Hammarlund HQ-129-X
#25

Worked on the Hammarlund some more this evening. I got the highest band working now. I'm sure the problem is just dirty contacts in the band switch. I have more De-oxit coming, should be here in a couple of days. I'll spray the sections well again when it comes. I noticed that the S meter has stopped working. I am tackling that next. I think it was a short to chassis by one of the wires to the meter. The rubber grommet through the chassis to protect them had completely rotted, and its remains fell apart when I went to pull back the wires. I replaced the grommet, and now am going to replace the wires. Tonight I also tweaked the RF tuning using actual stations at the top and bottom of the various bands, which has further improved reception. It is now VERY good, certainly as good as any of my communications receivers except my other Hammarlunds, my HQ-140-X and HQ-145-X.
