Configuration, RRC 1258 / Icom 7100 CIV control

« on: 2013-07-10, 09:32:42 »

Hello,

I have acquired an IC-7100 and wish to use the control head ( which is on COM 0 ) and the CIV from the remote unit at the same time so that I can use HRD or any similar logging program to get the frequencies and modes of the remote unit into the computer. I have tried to configure this arrangement but the CIV backhaul that I use with the IC-7000 is precluded as it requires to place COM2 logically in parrell with COM0 at the control which is in conflict with the IC 7100 configuration.

Ideas please??

General discussion forum / Recover Control/Radio Unit

« on: 2013-02-23, 06:11:00 »

Hello,

After upgrading to 2.66 on the radio unit of RRC-1258, first time it worked fine. Next time I could not connect so I tried
http://xxx.xxx.xxx.xxx:portnumber/setrrcdevice?type=radio and that did the job. However it is important to note that the port number is also required if the RRC is behind a router.
Thanks, saved me a 400km trip

General discussion forum / Cmd Latency, delay to start.

« on: 2012-02-19, 07:06:53 »

Hello,

I am using HRD to connect to a remote IC7000. RTP status is excellent (60), UDP cmd status is OK(45) and the audio and CW work very well with RX jitter buffer size = 5, RX jitter delay 3 and packet size of 6ms.

However, when using the tuning via HRD there is always a delay to start (of up to several seconds) and after that the tuning (or any other HRD control) runs very well. If I do not tune for several seconds, then the same happens again with a delay to start.

Using HRD on a IC 756P3 locally at the same baud rate the issue described above is not evident at all so it is not the computer or HRD. If I connect a laptop at the remote site using HRD this issue is not evident at all.

There thus seems to be an issue when there is a higher latency with serial bandwidth allocation although the audio is great with no breaks.

Is it possible that a permanent allocation of bandwidth can be made for the UDP cmd function so that when tuning starts there is no latency while bandwidth is allocated for the cmd/ serial functions. Even if zeros are sent if there is no serial traffic just so that the bandwidth can be permanently held for the serial functions so that tuning using HRD starts instantly please.

Thanks for a great product.

Configuration, Webswitch 1216H / ddns.remoterig.com capability for the web switch

« on: 2011-12-08, 07:49:49 »

Hello Mike,

Is it possible to include the ddns.remoterig capability (as in the RRC-1258) in the web switch instead of just the other host name systems as at present please.

Configuration, RRC 1258 / Remoterig FREE Dynamic DNS service

« on: 2011-12-04, 03:11:57 »

Thank you for this service.

After upgrading to 2.48 in control and radio units,I followed the instructions in the user manual A17 to the letter. But, after pasting the "own host name" into the SIP contact box of the control unit, and restarting it, the green light (pwr) blinks and I cannot contact the remote radio unit. Reverted to DynDns host name in the SIP contact box and all OK.

Ideas please.

General discussion forum / Firmware Upgrade Problem.

« on: 2011-05-03, 08:27:09 »

I have upgraded from V2.33 to V2.37 on both control and remote units.

The audio functionality seems to be better with V2.36 and 2.37.

All runs fine except when the link drops out,... I get a continuous single tone beep and I cannot connect again. I need to restart both units to get connected again.

Revreted back to V2.36 but the same problem is evident.

Please advise.

Configuration, RRC 1258 / Real Time Modes, Timing Issues

« on: 2011-04-27, 13:06:41 »

Hello,

I am running a RCC-1258MkII control and Radio unit over a 3G network. Settings are; Jitter Buffer 5, Jitter Delay 3, Audio Packet Size 40ms, Audio quality 1. This works fine most of the time for classic audio with some drop outs, but the unit seems to be able recover from a poor connection, it never locks up and I never have to reset anything.

