Re: [Elecraft] Frustration with Elecraft

I'm not aware of any electronics company that doesn't, from time to time, sell and ship a product with faults. For what it's worth, that's why the company provides a warranty. Otherwise, no warranty would be needed if they are "perfect" 100% of the time. Won't happen! Seems some folks are

Re: [Elecraft] 6m off-frequency

You say RIT is not engaged, but what about XIT? Either of these being ON can cause an issue in this regard.Additionally, the way one person tunes to a SSB station may cause some frequency disparity between two stations. Excercise: with eyes closed, tune to a station and then look at

Re: [Elecraft] mic

On Jim's points, I fully agree. It seems hams are prone to over complicate a rather simple issue. There's more than adequate mike gain in the K3S, thus I find no technical reason for the use of an external preamp. The internal EQ of the K3S again is most adequate to correctly tailor

Re: [Elecraft] Preamps in K3s

I had to refer to the manual for this. Pre 1 is available for all bands and has 10 dB gain. Pre 2 is available for 12/10/6 M and has 20 dB gain. They are not stacked. Bob, K4TAX Sent from my iPhone > On Jun 10, 2017, at 9:48 AM, Jim Miller wrote: > > I'm confused a

Re: [Elecraft] {KX1} Antenna Matching Question

I've never been concerned about a SWR of 3:1 or less on HF. Even with a 3:1 SWR, depending on feed line loss, most of the power is reflected back to the antenna and is radiated. Now if the length of feedline has 3 dB of loss at the given frequency, then approximately 1/2 of the reflected

Re: [Elecraft] BL2 Balun Question

Your operation is similar to one I encounter when operating from our RV. A balun has several primary and in may cases mutiple functions. Some, all or none may be contained in the specific balun design: (a) operation between a balanced and an unbalanced circuit. Hence BalUn meaning balanced

Re: [Elecraft] K3s pre-purchase question

Based on your current operation and your present listing of equipment, I'd suggest the K3S-100. You have a tuner so no internal ATU unless you want the internal automatic convenience. You have a good mike, I use one of those myself. As to filters, the standard filter is most adequate and

Re: [Elecraft] K3S Microphones

I use a Heil PR 781 with great success. The K3S TX EQ is set as follows; -16 dB @ 50 Hz, -12 dB @ 100 Hz, -6 dB @ 200 Hz, and 2400 Hz @ +3 Db, 3200 Hz @ +6 dB. Working distance to the face of the mike is 4" to 5" on axis {one fist} so as not to enhance bottom end due to proximity effect,

Re: [Elecraft] data modes (USB/LSB or DATA) using KIO3B sound card interface

I have the K3S USB cable connected direct to one of the USB ports on the computer. As to radio set-up, see page 33 of the manual for details. I use DATA A mode for PSK & other data modes. The software is usually FLDIGI, HRD/DM780 or WSJT-X which all work under Windows 10 successfully and

Re: [Elecraft] 12 meter K3 RFI from nearby FM station

One other item, if available, try another brand/model radio using the same power supply, location, antenna and such. If it is present on that radio, most likely it is radiated. If it is not present, then most likely it is generated in the K3. {To which that is an entirely different can of
