Re: Digest Number 21
It was the commercial version .. now to figure out which computer it is on .. pretty nice, though. In the midst of changin' from 1.5 MB DSL to 5 MB Cable ... w/ wireless, all that... so slo on uptake .. Kinda like finding OtorMola data.. HIHI May all your chicks be blessed... 73, Mark .. AA6DX

Reports back to the radio via Ethernet can and should beThe radio should support both, the push and pull mode. By default the push mode should be deactivated since not every client might desire (or even be capable to handle) it. I'll up the ante on this and request that the changes which areI completely agree on that. Regarding collisions, ethernet is of course a far better choice as issues are handled at operating system level and therefore will remove complexity from the IC-7000 device driver. However the IC-7800 only uses ethernet for updating its firmware, as I have read. So we can only hope that Icom sees the signs of time and opens the ethernet port for remote control and bandscope samples too. We will see what happens. ;-) Why not allow all functions to be controlled? That would open nice...IC-7000 and the computer...all functions to be controlled from the computer. opportunities. Of course they should be readable as well. But that's already the case for almost all functions today. If the C&R, Control and Reporting, is via CI-V that may beI do not completely agree on that as the CI-V system will also be necessary if you want to connect the IC-7000 to another Icom radio, e.g. to do CI-V transceive. Otherwise you will always need a software or microcontroller that interfaces CI-V with ethernet. But I don't think it's a big issue to keep the CI-V jack and add an ethernet jack too. Of course sending bandscope samples will make most sense for ethernet only as you don't have to take care about the low bandwidth the CI-V bus has. However AOR managed to do that for the AR-8200. You can read the bandscope samples in a packed format via the serial port. But I have not tested how performant this solution is. So ethernet is definitely the better choice for such things.

That is a good impression, Mike. I used to watchHowever, properly mounted PCBs do not vibrate as much with SMT as they do with the heavier leaded components. I believe it's a net win if the PCB is made stiff enough. The chief win is getting resonances out of the range you get within a given vehicle. {^_^} |

Ah yes, that is likely true about the missing analog filters.

Now the time was in the very early 70s. The setting was a small company in Arcadia that was building a Sonobouy receiver for the S3A aircraft. This receiver had 31 individual receivers through the low level audio output, a 31 by 16 multiplexer, and a fancy antenna multicoupler with a preamp from science fiction. (130MHz or so frequency Very high IMD intercept point and a noise figure so low that measuring it required liquid nitrogen.) We were testing unit 1 for shock and vibration. The unit was firmly mounted to the vibration table. It was powered up. And as I heard it some one of the table's jockeys pulled a wire. The table went WHAM against its stops. The poor receiver suffered. About 1/3 of the crystal filters died. Some were degraded. And one degraded and died as I was retesting it after the event. It seems those nice little wires to the plated areas on the crystals in the crystal filters do not like heavy shock and vibration. They tend to break loose. So any receiver that can minimize the number of crystal filters can survive more shock and vibration. This is also a good reason to have multiple first conversion filters that can be selected arbitrarily by the user overriding any automated selection. Not that the 7800 gets much shock and vibration in most uses but it should have this override capability as a redundancy feature that leaves the radio mostly useable while replacements are on order. For military or Homeland Security purposes such a design should be considered a requirement. {^_^} 62 new filters later and that radio was back in business, in theory anyway. Now, I've forgotten how many were replaced. But it was not "62". <sigh> W6MKU ----- Original Message -----

Also, the IC-7000 does not require analog filters so it is mechanically / electrically more robust in theory.

I am under the impression that surface mounted components have less mass, shorter cantilever length, and therefore much, much higher mechanical resonant frequencies than leaded parts. Am I missing something? Cheers, Mike - W8MM --- In ic7000@..., "Tom" <tgleeman@i...> wrote:
