This Old Radio<\/span><\/h1>\n

Replacing memory battery in the RadioShack HTX-202 and HTX-404 Transceivers.<\/span><\/h2>\n
\n

  One of my goals when coming back to the United States was to finally upgrade my Amateur \u201cHam\u201d Radio License to Amateur Extra class.  I have been wanting to upgrade my license from a General Class license since the late 1990s.  I just could not get the advanced math in the radio theory down. <\/p>\n

   With the help of Gary Wise\u2019s (W4EEY) Amateur Extra License YouTube classes I was able to get the theory down enough to go take and pass the exam in February 2024! <\/p>\n

  Now that I was a certified Extra Class Ham Radio operator, I figured it was time to actually do some Extra Class activities, such as fixing some older radio equipment.  I have 2 old Radio Shack 2 meter, and 70cm (440MHz handheld transceivers.).  I like these radios because they actually look like radios, and are almost indestructible!  However, being so old, their mercury button type batteries that hold memory settings have long gone the way of the dodo, and produced an Er1  1 message on power-up.<\/p>\n

  Using the instructions on Craig LaBarge\u2019s (WB3GCK) blog<\/a><\/span>, I ordered the parts and a new soldering station on Amazon and set aside the time to replace the batteries in my radios. <\/p>\n
