CAVEAT EMPTOR: Chinese soldering flux ZJ-18
Many sellers from China/Hong Kong offering on eBay a "solder flux" which is of very bad quality.
What is behind the Hi-Tech look of the ZACH Iambic Magnetic paddle?
Many friends asking me to comment the new ZACH Iambic Magnetic paddle which I am now using. So, my trusty N2DAN Mercury has now a longer vacation and the new ZACH became my daily-paddle. It is very easy to adjust, much easier then the Merc. And once adjusted, I can forget what, where and why...

The bad thing is I keep getting older...

Getting older is the best of all the other options.
Notes on call/QRP
Many well respected operators offered their opinions on call/QRP. It is considered sometimes as trying to gain unfair advantage, sometimes as deliberate altering of an official callsign but the majority considered it as counter-productive practice hurting both the user and his QSO partner. There is a significant number of high-profile DXpeditioners and contesters avoiding working, logging and QSLing call/QRP users.
Farewell Collins Mechanical Filters
FILTERED OUT FOREVER
For many radio amateurs, it’s the end of an era: Rockwell Collins, which designed and manufactured mechanical filters for more than two generations of hams, has discontinued the filters’ production.
The company posted on its website: “Over the past several years, we have seen a dramatic reduction in demand for narrowband analog filters. Due to this and other economic reasons, Filter Products will be discontinuing its mechanical filter products in the near future.”
The company acknowledged that the filters have since been eclipsed by digital signal processing, and this was a significant factor in its decision. Highly popular mainstays for many hams, the mechanical filters were valued for being able to achieve bandwidths of between 0.05 percent and 5 percent, with input and output transducers converting the electrical signal to and from mechanical vibrations. Rockwell Collins has not yet announced a date for the final production run.

QSL Bureau - a big shame?
[DXNL 1821 - February 27th, 2013]: Changes in the USKA QSL bureau:
QSL cards for non-members of the Swiss IARU society USKA will no longer be returned with a "Not Member" stamp, but silently discarded, to save work and money.
What a shame! This is known problem for many years: the QSL Bureau is roughly abused by a national Ham Radio Society (mostly IARU member) to force hams in the country to join. On the other hand, the Ham radio society officers whining about declining ham-spirit and operating skils. Isn't something rotten there with the IARU and ham radio generally? Why a QSL Bureau can't serve at non-profit basis for an acceptably small fee to ALL HAMS IN THE COUNTRY, regardless of membership?
A particular ham may have a half dozen of reasons to NOT be A MEMBER of the local Ham Radio Society but such ham is excluded from the common QSL exchange. This is an usual practice in many countries for years.
Anyway, my QSL card is MY PROPERTY until delivery to the recipient. I pay for a QSL card (printing, labels, my postal or QSL Bureau expenses etc.) in good belief that it will be delivered to the recipient. The Ham Radio Society decides to silently discard my property without informing me about my waste money.
How much QSL cards discarded do I need to initiate a lawsuit to get a compensation? Where should I get a proof that they actually made such nasty act?
WE NEED A CHANGE!
