General discussion forum / AS-1289 Port Isolation
« on: 2019-05-22, 15:10:46 »
There's not a dedicated forum for this device; this is the closest topic area.

I don't see a published port isolation spec for the AS-1289 5-way antenna switch.  Anyone have this?

Ability to completely stop the audio stream in the RRC setup menu while keeping rig control.  For example, if WSJT-X is running at the remote site, VNC or TeamViewer can be used to control the program.  An audio stream from the remote site back to the control point isn't required and serves only to waste data bandwidth.  This feature request affects those of us on a monthly 4G/LTE data plan. Lots of monthly bandwidth is presently wasted when using digital modes.

I have my RRC units working fine with N1MM Logger+.  N1MM+ is loaded on my PC at the RRC Control point (not at the RRC Remote Site).  N1MM-generated CW has perfect timing.  However, if I use my paddles while N1MM+ is running, CW stutters.  I'm using a dual Elecraft K3 rig configuration.  Any ideas?

General discussion forum / IP Tracking Software
« on: 2018-07-15, 16:52:27 »
Can anyone recommend an IP tracking software package that monitors and reports inbound IP usage to a remote site?  Ideally, I would like to monitor at the router and have the software report the amount of daily/weekly RemoteRig data, as well as RealVNC, TeamViwer, etc. being used on a per user basis.  I see a lot of products out there, most of them quite confusing.  I would like any information from anyone actually using such a package.  Thanks. 

General discussion forum / RRC Failed Link LED
« on: 2018-07-08, 17:33:25 »
The amber Ethernet "link" LED on my RRC at the control point is no longer staying lighted.  The green "data" LED does show data.  I can connect to the remote RRC but no audio and control is erratic.  Another user is remoting in to the site just fine.  So, the problem is on my control end.   

I've done a hard RRC reset, changed cables, different gigabit switch ports, and reset all network LAN devices.  No good.  I took a big lightning hit four weeks ago and it took out many items on the LAN but the RRC has been OK until now.  To help prevent lightning damage on the LAN in the future, I have installed a pair of fiber-optic gigabit transceivers with a 3m fiber cable to isolate the cable modem from the LAN's router.  Power supplies feeding the fiber-optic transceivers are also isolated. 

I want to confirm from others that the RRC's amber Ethernet LED is normally on with a LAN connection.  It does flash momentarily at power-up but then stays out.  I just don't recall the behavior of the RRC when it was working normally but link LEDs on my other Ethernet devices stay lighted when connected.  Thanks.

I do see this in the manual:

LINK Green LED indicates link OK flashing LED indicates traffic
ACT Yellow LED indicates speed = 100Mbit/s (off = 10MBits/s)

In my case, the Green LED is blinking with data but the amber LED is off, indicating a 10 Mbps connection.  So, perhaps what I'm seeing is normal. 

Can anyone suggest a quick and easy means to completely disable the RRC audio stream when using digital modes while keeping rig control?  At my remote site, VNC is used to control digital apps on a PC desktop like WSJT-X so there's no need to stream audio.  I am on a metered 4G/LTE connection at the remote site so a very large portion of monthly data is being wasted on an audio stream that used about 50% of the time.  Ideally, it would be great to make the RRC change on the fly so that one could alternate between digital and other modes without much of a hassle.  Ideas?

General discussion forum / Verizon Wireless Drop-Outs
« on: 2018-05-09, 22:13:38 »
I am seeing a high number of Verizon 4G/LTE Wireless drop-outs.  That service is at my remote site.  I use Xfinity 100/10mbps cable modem service at home when connecting.

Ping time looks good and cell site signal strength is excellent.  Each drop out is approximately the same duration of 150 msec.  It's most problematic on CW.  It may happen a few times in a minute -- or as long as perhaps a few minutes before is reoccurs.

Any tools available to isolate this problem?

One of our remote site users is in Cancun, trying to use his RRC from a condo to connect back to the remote site in FL.  He's an experienced RRC user and routinely operates remote. 

He can obtain a solid green PWR LED connection indication, and perhaps 20% of the time he can connect to the site.  But for the most part, he cannot connect.  When he can't, the yellow LED on the RJ-45 jack flashes yellow.  The RRC manual states that this is a SIP error. 

TelMex is the cable modem ISP in Cancun.  He can ping the remote site and connect to the site's VNC and TeamViewer apps with no trouble.  Ping times are about 100 ms.

Any clues to localize a problem where the PWR LED is solid green, yet there's a flashing yellow LED SIP error?

General discussion forum / RemoteRig over Cellular Network
« on: 2016-12-15, 05:08:40 »
I need to vacate DSL and look to a cellular solution at my rural remote site.  Verizon covers my remote location with strong 4G service.  Is there a cellular data transceiver or similar that accepts a SIM card and mimics a smart phone in hotspot mode?  I am looking to use a small outdoor antenna for best reception.  The goal is to connect a RemoteRig on a small LAN to the cellular transceiver.  I am interested in specific model numbers and sellers.  Thanks.

