I've been told that there is interest in a reverse diagram of the K3 rear panel to facilitate finding various connectors without turning the radio around. I created such a diagram for anyone

Yes, I believe the battery is just to keep the clock alive when no power is on the radio. Dale, k9vuj

According to the manual all the coin battery does is keeps the RTC (real time clock) going when the rig is powered off... 73 Stewart G3RXQ / G3Q

Martin, it's not about the battery since other changes are stored without any problems. I have two much older K3 in the shack (Ser. 17xx and 59xx) and they don't suffer from low battery. They keep

I wedge a small piece of plastic foam inside the U-shaped spring on the dot side. It serves to damp the vibrations of the contact as it makes and breaks. It may take several tries to get it right. I

The Elecraft K3S doesnt accept some semi automatic keys, the bugs. It produce real dots even when receive at his key input a short bounce, between real contacts closure, bounces barely visible on

Change the battery... 73, Martin, OK1RR Dne 19. 08. 21 v 10:02 Udo, DK5YA napsal(a):

My K3S is suffering from partial amnesia. The radio always forgets the Config: PTT settings (DTR -- RTS) after shut down. USB is set to RS232. I remember well when this has happened before to one of

I’m guessing a kilowatt and 3 stacked beams might be pointed at the “bad” neighbor? 73 Mike R 7! Absolutely Awesome

‘Dangerous’ at less than 8 feet + 6.35 inches @ 54 MHz w/ 6 db gain antenna w/100 watts, 100% duty cycle. But “dangerous” is not defined. LN

There was some comment about artifacts and k3 being held back from 100w. At this level only the 12w LPA board would be active right? 73 Mike R 7! Absolutely Awesome

This is true of Bird Wattmeters. It is NOT true of ALL wattmeters. N8LP's LP100A is specified as 5% of the reading at any power level for both power and SWR. It reads complex voltage, current, and

I have a friend who when cold on the tower used to go over to the FM broadcast antenna to warm their hands!

When specifying accuracy of a power meter, remember that the specification applies to *full scale*. So, a meter with max 100W output and 5% accuracy will have 5W accuracy with 100W. It will still have

Yep, resonance of human body is close to 6m. Mike R 7! Absolutely Awesome

Careful putting out 100 watts on 6 meters, I just did an RFI check using the new ARRL calculator and it shows how dangerous it can be for people anywhere near the antenna. But then you might already

...that's sine, not sign wave...

To measure QRP and qQRP power output I use a 2W 50 ohm terminator on my o-scope. It'll easily take 5-10W for short times and low duty cycles. With my old analog scope, I'd measure peak to peak and
