 === practical matters ===
 There is a Ham radio 'repeater' up on South Ranch Road on the North Ridge.
-This is the '''CMD33''' channel repeater, known in the Ham world as KD6KGE ( John Killeen ). Given the topology of the canyon that's the only one we're able to reach, and then not from everywhere. It's listening on the same frequency as '''CMD31,''' coming up next. ''It's also listening on 442.325 ( CMD33 442.325 + CTCSS 141.3 Pescadero net, linked to Cmd. 31 KD6KGE ) if you're a HAM and want to use that frequency. I don't know if that works from the Canyon.''
+'''this needs editing as it's not right: ie - with a bigger radio we can hear and talk to WA6TOW'''
-So I know this is sorta confusing. KD6KGE up on South Ranch is doing double duty - or perhaps triple duty ( I haven't mentioned the Loma Mar repeater up there!) Let's just pretend we're talking to '''CMD31'''
+So I know this is sorta confusing. I don't think I am explaining it well. ok! KD6KGE up on South Ranch is doing double duty - or perhaps triple duty ( I haven't mentioned the Loma Mar repeater up there!) Let's just pretend we're talking to '''CMD31'''
 This works because'''CMD33''' has a 'private line' to '''CMD31''' W6SCF, which has a great connection to the rest of Coastside. That radio then re-blasts the messages back into the canyon. W6SCF has a billion watts of power, it's set to '''11''' and transmits all over.

-Some folks have FRS/GRMS radios;regular walkie talkies such as you would get at a sporting goods store. The red boxes in the next illustration show which Walkie-Talkie channels overlap with the BaoFang channels. The first channel at the top is Butano Zero - it's a very common walkie talkie channel. The other channels were chosen specifically so that they would not be 'stepped on' by older, regular walkie-talkie communications in an emergency.

 === Yaesu ===
-Brandon and Casey have Yaesu VX-6 radios, which without modification only receive on the defined GRMS channels. The next illustration shows channel settings for Butano. '''BU1-4''' are the 'regular' channels for within the canyon. '''BU UP''' and '''BUPD''' are the Ham radio frequencies for reaching up to the CMD33/CMD31 repeater link up on John's redwoodtree on South Ranch Road.

 === Baofang BF-888 ===
-Mark and _____ have a pair of Baofang BF-888 walkie talkies. Casey programmed one so the last 4 ( of 16 ) channels match the current Butano GRMS channel plan. It seems to be a very inexpensive straightforward [http://www.miklor.com/BF888/888-Manual.php UHF radio]. It does have a scanning capability.
