Operate an amateur radio station from anywhere with an Internet connection.

14 – 16 September 2021 Status – WA0TDA & W0ZSW online, W0EQO online


W0EQO Update:  Station W0EQO is now in Park Rapids.  It is operating at 60 watts due to a problem with RF in the shack.  Digital mode operation is NOT allowed as this is likely to trigger the RF problem and cause a loss of internet control.  SSB/CW should be okay.  We are considering ways to address the RF problem.  It is worst on 40 m, so no 40 meter operations are allowed at this time.

Both Twin Cities stations are subject to intermittent outages because of thunderstorm activity.  Antennas will be disconnected to protect the equipment.

    1. New RCForb software

Thunderstorm season has returned to Minnesota.  There will be sporadic outages at WA0TDA & W0ZSW as the antennas will be disconnected to prevent lightning damage to the stations.   You can check out the lightning map at: https://www.blitzortung.org/en/live_lightning_maps.php?map=30

Once the danger of lightning is past, the stations will be returned to service.  

Use the latest version 0.9x software or it will not work on Windows!  Download the new client software to use the remotes here.

The quick start guide is for anyone who wants to install and use the RCFORB HF remote base client software from Remotehams.com with a minimum of time and effort. That would be most of us! A quick start guide shouldn’t be
wordy, so let’s just use some simple steps to get you up and running.

IMPORTANT:  Register with Remotehams.com using YOUR CALLSIGN as the username, or this will not work!

Choose ONLY 0.9 software!

I have made two YouTube videos on the use of the RCForb software.  This one
is for the free Windows version:

Software radio interface now includes POWER button on W0ZSW

The POWER button on version 0.9x of RCForb software

The POWER button has been activated on the W0ZSW station interface in version 0.9x of the RCForb software. Please turn the IC-7300 power off when you are finished using the station.

The W0ZSW radio, an Icom IC-7300, supports power on/off while maintaining handshaking with the host PC, so we have added the optional POWER button to the client software interface.  Please use the POWER button to turn the radio on when you begin a session and off when you are finished.

WA0TDA recovered from Sunday morning outage


Mini PC: Host computer for WA0TDA HF remote

The WA0TDA IC-7200 is back online following a multihour outage caused by Windows Update.   The update began in the background on the host PC, at first leaving the station accessible at login, but unresponsive to control.  I have seen this in the past and knew that the station would no longer work correctly without manually completing the pending update.  This is simple – just approve the update by selecting “update & restart” from the power button, then manually restarting the RCForb host software.

This was completed, and at first seemed to be okay, but after a few minutes of operation, the station lost connectivity due to ports closing on the network.  Killing and restarting the RCForb software fixed that, but all told the station was offline longer than expected.

Everything was working as of 10:00 AM CST.


USA License Required for Operation of USA-Based Remotes

Pat, WA0TDA, wearing headset and holding licensing manuals.

From time to time I get requests for station transmit privileges from operators outside the United States and its territories.  It doesn’t matter where the control operator is located,  but there is a USA requirement that the control operator must hold an FCC-issued Amateur Radio License with the appropriate privileges.

For more information on the requirements, please follow this link to the ARRL website, which does a great job of explaining it and answering your questions.


W0ZSW & WA0TDA back online following maintenence

Both W0ZSW and WA0TDA are back online following Windows Update on both station host computers.  When updates are loading in the background, sometimes things don’t work properly; the antenna tuner might not function, the sound may not work correctly, and some other functions seem slow or don’t work at all.  Please let me know if this happens so that I can address the problem as soon as possible.

Short-term outages may also occur when the Eero mesh network used for internet routing at this location performs an automatic update.  These are unscheduled but seldom last more than a few minutes and the stations will generally be up and running without further intervention.

You may contact me at my callsign at ARRL.net if you notice any issues.

W0ZSW offline due to radio encoder failure

The VFO encoder on the W0ZSW IC-7200 has failed.  Although the VFO can of course be controlled by the remote software, unfortunately this is NOT the case with the audio input mode, which depends on the VFO encoder to “choose” the necessary USB input instead of MIC.  When the radio gets stuck in MIC mode, no audio can be transmitted.  Thus, except for CW operation, the radio is only useful as a receiver.

The only options at this point are to use the station as a CW only one or to go off the air until a replacement is found or a repair can be made.

At this time the station is off the air.
