I travel frequently and encounter very good, and very bad levels of internet connectivity. In most cases, dropout, latency and jitter are the greatest issues. I have researched the list archives attempting to define settings which can be manipulated to reduce performance issues caused by 'poor" internet service.

Given discussions on this forum, I have selected some of the setup parameters that may be manipulated to better tolerate internet based issues. I would be interested in learning what other forum members use for settings on these parameters. For example, Key delay ms [0-250] is defaulted to 80 in my initial setup. Recommendations on this forum have recommended using the maximum setting (240ms) for poor internet issues.

I do not have the technical expertise to understand how all the parameters below affect the RemoteRig remote station performance. Hopefully responses to this post will help me, and others.

Many thanks & 73 from Andorra

General discussion forum / WiFi board connection issue?
« on: 2024-02-17, 09:39:11 »
Symptom:
Remote rig/K3/0 WiFi combination not connecting to the internet

Observations:
The Microbit utility does detect the SSID from my Verizon JetPack
JetPack connects to all other devices … just not the K3/0 & RRC
Confirmed I have the correct password for accessing the JetPack
JetPack display does not show a connection to the RRC (but does for all other devices)
Red LED on WiFi module is on solid
Green LED on RRC blinks for about 20 seconds and then solid

Other
This combination with the JetPack has work fine for years
Problem began upon arrival in France a few weeks ago. Radio, etc was transported in airplane cabin inside a clam shell equipment carrier. Not aware of any rough handling.
I have removed and reseated the WiFi card a few times.
Thorough internal inspection revealed nothing unplugged or loose.
I can ping my remote connection and the test packets are satisfactory returned.

Any ideas are welcome

General discussion forum / K3/0 connection to K3
« on: 2024-01-10, 18:02:34 »
I have a K3 at my remote in Utah that has worked well with my K3/0 & RRC boxes from my home in Las Vegas. I’ve used WiFi for connectivity at the K3/0 end. I’m in France for a couple of months and trying to use the K3/0 to connect to the remote. I changed the WiFi settings on the K3/0 to the local wifi. I can’t establish a connection.

The WiFi works well with streaming of TV, etc. I tried ran the connection through a stateside VPN server just in case the problem was some geographical limitations. I receive a trouble-tone, which indicates it is not connected.

I really don’t think anything changed in the configurations. Am I missing something? Should I simply need to scan for the appropriate WiFi network and enter the credentials?

BTW, I am able to ping my remote router so the connection there appears okay.

Thanks

Configuration, RRC 1258 / MIC LED on Control RRC
« on: 2021-06-08, 02:34:32 »
Trying to troubleshoot relocation of my K3 and K3/0 (non mini). All radio control functions work properly, as does CW, but I have no microphone operation. I have tried various combinations of MENU settings (Fpl, Rpl, etc), on both the remote K3 and the K3/0. No joy.

The most significant clue is the illumination of the amber LED on the Control RRC.

What triggers this indication? I've checked cable connections on the Control RRC and K3/0. The only thing different on the remote K3 which has was an upgrade to the KXV3B board.

Ideas?

General discussion forum / Connecting to COX network
« on: 2020-11-21, 20:58:31 »
I have used a Verizon JetPack for years to connect a K3/0 RRC combination to my remote station. Today, I tried to connect to the remote station using my COX cable WiFi adapter. I changed the device name and password in the RRC WiFi setup, but cannot connect.

Maybe COX is blocking the ports I need?

Suggestions?
Thanks

General discussion / WiFi nodes
« on: 2019-02-14, 20:34:56 »
I successfully use a Verizon JetPack for WiFi connections while traveling. Today I attempted to connect to a Wifi network in a resort. The site is password protected ... I scanned for nodes, found the one desired and entered the password in the Microbit ap ... all exactly as I do with the JetPack. However, I can’t get the 1258 to connect. The signal strength of the node is -65 ... the JetPack is stronger, about -35. Thoughts? Perhaps the issue is on the resort end but thought I would begin by asking here.

General discussion / Audio feedback in K3/0 speaker
« on: 2018-11-06, 18:32:44 »
I have recently reconfigured my remote station and seem to have made a minor issue from the past, more prevalent now. When transmitting, I can hear my transmit audio through the K3 speaker slightly delayed. The audio sounds like my SSB signal, without a BFO. Severity is dependent on power levels. At 100 watts, it is loud enough to be quite annoying. Obviously, I’m getting RF into the RRC box or cabling.

