Next weekend [September 7-8, 2019] we have a QSL Bureau booth at the HamXposition/Boxboro show. Our booth will be next to the ARRL booth.
You can fund your Bureau account and get answers to your questions about the Bureau.
We will be accepting cards for the ARRL Outgoing Bureau at the booth. Please see the instructions on the ARRL web for sending your cards and the fee structures.
There is also a simple form to submit with your cards found on the ARRL web. Fee payments can be done by check or exact change cash.
We are just collecting the cards for the ARRL so please give them to us with the funds etc. as if you were mailing them to Newington.
Also, we will be hosting the DXCC card checkers. You will need to do the application process online before the show. There will be a checker at the booth Saturday from about 11 AM to 3 PM and all morning Sunday. You can also leave cards with us for checking when the Card Checkers are not there. You can authorize someone to pick them up for you or work with me for another way to get them back to you
