(tr)uSDX Beginners

[DD5MA]

Hi All, now my (tr)uSDX has finally arrived from *Rxxxx*. And it is really fun! It works even great with 5 Volt.
Now my questions, the TX has Firmware 2.00i installed.
- How to work split?
- I guess Menu 10.1 Backlight is obsolete in this firmware.
- How true is the display value for power out and efficiencs? According my own measurement it shows approx. 5 % to much. As delivered 8.6. R-Shunt is set to 19.
- What is ATT2 good for?
- Does anyone already has experience with AM RX on medium and long waves?
- 8.4. IQ Phase is not available at my rig.
- How to transmitt CQ Message 4.2.?
- What is the experience in changing 8.1. PA Bias from 0 to ... and 8.2. PA Bias max from 128 to ... ?

First tests shows that the Mic is not very sensitive. Idea to increase the mic gain?
It was also reported that there are cuts in transmission?
I am also interested in a solution for a extern Mic/Speaker. Any hints?

Thanks a lot and vy 73 DD5MA

I actually have an extra question, is there a possibility to also have 800Hz CW filter please ?
500HZ is ok but 1K8 is too wide.

Thanks es 72

I took a heil head set that has a separate stereo headphone jack, a mono mic jack and a mono jack for ptt. I cut and soldered the two mono plugs for mic and ptt onto a stereo plug making sure the mic was on the ring and the ptt was on the tip.
