K3 won't TX in FT-8

Group,

         I am unable to get my K3 to TX any RF when set up for FT-8.
Hardware is K3, Behringer U-phoria UMC202HD USB sound card running on
WIN XP with most recent version of WSJT-X software. FT-8 settings Radio
Tab: baud 38,400, data 8, stop 1, handshake none, PTT CAT, Mode
data/packet, split none. Tests of CAT and PTT are both successful.
Soundcard tab is set for the Behringer card.

         Soundcard is cabled to LIne In, Line Out on K3. I am in Data A
(USB) mode. K3 Menu Mic Sel is set to line in/line out. Waterfall
displays signals and they decode properly.

         When I click the tune button in the FT-8 software, the K3 goes
into transmit but there is no RF out. When I press the tune button on
the K3 I do get RF out. When we briefly attached a headphones plug to
the soundcard out lead that had been connected to the K3 line in we
could hear the tuning tone when clicking on the tune button in FT-8. I
do AFSK RTTY without difficulty so I do not think the line in jack is
faulty.

         Ideas, please.

                                             K4KGG, Larry

Re: K3 won't TX in FT-8

Larry,

FT-8 is no different than any other data mode, so if other data modes
work look carefully at the FT-8 computer setup.

One thing I can say is that you must have 4 bars of ALC showing with the
5th bar flickering. If you have no indication on the ALC meter, that
means the K3 is not getting enough audio from your software application,
and you will have to find out why - perhaps the "power" slider in the
FT-8 application is set too low.

You might want to take a look at the data mode setup on my website
www.w3fpr.com. In the left column scroll down to the last entry and
click on it to get to the article.

Re: K3 won't TX in FT-8

My KX3 cuts off input if the mic gain is set too high. Maybe same issue for your K3?

Re: K3 won't TX in FT-8

This says the Line Gain on the K3 is too low.   Or the PWR slider on the
WSJT right side is too low.   Be sure in the F2 menu / Settings, the
Audio panel has the correct Audio IN and Audio OUT selected under
Soundcard.   Should be USB CODEC.

Don's info is very correct and very complete.   Don't pay attention to
what others advise unless they have a K3 or K3S or KX3. Their advice on
audio levels will be incorrect as the Elecraft radios handle audio and
power quite differently the JA radios.

Bob, K4TAX

When I click the tune button in the FT-8 software, the K3
goes into transmit but there is no RF out.

Re: K3 won't TX in FT-8

Check audio in level. Too low you will not see RF out. Too high radio will
go into protect mode with no power out.
