Mike, Good work to have discovered where the problem lies. You might want to obtain a new KNB3 board and simply replace the one in the mainRX. Yes, you can swap the KNB3 between the main and the sub, so if you want --- Look in the K3 assembly manual as well as the KRX3 manual to see where

Re: [Elecraft] K3 NB

Mike, They can be swapped. You need to take out the second receiver to get to the one on the main rf board. One screw takes each one out. Make sure on the rf board that there are two lockwashers between the NB standoff and the rf board. Take the screw out and the bard pulls out. Swap them and put

Well Ron, I guess there's a first time for everything. Although the radio was deaf and dumb, I had display function and it looked as it normally does after turning on the power. There was just no receive nor output power. I turned it off, pressed the 20 amp circuit breaker on the rear panel

Re: [Elecraft] K3 NB

Mike, Yes, the KNB3's can be swapped. But if you'll be in there anyway, I'd strongly suggest that you first remove and then re-insert the KNB3 module in your main receiver first. Then try it out and see if the blinking "NB" issue persists. If not, you're done. Otherwise, swapping them and

Re: [Elecraft] K3 NB

Noise blankers have never worked well, or at all, on most power line noise which is usually caused by very small arcing in the distribution line [usually around 12 KV in the US] hardware on the poles. It's multiple arcs, and the noise pulses from each one overlap each other producing the

Re: [Elecraft] circuit breaker

Todd responded to me off the reflector that he lost all power to the K3 so it wasn’t the 20A breaker. That only controls power to the KPA3. The front panel is still powered and the receiver continues to work. I suggested it might be the self-resetting breaker inside the K3. That will turn

Re: [Elecraft] circuit breaker

I believe Todd is referring to the breaker on the K3, not his house panel circuit?Ron has some good advice, but I wonder how common this circuit breaker operates?  I looked thru my manual for more info on it.  The block diagram shows it as a 25A fuse,text and device indicate 20A circuit

Re: [Elecraft] circuit breaker

The normal underlying cause for the breaker to open is over-current. That's a 20A breaker that protects only the KPA3 100 watt amplifier module. The first thing I'd do is check the current drain from your power supply on the band where you experienced the problem. First set the power to 10 watts

Re: [Elecraft] circuit breaker

Check if the breaker is an AFCI type breaker. If it is there is an article on the ARRL site with details on how you might get them replaced for free. I just went through this with mine. Homes built after 2011 have arc fault tolerant (AFCI) breakers. The RF can cause them to open. I contacted

Re: [Elecraft] [K2] External amplifier keying circuit question

Steve, It is not a good idea to leave the gate of a MOSFET with no static drain on it. When the board is removed from the K2 the gate at the input is exposed - thus the 100k The 100k between the 2 devices might be omitted if you wish. The first link you mentioned is Eric Swartz work - the

Would anyone venture to guess what would cause the circuit breaker to trip on a K3? Mine did all of a sudden yesterday. Fortunately, my friend suggested the reset and voila, I am back on the air. But if there is an underlying cause, I think it would be wise to be aware of it so as to preclude

The easiest way I've found to reroute signal lines in these sorts of cables is to build a little "adapter" of back-to-back DB shells (9, 15, 25), one male and one female, separated by a pair of 1" 4-40 hex standoffs. You then wire between the shells whatever pinout changes you need.
