Keyers are very different. For example, I am a mode B guy and a 'squeezer', but I find mode B on the Logikey, the K3 and the WinKeyer have different timing demands. I have beaten myself into being able to use the K3 keyer despite formerly using the Logikey, but I had to make a conscious effort

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

The TMP connectors are not that hard to insert, but the danger is that it is easy to apply too much force when they are not aligned properly, and damage the socket-board connection. You can lift the trace from the board if you are not careful (yes, I learned this the hard way). The trick is

Re: [Elecraft] K3 Popping noise in headphones??

Well, I have an old K3 plus new synths, I have the RX EQ set to zero dB all across its range, and I hear the noises. I would call them short tone bursts rather than pops, though. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 18 Oct 2015 21:16, Joe Subich, W4TV wrote: On

Re: [Elecraft] Unplugging the radio to protect it

Very few hams, if any, disconnect EVERY cable from their rig when it is not in use. Having said that, it's certainly a good idea to have a common grounded entry point with suppression devices for power, antenna, phone, cable, etc. so there won't be potential differences between equipment in

Re: [Elecraft] PC<>P3

Salvo, I don't have an Ultrabeam, but I have an older Palstar AT-AUTO antenna tuner hooked up like this. I have simply paralleled the RS232 RXD input to the tuner with the TXD line from the P3 that goes to the computer. I did not connect the TXD line of the tuner. The tuner is in a

Re: [Elecraft] K3S proper grounding?

The problem has nothing to do with grounding. RF is getting into the house wiring. I suggest adding a choke balun at the feedpoint of the antenna to reduce "RF in the shack" and wrapping the power cord of the TV around a ferrite rod, toroid or bead for several turns. Google K9YC's RFI

[Elecraft] Palstar AT-AUTO with K3

I have an opportunity to get a Palstar automatic tuner, the AT-AUTO. This is an older version, NOT the new HF-AUTO. It has an RS232 interface which the manual says can be used in a listen-only configuration with transceivers that send frequency data from a CAT port. It does support the

Re: [Elecraft] K2 Options

I had both but ended up keeping the audio filter. I think it's a matter of personal taste, so if you have the opportunity to try a K2 with those options, it's worthwhile. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 7 Sep 2015 06:45, Dauer, Edward wrote: Still exploring

Re: [Elecraft] K3S SubRx Question

Both receivers are muted on transmit regardless of the antenna connections. The carrier operated relay will protect the receiver (or not), but it doesn't have any effect on what you hear. Don't know about the schematic. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 27 Aug

Re: [Elecraft] Features wanted

You can adjust the frequency of the APF peak with the SHIFT encoder. You can also tap the FINE button to get a slower tuning rate when you are using the APF. This makes it a bit easier. In some conditions the APF makes the difference between being able to copy a station and not. Its

Re: [Elecraft] Diversity Reception

I use diversity (vertically and horizontally polarized antennas) on CW a lot, and there's more to it than just selecting the louder signal. I can't put my finger on the precise mechanism, but it seems that CW characters are less prone to being damaged by bursts of QRN in diversity mode. 73,

Re: [Elecraft] Linked VFO's -- usage?

What I do is switch antenna connections. My secondary antenna is connected to both the RX ANT and the sub's BNC input. So I can listen to the main + secondary antennas in diversity mode, just the main antenna with diversity off, or just the secondary antenna (regardless of whether diversity

Re: [Elecraft] K3: 630m amplifiers

A CW amplifier can be designed to run class-C but to be keyed in such a way as to pass through the linear portion of the amplifying device's curve when a CW element is starting or ending, in order to preserve the shaping. A simple example is the tube-type amplifier that has just enough fixed

Re: [Elecraft] Another one of those filter questions

You are correct that the offset is zero for 8-pole filters. What I do is adjust the filter gains so that there will be no change in signal strength when switching filters. You can do this by ear if you turn off the AGC, or you can use the K3's DBV function if you are a perfectionist. I
