General discussion / Re: Audio feedback in K3/0 speaker
« on: 2018-11-07, 21:24:47 »
Resolved ... part of the chassis ground bus had became dislodged. Reconnecting all commons removed the feedback.
Thanks for the help

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, Iím 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.

More info: receive audio is heard at the station (RF) end of link  ... nothing from the K3/0 through speaker or headsets.

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?


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.

Solved! I had forgotten to enter the SIP password. So obvious !!!  :o

We used the actual IP address.
More suggestions welcomed.

Yes, we changed to the external IP address. The control RRC is not using DHCP but we did change the IP address to the correct subnet so it is visible on the local network.

« 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.

Here is the status from my control RRC:

Thanks Mitch. My apologies. I did a search but must not have selected the correct key words.

I'll go to the link you suggested and research.

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.
