Chances are there is nothing wrong with either system. Operating 15 kcs is
really too close for repeaters. Many of them are converted comercial rigs
and the selectivity is not that good in many cases as they were designed for
30 KC spacings.


Here in northern California, repeater spacings in the 2-meter band
seem to be about evenly divided between 15 kHz and 20 kHz, depending on
which portion of the band one is taking about. The local repeater
coordination council (NARCC) mandates the use of narrow-selectivity RF
and IF stages, and peak transmit deviations not to exceed 4 kHz.

The new Kendecom repeaters my group is in the process of putting on
the air, have an IF response which falls off of a cliff at 7.5 khz...
in fact these rigs are very prone to pop or squelch if somebody's
radio is tuned up too hot and is over-deviating past this point.

It'd be nice to be able to count on 30 kHz repeater spacing, but in
many areas of the country the 2-meter repeater subbands are just too
crowded to permit this.
