XW4ZW will be QRV December 3 - 8, 2017 with focus on the lowbands. 

Thanks to Lee, K7TJR and Hi-Z Antennas, we will have a brand new Hi-Z 4-8 Pro vertical RX array to use. It will complement the south beverage.  

While we have some very effective receive antennas at a QTH far outside of the city, a problem still exists where I am being heard better than I am hearing stations calling me.  It's very frustrating and somewhat embarassing, hearing from people how loud I am and that they have been calling sometimes for 30 minutes or more.  To be sure, we're fighting an uphill battle with poor band conditions.  I spoke to noted propagation expert Carl Luetzelschwab K9LA about this, to see if there might be more going on.  Is there such a thing as one-way propagation?

K9LA and W3LPL did a wonderful Webinar on propagation for the upcoming 2017/2018 season which is posted at:

The entire Webinar is worth watching, but Karl addresses challenges on lowband paths between the US and XW starting at 32:30 in the recording.  Some interesting food for thought. 


Please no dupes!  If we have worked before, please do not call again, as tempting as it may be.  Give others a chance. 

QSL options:

via K1SE with SAE/SASE - NO IRC's

PayPal to e-mail address on this page (include QSO information and mailing address for the card).  $2 USD minimum.  Additional support greatly appreciated. 


Bureau Cards - All bureau cards received will be answered but it is time consuming and expensive.  Please note that I receive cards from the bureau on average once or twice per year.  It takes up to 1 year to answer the cards.  You will need to be patient.    

A log checking tool is below, after the pictures.
