad transister on the board.
Make sure your coax cables are inserted properly and fully. They can be difficult at times.
Good luck and Happy DXing,
Mike

Subject: [1000mp] Roofing Filter
Well I put in the roofing filter, NB mod and a 250 Hz filter. I put it all back together, plugged my Elecraft XG-1 to it and turned it and the radio on. Last week when I got the XG-1 the 50 uv signal gave me exactly S9. With the roofing filter in I got S5. My 9-1 reading was 13 and so I started increasing it. After about 19 the reading stopped climbing and never went above S7. Any ideas?
I've checked to make sure the two wires that I had to solder in were not shorted to chassis ground or together. I unplugged the coax going to J2003 and plugged it into J1 of the roofing filter. Then I took the supplied coax and went from J2 of the roofing filter board back to J2003. So all that is right.
Got any suggestions?
Bob
