2K, 4K or 8K EEPROM support for the X9000 ?
|
If we support an 8K EEPROM on the X9000 and we don't have enough pins left to do Doug Hall, or CI-V.
Do we really need 8K support ?? If we only support 4K then we will have 2 pins left that we can use. If we only support 2K then we will have 3 pins left over. I'm assuming that if the radio has a 8K EEPROM we need the entire 8K and can't just cheat and only support 1/2 of it.? Of course we could change the EPROM but... What's most common in the "market"?? 73's Skip WB6YMH |

@ Skip,
Was already thinking on that........ What if you made the genric protocol an option in the initial settings? If selected only 2k codepulgs are available. Same at the SyntorX/Xcat. To support 8k codeplugs deselect Doug Hall support and re-use those GPIO lines as needed. .I dont know the major config for existing Doug Hall installations, but OEM Xcat is (2k)? 32 mode limit as built. Do they use mode selection for frequency control or primarily VFO mode feature? All the oter feature should be unaffected. |

Frankly I don't know how existing Xcat owners are suing their Xcats.? Personally I have two use cases:
1. Code plug replacement for my 440 base.? I used the pre-prorgrammed modes 99% of the time but I kept the Xcat connected to my PC so I could tell at a glance what mode was active when scanning.? I also used the VFO capability from time to time. 2. As a "remote base". I used the CI-V mode exclusively with my own software (/g/thelinkbox).? This mode of operation use to be a big thing in the 70's but has largely died out in my area. I know there are a number of people using Xcats with Allstar systems for remote base operation, AllStar uses the CI-V interface. I know of a couple of people using the Doug Hall interface with commercial repeater controllers. I now of ONE person that used the Xcat with a Palomar/Cactus controller.? (BTW the Palomar mode is flaky, the Palomar keyed the radio and THEN changed the frequency.? This causes the Xcat grief since it can't process sync data WHILE the Syntor is actively reading the code plug). I know of no one who is using a Xcat in a mobile, but I assume there are some. 73's Skip WB6YMH |
开云体育guysvery interesting following your ideas. dont fully understand everything you’re talking about but i’m big into syntor 9000s. most out thete are 2k 32mode so if you have one of the modes a vfo mode then 2k should work for most folks. ? jeff N2IA On Aug 13, 2022, at 12:24 PM, Skip Hansen <skip@...> wrote:

I bought 3 low band units surplus and they were all 2K from the surplus. I immediately updated to 8K 128 mode. but still have original firmware.? I have several other radios from another ham and suspect they are 8K upgrades. So a bit of a mix depending upon if you buy surplus or from ham.? the control heads are another issue. Some are difficult to bump to 8K thus limiting them. I think having both options is a benefit. my use will be mobile and base, but not remote base control.?

I know at one time the Doug Hall Controller was quite coveted, and if you found one available expect to pay a premium for it.
That was before the numerous uc repeater controller projects were published. I expect there are a lot of lrgacy stand alone installations out there just chugging along as expected. Being as full featured as possible is always a good thing (from the end users side of the equation) I too have no idea the most used features for Amateur installations. You've met the equal compatibility design for the Xcat with 2k support. The X9000 is really the only application where not having 8k codeplug support could hinder it's abilities. It may be possible to use in 2k configuration if Doug Hall support was required. Looking at the addr lines used, 1k emulation operation is not possible for the X9000 to be compatible with OEM RSS, and maybe not at all. In the OEM configuration for a 2k EEPROM, the PL data storage area is above the 1k boundry. |

The Doug Hall controller for the radios was a rare thing in 2004 when I designed the Xcat.. It's the INTERFACE that's interesting because most commercial repeater controllers support it.? Doug Hall is actually an extension of the "BCD" interface that predated it.? The "BCD" interface was just a couple of CMOS shift registers that were wired across the BCD switches that some old radios had.?
Other than "real" radios the BCD "programmable" Kenwood tr7400 was one of the best two meter radios of it's day and more than a few found their way to local hilltops.?I had one on my packet BBS for YEARS and it was still working when I got out of the packet racket. Again it's amazing we're still talking about Syntors !!? I wonder if the engineers that designed them have any idea! 73's Skip WB6YMH |
