NOTICE: In July 2021 the channel name changed from HamCuredSmoke
To Ham Radio A2Z. All of the earlier videos (like this one) are still available.


In this video we're going to build an external keypad to access the transmit memories on the 7300. This will work for the voice, CW or RTTY transmit memories.

Below are the parts that I ordered to build the box (Note: These are affiliate links):

Pushbutton Switches: amzn.to/39XMqYV

Microphone plugs & jacks: amzn.to/39SrG4Q

Project Box: amzn.to/3wFOmPy
( I bought the 3.94" x 2.68" - you might want to go up one size to the 4.5" x 3.5")

Resistor assortment: amzn.to/3fV1SZx
(NOTE: This is way way way more than you need unless you're building up your project parts bins. However, it does include the values that you need and it was only $13 at the time I ordered it)

These are not affiliate links, but you should be able to get the resistors and most of the other parts at Mouser or Digi-Key:
