1231AG - RM21A - Wireless A Transceiver not Broadcasting
A Cisco 1231AG AP has been used for quite awhile with, 802.11b/g only for a few years. The RM21A module was purchased and installed. The module is recognized and the radio interface is visible in the config. The goal was to have the same SSID on the 802.11b/g antenna as the 802.11a antenna. I used a wireless tool "Wifi Analyzer" on my phone to verify that it doesn't see the channel.
Below is my current config, with extraneous pieces removed. Any help would be greatly appreciated. Thanks you all in advance.

Thank you for responding. My phone does have an 802.11a receiver. I can see SSIDs from other APs on it.
Below is the output from: show ip int br.

Also, the tool looks like if an SSID is broadcasting it will pick it up. In addition, if the SSID is already programmed into the phone it will pick it up. Please see the photo below for what it looks like. From what I see (look at the top for a view of the work 802.11a spectrum) it is clean.
