Re: [Elecraft] Mobile from 117 VAC

Although when using our travel trailer, I operate the radio from the 12V battery system,  I do have installed a 12 volt to 120 volt pure sine wave inverter.  This takes care of things such as computer, microwave, TV's and of course the all required "hair dryer" and etc.    The unit is rated at

No transformer needed.  The gain settings on page 55 of the manual are sufficient for the SM 58.   Just wire it as an unbalanced output.   I use both the rear or front MIC inputs with no issues and a variety of different mikes. 73 Bob, K4TAX On 10/4/2017 12:18 PM, Stewart wrote: OK

Re: [Elecraft] K3s rear mic connector and shure SM58.

No preamp required.  Set the Mike gain via the menu to high. Easy to wire the mike XLR to an unbalanced circuit.   Pin #1 & #3 to ground and Pin #2 to MIC high.  See page 55  of the manual [MIC SEL] for details. If you close talk the mike it will be bottom end heavy. Typically no closer than

It's not how many knobs but..how many knobs does the operator know how to use correctly. Bob, K4TAX Sent from my iPhone > On Sep 30, 2017, at 5:54 PM, Fred Jensen wrote: > > QKK? "How many knobs does your radio have?" > QKK 146 "My radio has 146 knobs" > > QKU?

Re: [Elecraft] SDRPlay as panadapter

I'm using the SDR Play {RSP 1} and HDSDR very successfully for my needs.  However, I do not use the IF output on either of my radios.  I use the SDR Play receiver by  picking the signal off of the RX ANT  IN and OUT on my K3S and I pick the signal from the Band Pass filter of my other two

Re: [Elecraft] 60 meters and the K3S

I use memories 61, 62, 63, 64 & 65 for 60 meter frequencies and mode.  You can choose memories of your choice.  By doing this then pressing V-M one can "tune" through the memories.  Finding one you wish to use,then press V-M again and the radio goes there. Those frequencies are are as follows

Be sure you have updated WSJT-X to v1.8.0-rc2.   This version does correct a couple of issues in the rig configuration file. 73 Bob, K4TAX K3S s/n 10163 On 9/29/2017 10:49 AM, Don Wilhelm wrote: If all you changed was the computer, then the problem is with the computer setup.  Is the

Use the Elecraft Utility, select Edit Power On Banner and make the changes you need.   Just be sure there are no extra letters or symbols in the box.  Only 22 characters are allowed. Of course you will need the radio powered up and connected to the computer.  Also check the port number and

Re: [Elecraft] Low Tx Data Sound Output volume

With FLDIGI there are two modes for DATA. PKTUSB is preferred for all modes except where one chooses PKTLSB for AFSK. The CAT command will handle the radio mode switching. Thus one does not have to turn to the radio and initiate the REV mode. Bob, K4TAX Sent from my iPhone > On Sep 28,

One other point is the hams mentality ;   "I've operated hundreds of ham radios and I know how this one works".  HA!   Better read the dang manual two or three times.   Also the Fred Cady, KE7X has a wealth of information not included in the standard Elecraft K3S Owner's Manual. Regarding

Re: [Elecraft] New product idea for Elecraft...?

Between my operation of SSB, CW and digital modes, I find the radio makes all the changes necessary as I change modes and bands.   Thus once configured as I operate, no changes to any menu's are needed. One thing I did conclude...the radio is a lot smarter than I am.  Thanks Wayne,
