Re: [Elecraft] K3 FD report in high RF (K3 vs Flex 6xxx)

A couple of years ago I asked W1RFI at Visalia how come they would include a picture of a very sharp keying waveform and a spectrum display showing loud clicks or phase noise but not interpret it for the less technical types. He said that if you want that you should write to the editor of QST

Re: [Elecraft] Frequency Limits by license?

It wouldn't be a good idea to depend on the transceiver. If you are operating USB, for example, you have to keep the (suppressed) carrier frequency several kHz below the top of the band so your sideband will be inside it; same for LSB and the bottom of the band. Even in CW there is a

Re: [Elecraft] K2 with rigblaster

K9YC's grounding and choking methods are one part of the solution. The other is reducing the amount of RF flowing on your station equipment. Off-center fed antennas and verticals often produce common-mode currents on feed lines. Changing the feed line length away from odd multiples of 1/4

Perhaps it was 3-phase hum? The really big amps run on 400V 3-phase circuits (no, Elecraft won't be making these)! Vic 4X6GP/K2VCO On Jun 6, 2015, at 12:54 AM, Oliver Dröse dro...@necg.de wrote: Hi Gernot, as I am hearing lots of similar signals from a few of the very very big guns

Re: [Elecraft] CQ WPX and the KSYN3A board?

You really need to do an a/b comparison, which of course I didn't do. I also just added a set of 5-pole 200 Hz filters. But subjectively my K3 felt more comfortable than ever among the big 1-hop signals from EU that I experience. I found myself working closer than ever to strong signals. For

Re: [Elecraft] K3 TX DELAY

Agreed. With a K3 you don't need any special sequencing -- just replace the relay with a reed relay for input and a vacuum relay for output (or two vacuum relays). It is much more pleasant even if you don't use QSK or VOX. Vic 4X6GP/K2VCO On May 31, 2015, at 7:21 AM, Guy Olinger K2AV

Re: [Elecraft] KX3 and PX3 with 2m Transverter comments

I don't have either a KX3 or PX3, and my 2m work is limited to FM, but the problems that you describe could be due to various fixable problems. For example, some P3s had spur problems due to bad electrical contact between parts of the enclosure, as well as improperly attached BNC connectors on

To really do this right, you would need to add factors for things like IMD, QSK, fan noise, duty cycle, ease of tuning, etc. Cost per watt is only one factor. Of course everyone would have their own personal concerns, so you could add a place in the spreadsheet where the user could weight the

I also ordered on the 27th. On April 2, I was told they would ship in 7 to 10 days. So that comes out as April 9 to 12. Unfortunately for me, I will probably have to wait an additional 3 weeks or so before they will get through customs here! 73, Vic, 4X6GP/K2VCO Rehovot, Israel

Re: [Elecraft] OT - Looking for vendor in Columbia, SC

I'm a little far from SC to answer your specific question, but my advice is to go to a big truck stop or other place that has CB equipment. They have all kinds of mobile antenna stuff. You could even pick up a 10 meter linear amplifier if you need one :-) On 25 Mar 2015 03:06, Ian Kahn wrote:

Re: [Elecraft] RX antenna

The preamp is on or off per-band and per-antenna. So for example you could have it on with the rx antenna and off with antenna 1 and on for antenna 2 on a given band. Possibly when you turn the rx antenna on or off you are also changing the state of the preamp, and that is what the ham pod is

I'm sure it would be easy to add a pickup to the sensor yourself. It could be done with a toroid transformer placed on the center pin of one of the coax connectors. On 14 Mar 2015 22:13, Jobst Vandrey wrote: I operate almost exclusively with digital modes so I would REALLY like to see a new

[Elecraft] Useful P3 feature

Here is something I would like to see on the P3. The P3 saves the REF LVL setting per band. But of course the noise level on a given band varies as conditions change, and I find myself often adjusting the REF LVL. The optimum setting is with the REF LVL just below the noise level. Setting
