Re: [Repeater-Builder] Re: 900 meg Spectra radio
That's because Joe halted the development. He pleaded with potential users to interface it with their choice of radio. I was the test for the Delta-S low band. There were several other volunteers who did other radios. As each one was proven to work, Joe added the programming for that particular radio to the microprocessor. It was a work in progress. There were several memories (can't recall how many), scan, etc. You could change to a non-memory frequency on the fly if you desired. Maybe Doug Bade remembers, I think this work was back in the late 90's.

Re: [Repeater-Builder] Re: 900 meg Spectra radio
The reason it died was more apathy in the amateur world when a ham can buy a full featured vhf or uhf or even 6m radio off the shelf that did more for less and required no surgery... Joe and I had discussions on porting it onto 900 radios at the time which were only available as commercial feature starved radios( mostly with no mods available at the time like we have now) and at the time 900 was such slow growth.. no one chose to show interest. If you look back in discussions on ar902mhz you will find queries of interest.. there was none so the project was never pushed... What needed to be done is build a self contained head and finish it as a complete unit.. it was not really complete although it was operational. Some of us had issues when we tried to remote control a radio from a remote head as the line drivers had poor immunity to noise... Most assembled were hand wired as boards were only available later in the project.. A replacement project is worthy ( and quite doable ) but I am not sure Joe would care to participate.. as he was pretty dejected about the reception by the amateur community... Timing is everything as they say... Many radios such as Maxtrac and almost ALL the GE-et-al 900 radios share a common PLL chip.. it is not magic to program Doug KD8B At 02:50 AM 3/2/2010, you wrote: Oh, BTW, I saw nothing for the Spectra there.

Re: [Repeater-Builder] Re: 900 meg Spectra radio
It was not a single channel device it had at least 10 channels... It took over the radios pll from outside so radio channel programming and capacity was irrelevant... It also had scan, simplex offset and a few other amateur features... I was involved in application testing on a few of the radios under my first callsign of KB8GVQ as well as Jim WD8CHL... It programmed the pll chip that runs the synthesizer by isolating that in the radio... the radio though it was on whatever was in a particular channel and the PLL was actually wherever Joe and the User wanted it... The reason for different versions was it had to account for how a given PLL was programmed and the offset differences based on the IF for receive.

Re: [Repeater-Builder] Re: 900 meg Spectra radio
Maybe that could change in light of the situation. But, I was talking more about looking at the hardware and creating a new source for it. Of course, if the original is still available, that would be fine, too. Joe M.

I don't know anything about programming the chip, but am pretty sure you'd need the source code in order to make changes. Joe programmed the chips and wouldn't release the code - he didn't want someone to steal his idea.

RE: [Repeater-Builder] Re: 900 meg Spectra radio
Joe, Newer Spectra radios are capable of MPL (Multiple PL). Of course, you can only program 16 different PL/DPL codes, but it's better than one. This is what I have - I went through the list and chose the most commonly used ones. IIRC, this will give me access to about 85% of the 900 repeaters nationwide. Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of MCH And put an external CTCSS/CDCSS encoder on it? There are more tone/code combinations to fill 128 channels on a single frequency. Joe M.

Yes, but Joe's control head was frequency programmable on the fly as was the tone.

Re: [Repeater-Builder] Re: 900 meg Spectra radio
There was, but it's all gone now. At one point a link to his site was posted on the Repeater Builder site. Joe made several posts to this list and became discouraged at the lack of interest.

Interesting. I wonder if there is some tech info on this that is available. Any idea how much the cost was and what mods were required? Or, perhaps some tech data on the synthesizer as far as what pins control the frequency, as well as any binary-to-frequency info. Joe M. Chuck Kelsey wrote: > > > Joe Burch was his name.