General discussion forum / CW Mode with N1MM+
« on: 2016-10-04, 14:04:01 »
I have N1MM+ set up as a client at home.  It tunnels through the RRCs and communicates with an Elecraft K3 at the remote site.  Using keyboard CW from N1MM is fine.  But when I use paddles with N1MM running, CW is corrupt.  Without N1MM, CW with paddles is fine. 

Setup ideas?

General discussion forum / Static IP vs. DHCP
« on: 2016-04-01, 14:49:25 »
I recently changed my home router and found that my remote RRC will now only connect with the radio RRC by DHCP and not with a static IP.  Even though the remote RRC should not require port forwarding, I tried opening up the RRC static IP port and even went so far as to assign it as a DMZ port.  Still no good.  The DNS and Gateway IPs have stayed the same.  DHCP works perfectly but I would like to know why a static IP will not work on my remote RRC.

Can anyone explain this?

Feature Requests / 1216H Feature Request
« on: 2016-01-09, 04:41:02 »
1) Modify "Only one relay ON simultaneously" so that any relay can opt-out of exclusivity.   Example:  A 1216H used as a 4-square antenna switch controller where only one of four relays is allowed to be on but the 5th relay is independent and controls a switched "L" matching network to switch the array between CW and SSB portions of the band.  In this example, we want relay 5 to turn on/off regardless of the state of relays 1-4.  The present global lock-out really limits use of the 1216H web switch.

2) Add menu for adjustable time delay between switching relays when "Only one relay ON simultaneously" is enabled.  In essence, allow delay from the time a relay is turned on after waiting xxx msec. for the current relay to turn off.

General discussion forum / 1216H Switch Time
« on: 2016-01-08, 19:03:04 »
I just purchased a 1216H Webswitch and need it to emulate a rotary switch to select one of three dipoles (K8UR style) around a tower.  By emulating the rotary switch, there's a small period of time from one switch position to the next. 

At the moment, the 1216H is configured for relay exclusivity (i.e., only one relay active at a time).  However, the time period from the selection of the new relay selection appears simultaneous with the de-selection of the current relay.  What's needed is a small time delay between switching relays.  For this application, 500 msec. is adequate.  The 1216H Webswitch will control a rotary actuator that works by pulsing current through a solenoid that uses electro-mechanical indexing -- and hence the reason for the needed time delay.

Possible?  If not now, can this be added in a future F/W and web server release?

General discussion forum / Optimizing RRC CW values
« on: 2015-10-08, 17:43:12 »
I am looking for ways to optimize CW performance.  I am getting increased reports that some ops need to fill in missing information "in their heads" while copying my CW.  I have now engaged auto-space as a way to help mitigate the problem.

The control site uses fast Comcast broadband Internet service.  The remote site is limited to a marginal DSL connection.  The remote site typically has about 8 Mbps download and only 600 kbps upload.  Obviously, the upload speed is a severe limitation. 

In reading p. 93 of the RRC manual, there's a discussion of the LF DELAY and KEY DELAY values.  But I don't see a discussion on optimization or a direct relationship between those parameters, especially how to set KEY DELAY with changes in LF DELAY.  I have copied the relevant portion of the RRC manual below.

When I ping the remote site, this is my response:

Time=47ms   TTL=53
Approximate round trip times in milli-seconds:
Minimum = 46ms, Maximum = 48ms, Average = 47 ms.

So, based on this information, it appears LF DELAY should be 48ms, but what value for KEY DELAY?  Is there a network utility to measure jitter to come up with an answer that is better than an educated guess, or based on trial and error?  Tnx!

Paul, W9AC

"...The value of lf-delay depends on the latency of Internet. A good start value is
the same value as the ping time between control and radio QTH.

Another unique feature is a kind of adjustable jitter buffer at the radio end. If the Internet
connection has varying latencies, you can set a key-delay before the keying of the radio is
executed. This delay makes it possible to reconstruct the transmission on-the-fly and the
system will be much more tolerant against varying latencies (jitter). Longer key-delays give
higher tolerance against jitter but also add delay until the keying is executed at the radio.
Even if you have a good connection you could try with a low value. Remember that when you
increase this value you must also increase the lf-delay value."

I can almost never get my RRC Control unit with Wi-Fi to search/find my iPhone's Personal Hotspot connection.  Is there a trick to this?  It finds all other Wi-Fi just fine.  Mine, the neighbors, etc., just not the iPhone.  I've tried using the microbit setup program.  My other Internet appliances do find the iPhone hotspot.

The first issue to resolve is scanning and finding the iPhone on the RRC.  Later, I'll engage DHCP once it can even find it.

RRC is on current firmware 2.87.  Latest RRC hardware.
iPhone 6 running latest ios.