All components in the remote box ... radios, amplifiers, hubs, computer, RRC, etc have chassis grounds individually run to a single point of contact (ground rod for electrical service panel).

Given the symptoms, any idea where I should begin my troubleshooting? I suspect ferrite beads are in my future, but would like a sense of where to begin.

Thanks

Configuration, RRC 1258 / No receive audio
« on: 2017-01-14, 23:33:36 »
I have my two RRC's and the K3/K30 mini communicating over the Internet using cellular data. Rig control works fine and I can see the s-meter fluctuating at the remote site, but there is no receive audio. Tried the obvious like the K3/0  rf and af gain, but still no audio. Any ideas from the learned masses?

General discussion / Boot sequence for remote
« on: 2016-12-28, 19:10:34 »
I am successfully using a K3/0 Mini plus the K3, KAT & KPA 500's via the RRC boxes. I also have a PC connected via Team Viewer which talks to the configuration via serial ports. I'm connecting an IP power strip, and curious as to the best boot sequence to program so everything is 'awake' when hardware and software are trying to communicate. I'm thinking the following order, but would welcome suggestions:
1. Web router/hub
2. RRC at remote site
3. PC
4. 12VDC bus that powers radio and radio accessories

Configuration, RRC 1258 / Multilevel passwords for WiFi
« on: 2016-03-21, 18:52:14 »
I'm in Mexico and trying to access my home station in Washington state. The ISP here requires two entries to sign in. I can see the local wifi on the RRC, but the RRC firmware allows only has one field for the password.  The wifi network asks for a room number and a last name (2 separate items in two different fields).

Any ideas how I might get around this login issue?

Cheers,K7FL

General discussion forum / Acceptable jitter
« on: 2016-02-17, 00:03:10 »
I have identified a potential host QTH for my remote with great bandwidth, but the jitter is 13ms. Jitter on my current remote site is 1ms and I've been successful with running CW on the RRC with the default jitter settings. As there are no antennas or power at the new site, its difficult to test the significance of 13ms jitter on my operations, and if the 13ms of jitter can be mitigated by RRC settings.

How bad does line jitter need to be before causing issues on CW? I understand there may be other variables, but I am trying to determine some rule of thumb about levels of jitter found to be problematic for users. The archives have lots of info on addressing jitter, but few reports of the measured jitter users are trying to mitigate.

Configuration, RRC 1258 / Congestion tone on first setup
« on: 2016-02-12, 02:23:51 »
I have my Elecraft K3s communicating effectively over the LAN and am now attempting to connect over the Internet. I have enabled port forwarding on my firewall for 13000, 13001, 13002, and 80 and the RRC shows "Idle" status (see below). However, the K3s still gives a congestion tone when turned on. Everything is physically connected as normal but the AUX/MIC shows no link or activity lights.

Any pointers would be appreciated.

General discussion / Typical data usage?
« on: 2016-01-29, 21:07:44 »
I have a K3, KAT500 and KPA500 with the K3/0 mini and RRC boxes. What kind of data consumption might one expect from this configuration? I suspect that's a tough question with many variables, but lets assume the radio is on and receiving for  24 hours, limited knob twisting and transmitting.

The reason I ask is that I have multiple host sites for my remote station. Some have great Internet access (Comcast high speed cable), others ADSL via WiFi, and one with a 4G Jetpack. All of these options have bandwidth, latency and cost implications. As a CW op, latency is a critical factor in my case. ADSL in my area is typically 10Mbps down, 600Kbps up ... probably acceptable from a bandwidth perspective. One of the best QTH's under consideration obtains their Internet connectivity via a Verizon 4G Jet pack. The bandwidth is probably adequate, latency is around 60ms (in their installation), but the data charges can be significant. But, it all depends on how much data I will actually consume (my question above). Any ideas?

Thoughts on these different connectivity options (cost, bandwidth, latency) are most welcome.

Kind Regards,

Configuration, RRC 1258 / Control RRC is confused :-)
« on: 2016-01-11, 00:45:38 »
I had to reboot the Control RRC  a couple of times today. After one reboot, the rigs failed to communicate and investigating, I found the Control RRC has somehow renamed Radio. In addition, the original serial number now indicates a 1. I reloaded the firmware to no avail. No communications between the RRC's, but I can ping each IP number.
