900 MHz Repeaters in Southern California

Chances are, you've already visited RepeaterBook. Maybe even SCRRBA too. These are my go-to sites as well. If you look real closely at the listings for 900 MHz, you'll notice that a whole lot of entries haven't been updated in a real long time. Many of the repeaters listed have been off the air for years. What follows is my attempt to pull together a list, that I'll try to keep current, of machines that have been verified as still being on the air.

If you know of other 900 MHz machines in the Southern California area that are alive and well, please feel free to drop me a line!

Many thanks to the following folks for all their help: Chris (N6LXX), Spencer (NN5W), Rob (W6JET), Brett (KK6MOS), Patrick (AD5MT), Ron (K6RET), Steven (KC6KGE), Mark (KD6WLY), Marshall (N6RTR), Cam (WA6VVC), Neil (N6VHF), Pat (KA6P), Paul (KA7LFX), Ed (NO6ED), David (NZ6D), Tom (KN6KS), Greg (WB6ZSU), Ken (WA6OSB), Nick (N5ICK), Mike (N6MIK), Alan (NN6Z)

And, of course, thanks to everyone who works so hard to keep these machines up and available.

73 and I hope to run into you soon on 900 MHz! de Brent, WY6S

Notes:

A - The standard split for 900 MHz repeaters is -25 MHz. Unfortunately, many primary inputs suffer interference from the spread-spectrum devices we share the band with. This repeater has a secondary input (shared with other repeaters) that is further-removed from that interference. Portables and other low-power users who are having trouble accessing the machine on the primary input are encouraged to use the auxiliary input. (cf SCRRBA Band Plan Note 2 for additional information.)

B - This repeater is part of a linked system. Click on the call-sign for more information.

C - The ARRL bandplan for 33 cm sets aside 927.500 MHz as the FM simplex calling frequency but acknowledges that regional variations in band utilization and the distribution of noise sources may lead to regional alternatives. In Southern California, the SCRBBA bandplan for 33 cm allocates 927.600 MHz and 927.800 MHz for FM Simplex - neither is designated as a ``calling frequency''. Anecdotally, folks out here do respond to calls on 927.500 MHz - if you only have room for one simplex frequency, this is probably the one to program.

D - 100.0 Hz and 151.4 Hz are commonly (but not exclusively) used on simplex frequencies to differentiate amateur signals from extraneous background. For P25, I'd recommend using the default NAC ($293) and Digital CSQ.

E - This repeater is connected to mmdvm servers.

F - Analog users on the auxiliary input to this machine are asked to please enable HearClear.

G - This repeater utilizes HearClear.

H - The N6LXX machines on (Sunset and Blueridge), (Harvard and Flint) are operating in simulcast.

I - This repeater may be down. If you know more, please drop me a line!
