Title: WTB; Drake R-4C 3rd Mixer LO Crystals Post by: w9ac on May 31, 2011, 02:01:22 PM In the process of drilling holes in the chassis of an R-4C to install a AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
GUF-1 1st I.F. filter, I managed to let the drill chuck come in contact with the 3rd Mixer LO crystals. I have confirmed that both crystals have shattered as a result of the extreme vibration. Soooo...anyone have a crystal pair from a parts unit? Specifically, they are: 5595.000 kHz 5644.999 kHz. These are the two crystals mounted on the mode select switch PC board (under the mode switch cover). Many Tnx! Paul, W9AC |
