[Elecraft] K3 a few new user questions

[Ray G3XLG]

Hi Richard

More replies, I'm afraid!

However, changing from DATA-A to PSK-D on the K3 does appear to give full
output with no trouble! 

I'll check it in the morning with a local HAM to see if in fact it was
giving out a true PSK31 signal!!!

Ray, 

Are you still getting ERR PTT messages? NO If you are, then it is likely 
that in your N1MM or DXLabs configuration you have something set that is 
telling the MKII to assert its hardware PTT output. For example, if the 
Router were configured to use COM6 for FSK, with the PTT box checked 
beside it (YES), and you had RTS on COM6 set to Always On in the N1MM 
Configurer (NO), or if the Router were configured to use RTS (YES) on COM4
for PTT 
and you had RTS on COM4 set to Always On in the N1MM Configurer (NO, Always
OFF)  and/or 
in the DXLab Commander configuration (NOT YET CONNECTED) , that could be a
cause. 

Once this is resolved, when you say no power output, are you at least 
getting PTT, i.e. the K3's red TX LED coming on? (YES, the RX switches over
to TX, the LED lights, but no power out) 

If not, your PTT 
configuration needs more work. I believe that microHam suggests using 
RTS on the radio control port in N1MM Logger for PTT (YES)  (set DTR to
Always 
Off), and if you are using the K3's ACC port for PTT (YES, I think so) ,
setting the Router 
to use PTT2 for PTT in digital modes, but I may be misremembering this - 
consult the sample settings documents (will do) under Support at the
microHam-USA 
web site, and the MKII user manual for the Router's PTT settings. In 
DXLab Commander, you would set RTS on the primary CAT port to PTT and 
DTR to Off, and in Commander's General configuration window you would 
check the "suppress CAT" check box in the PTT pane. 

If you are getting the K3 into transmit mode, but no power output, check 
the following: In DATA A mode, look at MAIN:MIC SEL and make sure it is 
set to Line In (YES). Now adjust the K3's Mic gain control to set the Line
In 
level - I believe the default level is zero, which will result in zero 
output. You need to adjust the MKII's TX level control and the K3's Line 
In level control so that you can see 4-5 bars on the K3's ALC meter 
(with the meter in ALC mode) (I can get no ALC or power out even with Max
line/mic gain & max TX router gain). Once you have done this, if you set the

K3's Pwr control to 40W you should see 40 watts (4 bars) on the K3's RF 
output meter.
