General discussion forum / ATT Uverse modem problems

« on: 2014-02-06, 21:26:51 »

This has come up before, but with different versions of their modem/router.  I just switched to this service, and have modem model 3800HGV-B.  I have TV, internet and phone service through the one box.   I cannot get the RRC's to connect through it.  It was all working with my Time Warner service.   I am changing services to get lower latency, which the ATT service does provide.  I was have a lot of trouble with CW transmit errors, as I reported in another thread.

I have changed the SIP port to 5080, and set up the router for pinholes for  5080 (SIP), 11000 (UDP), and 12000 (UDP).

The router has only one entry for each; rather than separate entries for In/Out etc.  Oddly, the 12000 port is listed on one status page as TCP; on the setup paged as UDP, regardless of how many times I re-enter.

I have checked, rechecked all IP addresses; and reconnected with old Time Warner service which I also still have (it connects).

Any suggestion?

General discussion forum / CW Transmission Errors

« on: 2014-01-23, 01:27:49 »

I have recently noticed that my CW transmissions are partially garbled.  I don't know exactly when this started, or what might have changed.  The severity varies from time to time,  but it typically anywhere from about 3 to 30% of characters sent have extra or missing dots/dashes.  The rx audio is quite good during these periods. Here is my setup:

Radio: K3 Twins
RemoteRig RRC-1258 MKIIS, firmware 2.75
Control ISP - cable, 15Mb/s down, 1.2Mb/s up
Radio ISP - WISP, typically 2Mb/s down, 2Mb/s up (advertised rates 750K up/down)
Keyer- external
Key delay = LF delay = 250ms
Audio - 2 x Linear 16bit 8khz

Also have a desktop computer at the remote running NaP3 (with LP-Pan) and some antenna control stuff; computer is accessed with VNC.

I took the control RRC to the remote site to test back to back, and found no problems with the RRC's; CW was solid.  I have done a bunch of ping testing, and the results vary a lot with time of day.  I am pinging the WISP radio unit, as I have not been able to ping anything behind it.

Typically, in the light usage hours in the middle of the day, I can usually do a 100 ping sequence and get 70ms max, 45ms ave, 0 lost.  Sometimes the max will be 150ms or so, with just a few in this range; sometimes there are 2% or so lost.  Testing the CW transmission in these conditions still result in around 3-5% errors.

In the evenings, the ping times do get up into the 150-200ms range, but not often more; there are sometimes 2-4% lost.  The CW at these times is substantially worse.

Can anyone advise how to trouble-shoot this problem?  It seems to me like the ISP performance is not so bad to be causing it to this degree.

Thanks,

General discussion forum / Keyer is a little odd

« on: 2010-11-19, 16:00:16 »

The keyer on my new RRC's works ok, but behaves a bit funky compared to my other keyers.  When I hit dit a little too soon after a dah, it is ignored; no dit occurs.  My Icom, mfj, and k1el keyers don't do this.  Maybe I have just picked up a bad habit.

Has anyone else noticed this?  I will eventually have to re-train the fist or try to hook up a separate keyer somehow.

General discussion forum / Failed to update FW

« on: 2010-11-19, 15:56:02 »

I have new units (stereo) that came with 2.25.  When I tried to update to 2.27 with the Setup Manager, it failed to program.  However, when I ran the update through the web interface, it appeared to work fine (both units).

Any reason to be concerned?

General discussion forum / CW delay with Paddles

What is the delay from the paddle input to the time the rig keys at the other end?  Is it one character plus latency?

General discussion forum / Remoterig with WISP

« on: 2010-10-27, 22:20:42 »

My remote station uses a wireless isp service that has a dynamic ip, and no
public ip address. When I do a "whatismyipaddress" query, I get the ip of the
main office; all subscribers would get the same result.

Is there any way to use the remoterig system in this environment? I don't see how
the dynamic dns services could work. For a fee I can get static and public ip, but  I'm wondering if there are any options.

General discussion forum / GSM codec available?

« on: 2010-07-17, 19:38:14 »

Is the GSM or other low bandwidth codec available for the 1258mkii?  What would be the data rate with overhead be?  For some wireless isp's in this area, even the lowest rate G711 is a problem.
