Re: [Elecraft] XV50 no output

And it turned out to be the cable from the K2 to the transverter. The pin of the BNC plug at the XV50 end had pushed back so not making. Together with the BNC/phone adaptor at the K2 end which is not the best arrangement. I obviously need to make up a couple of proper phono-BNC cables. I

Hi Dave, and to the masses of readers we can hear breathing in the background... I've surely done that myself, once with the equipment out and ready to ship before logic gained the upper hand and I started checking cords and connectors, finally detecting a male BNC on a cord with a retracted

Re: [Elecraft] XV50 no output

Danny Decent BNC connectors have identical pin diameters in both 75 and 50 ohms versions and are fully compatible (unlike N type which are definitely incompatible). But obviously these cheaper ready made up cables use cheap plugs so may well have fat pins. As an interim measure I have taken a

Re: [Elecraft] XV50 no output

Dave, Properly tightened against the internal tooth lockwashers, those RCA jacks should not loosen. Unless someone used substitutes, they have a hex nut on each side of the panel and an internal tooth lockwasher on each side of the panel too. Use wrenches (spanners for you) or pliers and

Re: [Elecraft] XV50 no output

You must have had some older 75 ohm BNC connectors. Those which comply with the 1978 standard IEC 169-8 will interchange non-destructively - so says Wikipedia 73, Don W3FPR On 11/21/2015 2:44 PM, Danny Higgins wrote: I remember buying some cheap BNC patch leads at a rally which worked fine.

Re: [Elecraft] XV50 no output

Thanks Don. Having looked at it again it does actually look as if the output from the K2 transverter socket is missing or very low. I got a bit confused about levels (as well as making typos) and I should most definitely be able to see the 1mW on my scope (632mV p-p). I did have to tighten up

[Elecraft] XV50 no output

My XV50, which worked fine for this summer's sporadic E season, has suddenly gone faulty and has no output in either CW or SSB. The input from the K2 is present, although of course 5mW is pretty hard to measure accurately with my scope. There is also no signal at the input of the power

Re: [Elecraft] XV50 no output

Dave, Be cautious with conclusions when probing with a 'scope probe in the 50 MHz section of the XV50. The probe can pick up RF and produce false output indications. The fact that you can induce output by probing C48 does normally indicate that U6 and U7 are capable of producing a signal.
