The Micro Engineering Labs Web site referenced in "A CTCSS Tone Encoder with Morse Code Readout" [July 2004, p 34] should be www.melabs.com.

In the Product Review column, "Ameritron ALS-600S HF Power Amplifier with Switching Power Supply" [March 2005, pp 60-62], we inadvertently listed an old ALS-600 power output specification for CW. The current specification is 500 W output on CW, not 400 W as listed. The amplifier more than met the new specification.

My March 2005 article ["A Backpacker's Delight--The Folding J-Pole, pp 31-33] should have specified 5 feet of 3/16 inch OD bungee cord, and not 5/16 inch.--Mike Heiler, KA0ZLG

In the Figure 2 parts list on page 28 of my article, "A Miniature UHF Fox Transmitter" [March 2005], the correct Jameco part number for the battery holder is 216186.--Dave Bowker, K1FK
