Look in the files section of this group. I posted a design for an FM900 compatible encoder tone encoder some time ago. Uses readily avaibale components. I...
Hi Darryn The only way we can really help is (as Mark asked) if we know which version of the "FM92 A bander" you have. If you look at the rear of the PLL,...
In particular, look for FM92Tone.zip, and possibly FM92Encode.doc in this yahoogroup's files section. I haven't built one yet, but Ron's CTCSS encoder looks...
Thanks Ron, That was the sort of thing I was looking for. I don't suppose any kind soul has done a board run and made them available? If I read this correctly,...

Isn,t an MSR9000 a Motorola product used with a repeater ? Cheers....Matt. ... From: Steve Sharp To: FM900@yahoogroups.com Sent: Monday, September 04, 2006...
... the radio in question all printings/ Markings are enlarged any further questions please ask I will try to answer all questions as best I can Thanks Darryn ...
Does that mean you will be running the net ?? Cheers....Matt. ... From: steve s. To: FM900@yahoogroups.com Sent: Monday, September 04, 2006 9:41 PM Subject:...
I just hand paint up a board as required - takes about half an hour to make a board. You also have to burn an eprom. I do have a later version which is...
Hi Mick, you would need to supply more inofrmation than that. You need to supply the HW and SW codes for the radio as well as the frequencies required, both...
Hi Darryn, Yep, certainly looks like a Philips FM900! Both boards look pretty standard to me with an I/O kit and maybe a tone encoder module or similar at...
Hi Darryn Photos are pretty good.. I can make out most of the detail and as far as I can tell, the reference divider links are already set for 12.5 kHz channel...
HI Chris and Mark and others The board is an Issue B or 8 which ever it looks like the freqs on the cover range from TX= 162.1300 to 169.4650 and RX range from...

Hi, Yes you can put 123 Hz on all repeater channels, though you may well have people constantly telling you that there is a hum on your signal... (some amateur...
OK on the ecthing problems. I think it would be difficult to make one using vero board. I'll do a deal with you. I'll send you a board and all the details...
... Or whatever tone... Seems we'll have a mix of 91.5 Hz and 123 Hz on repeaters around the place. I am planning on using 91.5 when I find the data sheet...
Hi Darryn Hmm, looks your "A" bander was modified (or had attempted mods) sometime after the original 25 kHz channel spaced programming (as per your label)! ...
Further to my last post and re 123Hz tone, I just remembered something. One of our local repeaters (VK7RAF)uses 123Hz to switch on the link to another...
... Repeater owners who don't stick to established conventions can be a pain. We have a similar situation with one of the repeaters here, where 123 Hz opens a...
That's a worry - many Foundation operators using radio's I've programmed for the NERG could be accidentally activating cross band links that they aren't...
... VK3RAD is the system in question (438.525) that uses a 123 Hz tone to activate the 6m link. ... I recall, I was at the same meeting. ... Good idea. :-)...
