Update: W0EQO transmit button change test

W0EQO test: The TX transmit button had been removed and replaced by the Txd button.  This affects primarily Windows app users.  Android app users used the PTT button as usual.

The Tune button had been added in order to make this function work on the Android app.  It activates the antenna tuner briefly, which allows a previously stored antenna tuning memory to be selected.  For a longer antenna tuning, use the Txt button, which allows more time for the SWR to drop down to its minimum at the displayed frequency.

Results:  Users reported that audio was not transmitted over the air, although it was loud & clear in “test” mode (VoIP talkaround).  As of now, we have had to restore the TX transmit button, which restored the audio out over the air.  Further tests pending.

Please report any problems to admin at wa0tda@arrl.net.

W0ZSW returns to service after antenna change

 

The W0ZSW station with IC-7300 & LDG tuner

W0ZSW was offline for antenna maintenance and host PC updates.  It has returned to service with an inverted vee maypole antenna and has been tested on 160, 80, 40, and 20 meters. Antenna tuning may take longer than usual on frequencies that the LDG AT-1000 PRO tuner has not already memorized. Frequencies that it “knows” will tune almost instantly. Please let me know if you run into any problems with antenna tuning.

The old antenna system will be taken down soon and reconfigured later this summer.  It had suffered decreased performance after it had to be partially taken down and moved for tree trimming last year. Plagued by a high noise level, it was clearly underperforming on receive and would need to be relocated.  There is no particular timeline for this project, nor have I decided on exactly what will replace it.  However, the inverted vee maypole, formerly service the WA0TDA remote, is working very well and is much less noise-prone because it is well away from the house, fed with buried coax.  Users should notice quite an improvement.

The WA0TDA remote is still on the air with an enhanced Butternut HF9V vertical antenna, ground mounted with buried radials and fed with underground hard line. It is also an excellent antenna system, but users will notice the different characteristics of a vertical antenna.

Unfortunately, this means I have no antenna for my IC-706M2G digital station at the moment.

March 29 – First thunderstorm outage of the season

Stations WA0TDA & W0ZSW went offline late in the day on March 28 and remained out of service on the morning of Sunday, March 29.  This was an orderly shutdown to preserve the station hardware from lightning damage as thunderstorms moved through Minnesota.  Lightning strikes were detected within 1.3 miles of the stations.

Both stations will return to service before 9:00 AM CDT Sunday, by which time the antennas will have been reconnected and the systems rebooted.

This is a good time to remind users that shutdowns for thunderstorms may occur without notice now that the season has started.
