On the air
The KSØMAN repeater
- Output
147.255 MHz - Input
147.855 MHz, a+600 kHzoffset - Tone CTCSS
88.5 Hz, transmit and receive - Access open to any licensed amateur
Nobody has re-measured any of it since the machine left the KSDB-FM tower in November 2023 and the controller was voted out of the system in January 2024. The spectrum band across the top of every page is a drawing of this frequency, not a receiver listening to it.
Unverified. No check on record.
The Tuesday net
A directed net runs on the repeater every Tuesday at 8:00 P.M. Central, and any amateur, Technician and above, is welcome to check in. It ran at 9:00 P.M. through 2014 and appears at 8:00 P.M. from about 2016; the old site printed both hours, in different places, for years.
Unverified. No check on record.
Both records in full, field by field, each with its own check date
Every fact on this page says how well it is known and when a person last checked it. How this site is maintained.
Where the signal goes
Drag to orbit the scene, then change bands. On 80, 40 and 20 metres the ionosphere bends the wave back to earth hundreds of miles away; on 2 metres it does not, which is why the KSØMAN repeater sits on a hill.
The propagation diagram is not being drawn, so here is the same thing in words.
On 80, 40 and 20 metres the signal is refracted back to earth by the ionosphere and lands hundreds of miles away. On 2 metres it passes straight through and keeps going, which is why the repeater covers line of sight and nothing more.
- 80m — 3.920 MHz — Kansas Sideband Net
- 40m — 7.260 MHz — Kansas Weather Net
- 20m — 14.290 MHz — daytime DX
- 2m — 147.255 MHz — KSØMAN repeater (line of sight — no skip)
Amateur radio in Manhattan, Kansas since 1976
The Manhattan Area Amateur Radio Society was formed on 7 July 1976, at a founding meeting called to order at 7:40 P.M. by Leroy Buller, KØWA. Before the founders chose a name they chose the noun: they voted to be a Society rather than a club, and the S in MAARS has been deliberate ever since.
We hold the club callsign KSØMAN, we keep the repeater open to any licensed amateur, and we train and turn out storm spotters for Riley County. Under Article VII a quorum is the members present, so the meeting you turn up to is the meeting that decides things.
