The choke used in the '830 line (and a number of other Kenwood rigs) in P/N L15-0016-05. No data appears about this part online, though it's available to order from PacParts. I dug into my junk box and found a few chokes of the same form factor; these had been salvaged from CB sets over the years. Using the LCR bridge with a 120Hz test signal, I inspected the lot. Of them, I selected an 8mHy part; it had a measured Q of 3.6. The windings look to be good for 2-3A, which jives with an SSB CB's power requirements.
