Jim, Don't get me wrong, I am quite happy using UHF to BNC adapters where they are convenient. I use PL-259 connectors on RG-8X or RG-213 cables for my intra-shack connections. In other words, I use what works. I do have several cables with PL-259 on one end and BNC on the other to connect to my QRP gear. I have no desire convert my equipment from the connectors that are standard for that piece of equipment to anything else. There are adapters and "tween series" connectors that will serve as the transition pieces.
As A "for-instance", my HW101 used an RCA jack for the RF connector (the Collins KWM@ and S-line did too if my memory is correct). The use of an RCA to either BNC or PL-259 adapter is prudent rather than changing the connector on that piece of classic gear. 73, Don W3FPR On 4/24/2012 10:13 PM, Jim Rhodes wrote: > I had Joel at The RF Connection (therfc.com) order me some BNC panel > connectors with the same bolt pattern as an SO239.
