An Update on the 449.525 Repeater

Bob – KEØSJ, is continuing work on the 449.525 repeater, which is typically linked to the 145.280 machine. We still have an occasional issue with deliberate QRM during the Sunday Night Net, and ongoing QRM from unlicensed operators.

We recently enabled the tone requirement using 156.7Hz, and sometimes need to unlink the repeaters. We therefore recommend using only the 145.280 for the net on Sunday Night.

Maintenance on the 449.525

We’re experiencing some interference issues on the 449.525 repeater. It appears to be a couple of issues. One being a malicious station using 2 radios to generate feedback between the 449.525 and the 145.280, which happens mostly during the Sunday Night Net. The second issue is noise being generated near, or at, the repeater site, possibly a harmonic from non-ham equipment.

As a temporary measure, we have enabled a tone requirement for the 449.525, but this is functional only if the repeater is unlinked from the 145.280. The tone frequency is currently 156.7. If the repeaters are linked, the tone requirement becomes inoperative.

Bob – KEØSJ, will be working on this issue as time is available. The goal is to update the repeater linkage such that the 449.525 can operate with a tone requirement while linked, and also change the tone to 100hz.
