[HamWAN PSDR] SNMP Assistance Requested

I would like to use SNMP to facilitate aiming a Node. In order to work on this project, I have setup a Node (LHG XL HP5) and Sector (5SHPn) for testing purposes.

The following shows the status of my Node:

[herbw at AA7HW-01] > /snmp print 
          enabled: yes
          contact: #HamWAN-Support on irc.freenode.org
         location: 45.489139,-122.631972
   trap-community: hamwan
     trap-version: 1
  trap-generators: temp-exception
[herbw at AA7HW-01] > /interface wireless print oid
 0 tx-rate=. 
 [herbw at AA7HW-01] > /interface wireless scan 0
Flags: A - active, P - privacy, R - routeros-network, N - nstreme, T - tdma, W - wds, B - bridge 
       ADDRESS           SSID          CHANNEL        SIG   NF SNR RADIO-NAME        ROUTEROS-VERSION       
A RT B 4C:5E:0C:89:3F:57 HamWAN        5880/5/an      -28 -124  96 K7ICY-Tolliver   
-- [Q quit|D dump|C-z pause]

Based upon the above, I would assume that if I query the signal strength (. using snmpget, I would obtain a value of approximately -28 (the signal strength varies a bit from the instantaneous value of -28 reported above). However, although I am able to obtain the SSID using snmpget, I am unable to obtain the signal strength, frequency or band:

$ snmpget -c hamwan .
SNMPv2-SMI::enterprises.14988. = INTEGER: 1
$ $ snmpget -c hamwan .
SNMPv2-SMI::enterprises.14988. = STRING: "HamWAN"
$ snmpget -c hamwan .
SNMPv2-SMI::enterprises.14988. = INTEGER: 0
$ snmpget -c hamwan . 
SNMPv2-SMI::enterprises.14988. = ""

Also, is it possible to obtain the Noise Floor (NF), Signal to Noise Ratio (SNR), or Radio Name from my Node using SNMP? These are all reported by the /interface wireless scan 0.

Thanks for any assistance you can provide.

Herb, AA7HW
