Where’s My WAZ Certificate?
Guess what! Today, I received (by postal service) this very nice plaque from CQ, for working and confirming all 40 of the worldwide CQ DX Zones.
CQ WAZ NW7US – Mixed – Plaque
Many of you wonder, “where are my paper certificates for my WAZ efforts?”
At least one, if not all of the following, are reasons why there has been such a long delay in getting paper certificates for the WAZ CQ program:
- Paper certificates (blanks) were not available and backordered (Covid, folks).
- There is only ONE person doing the lettering (by hand).
- The advent of FT8 and FT4 in the WAZ program has SWAMPED the program. There’s a HUGE backlog.
That said, the new CQ WAZ Manager (N4BAA, JOSE CASTILLO) has made the following statement available:
— quote follows —
Effective September 1, 2022, CQ Magazine will no longer provide the Hand Lettered CQ WAZ paper certificate for free.
CQ WAZ AWARD RECIPIENTS HAVE 4 AWARD OPTIONS:
- Accept the standard award offering which is a High-Definition PDF file. This file can be printed in color and framed and is very nice. This award is delivered immediately with award letter, thus, no waiting.
- Select the traditional CQ WAZ Hand-Lettered award: the cost is $19.00 and includes shipping worldwide. This award option is managed by CQ Magazine and can take up to 180 days to receive.
- Select a Level I plaque: 7” x 9” two-tone engraved wood plaque: cost is $57 US / $100 International and includes shipping. Delivery time is under 30 days for US stations and less than 60 days internationally.
- Select a Level II plaque: 9” x 12” Floating Etched Acrylic over Black Wood: cost is $91 US / $135 International. and includes shipping.
Here is a video that the administrator has posted, about this:
[embedyt] https://www.youtube.com/watch?v=JFJBbZ0yb3c[/embedyt]
Delivery time is roughly 30 days for US stations and less than 60 days internationally depending on the actual address.
The intent of this program is to respond to the ever-increasing demand for more options that are still very personalized as well as very elegant.
Not every ham is able to achieve the requirements for a 5BWAZ or 160 Meter plaque, so he is making this offering to everyone!
All questions or inquiries and plaque orders should be directed to the CQ WAZ Manager via email at [email protected] or postal mail via QRZ.com address.
All plaque data will be taken directly from the information provided in your email. The CQ WAZ manager will not be responsible for errors in data supplied by the recipient other than AWARD type and Award number.
To Place Order: send the information below via email to [email protected] or via postal mail to my QRZ.com address and please double-check spelling etc.
Email Subject line should be: “WAZ PLAQUE ORDER – YOUR CALL”
Then, provide the following information:
Call Sign:
Desired Name on Plaque:
WAZ AWARD Type
(example: MIXED, RTTY, 15M CW, EME, etc.)
SERIAL NUMBER on award:
Date on Award:
Award Desired:
– Level 1 plaque – $57 US / $100 International
– Level 2 plaque – $91 US / $135 International
There you have it…
