Re: [DSTAR_DIGITAL] ID-800H with water damage
On Mon, Jun 21, 2010 at 10:27 AM, kristof_wanderer My radio got wet during a flash flood, well it was under creek water for a few hours. It was not on during at the time. As I expected it doesn't work. Before I applied power to the radio I disassembled the radio, cleaned the boards, connections, etc. and dried it using a hair dryer for about three hours. I then allowed it to sit in the open air overnight. I reassembled the radio and tried it and it still won't work. Other than buying a new radio, any other suggestions I can try to get the radio up and operational again? Your suggestions are appreciated! First sign of life is the +5V supply voltage for the control head. Measure each pin (as I can't recall which is the +5V) against ground and if you see +5V, the regulator to power the control head which eventually turns the radio on, has it's lifeline available. The regulator is on regardless of the power switch, if the main fuses are OK. I had one ID-800H which had this lifeline dead. There was no voltage although the regulator was OK, as a 0-ohm resistor just before the control head connector in the main chassis was burnt for some reason. It had acted like a fuse, by design. Next thing to check would propably be the power switch itself, as it might not like water at all. If you fail to get it working, I'm interrested to buy the radio for spare parts!

Re: [DSTAR_DIGITAL] 2 meter
James E. Wells wrote: I have a listing for a two meter d-star repeater. Do you still put it in the B band? James KD0AJZ By D-Star definitions, 2 meters should be 'C'. 'B' is for UHF or 440 or so. A is 23cm. Erik OH2LAK
[DSTAR_DIGITAL] Debugging 23cm DD mobile connection back in 2004
I finally uploaded a video from our Dayton Hamvention roadtrip. There was two ID-1's on board, mounted to the trucks of Jim N5MIJ and Bill N5ZPR. Of course we needed a wireless internet connection between the cars. There was a cellular internet access in another car, and they shared the connection to Bill's truck via WIFI, and our truck was then behind that WIFI connection. We had the freedom to wonder around, did not have to stay in close formation with the others as 23cm DD worked OK on the highway over several miles, while WIFI needed a true closed circuit to work OK from car to car...

Re: [DSTAR_DIGITAL] GB3IN goes fully dual-mode
Jonathan Naylor wrote: I'm happy to announce that the first full dual-mode repeater using my software went live yesterday. GB3IN had already been operating dual-mode by means of fixed time periods for each mode, but with the latest version of my software, the repeater is now available for both modes when cold. Sounds great! Could you point us to a webpage or other information source for your project? In brief, the mode of operation is as follows. When cold both repeaters are listening for valid GMSK or CTCSS/1750Hz respectively. Once that has been received, the active repeater tells the other repeater to go into Shutdown. This Shutdown state lasts for as long as the active repeater is receiving/transmitting valid information and for a user definable period afterwards to stop quick mode flipping. Once that period has expired, the Shutdown repeater is brought back to life and the system is available for both modes again. The only duplicate hardware in use are two Velleman K8055 boards, one for each repeater, the USB audio fob and radio are of course shared. Does the code include a sofware GMSK decoderencoder or does it require a Satoshi board to perform as D-STAR air interface? 73 R2D2 Erik OH2LAK

Could not just link these two things together :) Does the code include a sofware GMSK decoderencoder or does it require a Satoshi board to perform as D-STAR air interface? It's all done in software. The interface to the radio is the cheapest sound card you can find, the lack of filtering is a plus, and some sort of I/O board, the Velleman K8055 is favoured. Is the IO for PTT COS or what? We use the CM108 chip with Thelinkbox, a multi-protocol VoIP client, and we can use the 4bit GPIO on the CM108 for the PTT and other digital IO requirements. That could be propably a good approach for you controller too, to get just a single wire from the controller to a radio! 73 Erik OH2LAK
[DSTAR_DIGITAL] D-STAR international WorldNet?
Hi all. Looking through the reflector NET-lists I fail to find a worldwide net as a meeting point for users all around the world (except REF001C as the megarepeater). D-STAR is growing and would need encouraging traffic to fill the newly added repeaters or hot spots in places where D-STAR is still in introduction phase. I partly can speak for my region for such. Being bit unaware of how nets are moderated and controlled, I humbly ask is there a place and need for such, and would there be some skilled operators available to run such net? I can provide a high-bandwidth reflector for the net, and propose it to be active weekly, having three timeslots for the three main continent regions, US, EU and Asia/Pacific. WorldNet could introduce D-STAR users, hot spot and repeater installations worldwide. What u say? 73, Erik OH2LAK

[DSTAR_DIGITAL] Nordic DPLUS reflector REF022
Hi all. There is a new DPLUS reflector, REF022, freshly installed in the Nordic region. It is ment to service the northern Europe and Scandinavian region mainly with low latency, but others are welcome too. The reflector is located in a Datacenter connected to ISP backbones. The module configuration has been decided to be geographically split, so that there can be regional modules with local language; REF022 module A Finnish REF022 module B Swedish/Norvegian/Danish REF022 module C English/other. I dare to put our dear neighbours to same module as they share common language, I've stand next to them and they do understand each other, thus they speak very differently :) The configuration can be changed if need arises. REF022 welcomes all DVDongle users and Node Adapter experimenters, there are no limits of the usage other than to follow ham spirit and good manners. Currently the reflector is in commissioning stage and is not yet open to public other than RX only. It will become open for TRX in few weeks.

They have built a NEW TRUST server. That is the point. Now others will build more, as every country should have one. That is the point. I dont care which repeater belongs to which trust at this point. We will also build another one in the US and another in Canada. We DO NOT care about routing from EU trust to US trust and back. That is not the point I am trying to explain here Who are WE in this aspect? Why do you want to create numerous parallel networks unvisible ro each other? You then fail to understand the whole concept of D-STAR callsign routing. The point is now we know how to create TRUST servers for peoiple to enjoy and repeaters can belong to any TRUST. Is is not any more one ONLY. You see what I mean. And check this out, A dstar repeater can switch from one TRUST to another TRUST in 5 seconds. That is the beauty of it. If one goes down, there is another and another and another ... Why dont you all join your your forces and start designing a next generation trust system which has multiple instances for redundancy but still acts like one so everybody could use it and enjoy a global D-STAR network..

Re: [DSTAR_DIGITAL] Re: IC-92AD Connector
They really should have thought of using some connector which is already available and meets the required specs, waterproof, latching, etc. They are widely available from reputable manufacturers and the RD costs are already paid for. Now Icom designed one of their own and it most certainly is a expensive part. I can't see a proprietary connector as a cash magnet either. What really is funny too, that a radio which is claimed to be waterproof, has a hole in its 'hull' which is covered only with a rubber cap which pops off quite easily. The DC-inlet, that is. The 92 is ok to use in rain etc. but I really don't consider it waterproof. But that is very ok as it would be difficult to work submerged anyway. The ruggedness brings a bit of freedom how to throw the radio though :) Erik OH2LAK --- Original message --- From: Scott [EMAIL PROTECTED] To: dstar_digital@yahoogroups.com Sent: 29.11.'08, 5:33 I'm not objecting to the use of that connector - though it would have been nice if they'd used a readily available connector. It looks a lot like a Hirose LF series, which isn't exactly cheap, but at $12 it's not bad and it's ruggedized and waterproof. If I can get equivalent cables made in lower quantities and still sell them for a lower price after paying for custom tooling, then I think that's a pretty good sign that the price they're charging is excessive. I think there could also be a market for a simpler cable that's not threaded and waterproof. How often do you need a waterproof data cable when you're using it with a laptop that's probably not waterproof?

Re: [dstar_digital] Re: D-STAR Logo
Don't ask, the answer might be no. :) The D-STAR logo does not seem to have (R) or (C) emblems which should be there if the logo is internationally protected by copyrights or is registered trademark. IF it would be protected, there should be already quite good knowledge of such, as for a official logo property of someone has usually also graphical guidelines regarding the positioning, surroundings and limitations of the usage. I've seen the D-STAR logo attached to several other logos and backgroups, which are usually very no-no by the guidelines. Erik OH2LAK
Re: [dstar_digital] Help with poor audio on Dstar System?
The audio sample clearly reveals that something is wrong. Significant information below is that the problem occurs only with remote traffic, not with local traffic which generally outrules local RF equipment failure. I would look more closely the internet connection. Sounds like there is substantial but not persistent packet loss at the internet link now and then which distorts the incoming d-star datastream. The voice data is UDP, which means that there is no proper way of making sure of the delivery of each single audio datagram. I don't know has the gateway software any debug features to reveal this kind of data loss, and if it does, there will certainly be some indications of packet loss. The case could be such, that when the peak data flow on the internet connection reaches about 2/3 of its capacity, the audio UDP packets get queued and not delivered to the gateway in time, or get delivered in incorrect sequence and dropped. These are the usual causes for audio problems when dealing with Voice over IP, which the traffic between d-star gateways and reflectors looks like if not looked too closely. The problem can be local LAN equipment related hardware issue, or truly a capacity issue when your solution would be to prioritize the d-star gateway traffic over the other traffic Hopefully you willl get it fixed! 73, Erik OH2LAK
