Many thanks to SWLing Post contributor, Markku Koskinen, who shares the following:
Just letting you know that Icom has released new firmware for the IC-R30 receiver.
Please read carefully and follow all instructions:
https://www.icomjapan.com/support/firmware_driver/
Changes from version 1.10: Fixed the problem of when the ANL of the band that is not used is ON, while the Dualwatch function is OFF, the received DCR audio may not be output from the speaker.
This firmware is for the USA version that has a serial number beginning with “16”.
This firmware is for non-USA versions that have a serial number beginning with other than “16”.
Thank you for the tip, Markku!
Loaded it with no problems!
As a side issue, purchased a Sangean ATS-909X from ebay for $206.20 from the same seller that is currently listing it on Amazon for $219.18.
The pricing on this receiver appears to jump all over the place!