I also run a chirp radar and use the remote site as the receiver. The chirp is a continuous signal of 500Hz to 2500Hz repeated every 1 second. In the chirp receiver (implemented in Spectrum Lab)  the timing of the received signal is very evident as a change in delay of the signal will cause the received chirp to jump in time causing a shift in the received signal. For some reason the system often gets itself very tied up with many time jumps and truncated chirps (especially for tone type signals), so that if I stop the chirp transmission I hear bits of the received chirp ( but not complete chirps) for several seconds after the transmission is stopped. If I start transmitting a chirp again the system still has the same problem. The only way to recover from this situation is to reset the Radio unit, reseting any of the other components in the system will not overcome the lockup problem. Thus, it seems that the radio RCC unit does not handle such realtime signals very well, the time jumps and signal truncation are very evident and recovery from this situation is difficult.

Is it possible to modify the way in which the packet buffering occurs so that for real time signals if there is a packet loss then it is not buffered at all but the time base is kept. There is clearly some issue with tone signals when compared to voice.

Hardware, Cabling, Installations / OUT0 mode "connect"

« on: 2011-03-06, 10:03:11 »

When using the out 0 mode "connect" to activate a relay when connecting to the remote device, I use a small low current relay to drive a much larger relay to turn the DC on to the rig. My setup is solar so need to turn the rig off when it is not in use. All fine.

However, when I turn the rig off by disconnecting the control RCC, the remote relay does not always release so that the rig does not turn off. I traced the problem in the remote RCC to the doide D10 connected between the drain of T1 and the 8-9V. What happens is that when T1 goes open, 12V from the hot side of my small relay feeds current via D10 to the 8-9V line with sufficient current to hold the small relay. This will always happen if an external higher DC voltage is used from the external relay.

Thus, I cut the track between the drain of T1 and D10 to stop this current from the 12V relay going to the 8-9V line and all is fixed.

Further, I cannot see any reason to have D10 connected in such a fashion as it does not seem to serve any purpose.

The RCC control and remote and the relay control work just fine without it. If a larger relay is used with a lower coil resistance then the current may not be enough to hold the relay closed but the coil voltage will be fed back into the remote RCC and on to the 8-9V line, which is probably not desirable.

Ideas ??

General discussion forum / PC CW using DM780 and DTR serial signal

« on: 2010-12-07, 01:14:32 »

I have an Icom 7000 remoted via a Telstra 3G connection... all works fine. I am trying to use CW from my PC using the DTR signal. I have tried all possible configurations but I cannot get the CW to work from the PC. The paddle CW works fine.

In the light of all my experiments, I do not understand what "To activate keying the PC could use the DTR signal in the
virtual USB COM-port delivered by the RRC USB device." means (handbook P53, USB- Control-RCC:) Further I do not understand what "USB DTR as CW" in the IO settings of the control means.

As I am using icon CIV (COM2 mode - logicall parallel with COM 0)I assumed that the DTR signal on the rear comm port would be used but this does not appear to be the case.

Where is the DTR connection for CW on the control RCC?

General discussion forum / Dream device, Thank you Michael!

« on: 2010-11-07, 00:40:42 »

The remote rig controller works just as claimed, it may take some time to work it all out but it is worth the effort. The networking issues can easily trap an unsuspecting player !!! The tuning using HRD is great! If you are using a 3G connection and the audio is breaking up, ckeck your signal level and get a good antenna, a good radio connection is critical.

I am using 2.26 with DynDns, IC7000, planning on solar power. The IC7000 is easily turned on and off using a relay and the Connect IO, turns the rig off if the connection is lost and on when you connect.

I am looking forward to many hours of fun using a remote site.

General discussion forum / No Received Audio

« on: 2010-10-30, 07:11:23 »

I have just received RRC-1258 radio and control units. System works great, IC7000, can transmit with audio with PTT from mic, can control unit with HDR, can even hear the quantisation noise if I use audio quality 0 (alaw 8kHz). Can hear beep on connection and can see IP activity with unit receiving audio packets (can see activity on the router).

But, even connecting the LAN back to back with not router or LAN device  (all works as before) the receive audio is not available.

What connection is missing.

Build Oct 28 2010 10:44:31 for both units.

Any ideas out there ??
