There is a fantastic upgrade that makes the Lanch HG-UV98 more than 30% better, according to members of the HG-UV98 Users Groups.io community. We have Kenny KT2KT to thank for this "surely" good to "OK" great upgrade among other things.
If you are in the market for a low cost and rugged dual band APRS radio, this radio is proof that community can improve on what a vendor offers by modifying its software, just like we have seen by the TYT MD-380, Radioddity GD-77, Baofeng DM-1801, Anytone AT-878UV and Alinco DJ-MD5 series of radios.
Who says hardware is the only thing worth modifying!
One of the most easy to point out differences with Kenny's firmware update is the change of the main menu button from using the word "Sure" to "OK".
Other big changes involve improvements for certain menu description such as the dual band display menu that now shows single or dual instead of words that made no sense plus improvements in the APRS and other function menus.
How To Update
You will need good terminal software such as the free TeraTerm or Hyper Terminal applications to upload Kenny's modified firmware to your radio. His version is based on the latest official release by the manufacturer available as of the date of this article.
If you are a Linux vagrant rather than a Microsoft follower, you will likely understand how to take these instructions and get things to work on your computer to do the upgrade. Apple hamsters will just need to figure things out on your own.
Go ahead and press the "1" button on your keyboard and your terminal will now wait for you to upload the new firmware. Go ahead and go to "Transfer" and click on "Send File" in Hyper Terminal software.
