NASA Soldering Instructions

An Oggie who wishes to remain unnamed sent me this extract from NASA soldering guidance circa the Apollo moon project. The big difference between normal techniques and this one is that NASA recommends clipping the leads prior to soldering. It makes for interesting reading.

Unlock Key Code for Anytone AT-D878UV

I received an email to Ask Dave inquiring about the key sequence to unlock the keyboard. The radios come from the manufacturer with the keyboard locked so that it complies with FCC rules for those outside ham radio who are not allowed to program their own radios. Hams, however, are permitted to program their own radios.

The instructions are found on Page 38 in the manual. You press the Menu and Star keys together. Here is the relevant extract from the manual.

Extract from Anytone D878UV manual describing how to unlock the keypad. First, press and hold the Menu Key. While holding the Menu key down, press the star key. This should unlock the keyboard.

As far as I can tell (and I could easily be wrong about this), once the programming is unlocked the radio stays unlocked.

Announcement: Tech Videos (4th Edition) Now Available on Thumb Drive

The Technician training videos on YouTube are now updated for the 4th edition of the ARRL Ham Radio License Manual. In addition, by popular demand, I make them available on a USB Thumb Drive for US$29.99, postpaid anywhere in the United States. See here for details.

This is good news for those who can’t always get online to study, such as those with poor Internet connectivity, commuting on trains or busses, etc. This thumb drive with all the videos would also make a great gift for those of your friends or family who would make great hams once they get their license!

You are welcome to use the videos during club meetings or for training classes. See the details on the purchase page.

Log Stamp Images

In Ask Dave 18, I showed a rubber stamp that I use to create an entry in an ordinary notebook for logging. Gwen Patton, N3GP, has recreated the image of the log stamp for anyone who’d like to recreate the stamp for their own use. Here is the image:

Clear image of my logging stamp for use with any notebook. Thanks Gwen Patton, NG3P.

Here’s the rubber stamp I had made at a local stationery store, sitting on an American 3″ x 5″ card for size comparison.
