[R-1051] Megacycle synthesizer

[John Gibson]

  I have a problem with my R1051/C. I bought it some 10 years ago for $140
and it has worked fine until now.
 The problem is that it will not receive any 6mcs frequencies. I traced the
fault to the megacycle synthesizer module, where the 23.498120 mcs crystal
has become duff. A new crystal will cost $35 but I do not know how to
specify its properties so that the crystal company can make a correct
replacement. Does anyone have the specs? Thanks.
 Alternatively and hopefully, someone has a parts set and would sell me
this synthesizer. Thanks again.
