Re: [Elecraft] K3 MD command question

Thanks for all the emails, and I did finally realize there is a simple solution to my problem. BTW, I did RTFM. Band memories? Done that years ago. I am an engineer by profession, but the Elecraft (and any other modern) rigs are complicated and it’s easy to miss things or not interpret

Re: [Elecraft] K3 MD command question

Hi Bob, You're seriously overthinking this, perhaps due to a failure to RTFM. On sideband, Elecraft firmware automatically defaults to the "right sideband" for each ham band. If you choose either of the RTTY modes, it will default to LSB. If you choose DATA A, it will automatically switch to

Re: [Elecraft] K3 MD command question

Bob, I suggest you set up SSB as you want it - Compression and TX EQ as well. Then for digital, use DATA A - it automatically turns off compression and TX EQ. All that can be accomplished with VFO A, no involvement with VFO B unless you invoke it. Know that a double tap of A>B will transfer

Re: [Elecraft] K3 MD command question

A number of people have asked what I am trying to do with the macros, so here is a quick explanation. In a normal day I'm switching between CW, digital and sideband frequently. CW is easy: VFO B is always set the way I want it for CW. Digital and sideband have to share VFO A (too bad there

Re: [Elecraft] K3 MD command question

Bob, I believe you are ignoring the ALT button (hold of the left side of the Mode button). Why use a Macro?  Set  the K3 to SSB on the band of interest and change the mode with the MODE button to select SSB the normal sideband for that band, If it is not correct, hold the left side of the

Re: [Elecraft] K3 cw rise time

Hi Tony. According to the K3 mod page, this was introduced at about s/n 280 so you're good to go. You made me wonder why I hadn't heard of it! I have K3 #486 and I've done almost every mod that they have come up with.. 73, Carl WS7L On Mon, Apr 12, 2021 at 11:35 AM Tony - KM0O wrote: > Hello,

Re: [Elecraft] K3 with N connectors ?

Not to start a flame war about N vs UHF connectors, I prefer N and built my KPA500 and Hardrock 50 amps with them. My KX3 remains BNC, and any cable I have that is disconnected often is a BNC, sometimes with a BNC male to N female adapter, which are really common. No one but Hams still use

Re: [Elecraft] K3 with N connectors ?

My K3 Has all BNC connectors on the back. My preference as it travels some for Field Day, special events, etc. Makes it quicker and easier to set up and take down. On Sat, Apr 10, 2021 at 11:00 AM Don Wilhelm wrote: > Larry, > > One local ham had me change the UHF SO239 connectors to N

Re: [Elecraft] K3 with N connectors ?

Larry, One local ham had me change the UHF SO239 connectors to N connectors because he does not trust the UHF connectors. I know he recently sold it, maybe it is the same one. It is easy to change them back to UHF type, but it definitely did not come from the factory that way. 73, Don W3FPR

Re: [Elecraft] K3 - no output power

Just some notes for future folks reading this. I always replace D1 and Q6 together. Other notes re Q6 and D1; 1. Poor RX on 24 and 28Mhz 12m 10M only and TX gain is OK. Q6 a 2N7002, OR D1  on the LPA can Suck the RX down on these two bands!! 2. Slow ramp up of TX power output. Typically worse
