Re: [Elecraft] [K3] [P3] IF Out / IF In Cable
Wrong use of 75/50 ohm cables is a cause of unreliability on scopes: they're made for 75ohm connectors and if you plug in a 50ohm plug is will eventually splay the centre contact and cause intermittency.

Re: [Elecraft] [K3] [P3] IF Out / IF In Cable
There seems to be confusion over 50/75 ohm connector mechanical compatibility. 50 and 75 ohm N connectors are not mechanically compatible as the center pins are different diameter--50 ohm has larger pin diameter. Over time, a 50 ohm N male connector can damage the 50 ohm female N and a 75 ohm N male may not make reliable contact with the 75 ohm female N. However, everything I can find in terms of published dimensions, specifications and measured diameters says that BNC pins are of identical diameter in 50 and 75 ohm variants. The difference in impedance seems to be handled in the dielectric dimensions and material. Many HP 75 ohm BNC connectors, for example, have no plastic dielectric at all in the female version--the center socket fingers have nothing supporting them but air. It may be that in ye olde days of the early 1940's when the BNC was invented pin diameters differed, but if that was the case then, it seems to have vanished in the last few decades.

Yes there is a difference.

Well, to throw you all out of whack, I used the 93ohm cable. There is no dielectric between the pin and shield. My micrometer will not get in that space very well, but it appears that the diameter is ~1.20mm. I have not noticed any squirrely problems so I'll keep it there for now.

The cable you reference is built with RG59 (75 ohm) which should put to bed the question of whether the application must use 50 ohm.

There are times when 75 ohm cable is preferred, regardless of the rated load impedance of the rig or power amp. A high dipole (as a fraction of a wavelength) is a closer match to 75 ohm cable than to 50 ohm cable. Excess loss in the coax due to mismatch is determined by the match between the antenna and the line, NOT between the rig and the coax, although some matching may be required at the rig to keep the output stage happy and transfer full power to the load. In addition, because the current in 75 ohm coax is one third lower for the same transmit power as in 50 ohm coax, 75 ohm coax of equivalent size and construction typically has a bit less loss than 50 ohm coax. The 80/75M band has a bandwidth of nearly 10%, so 75 ohm coax provides lower SWR on a high dipole over a greater bandwidth. Yes, it's wise to be aware of cable impedance so that we're not generating mismatches by inserting cable of the wrong impedance, but don't throw the baby out with the bathwater. :) I use mostly 50 ohm coax, but have at least 300 ft of Belden 8213 feeding my two high 80/40 dipoles, and several resonant lengths of CATV hard line feeding my 20M and 15M yagis. There are also some really neat broadband matching tricks that one can play with resonant lengths of 75 ohm cable. I'll be talking about that at Pacificon Antenna Forum next month. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] [K3] [P3] IF Out / IF In Cable
