Re: SBITX V2 - DUAL MONITORS?
|
Scott,
Don't know how you figured it out but it works.. Ctrl, TX, rx.
Questions: 1. When I run the map command, it appears to run with no errors but after I enter the command there is no feed back. Is that normal? Not really an issue? as I find I can select touch screen or monitor for operation.
2.? I have not been able to find which ctrl I can use? beside? rf tx drive to control the audio tx level. I mention this because when I use sbitx thru browser I have much higher tx output.
3. I am thinking of running jtdx, have you ever tried that? on the sbit radio?
Thank again for your help.

Other notes
I run a dual Hamstick antenna in a dipole configuration in my attic.? Because of local limitations, it is not ideal but as solar conditions favor, I can easily make 100+ connections per sessions.? A better antenna/location will greatly improve performance but I have to figure a way to conceal it from view.
I also use a ATU-100 EXT antenna tuner.? SWR is typically 1.0-1.2.? sBitx Watt and SWR indications agree with ATU indications within about 10%.
I am running a DE version with all mods and latest firmware.? After latest hardware mod, I lost a set of finals.? Turns out I neglected to tighten heat sink clamp enough.? After replacement, heat sink got much hotter during digital operation (expected).? I added a small 90mm "muffin" style fan to cool heat sink externally.? Heat sink used to get pretty warm to hot without fan but now with fan, no noticable heat buildup.? I like passive cooling as a design element but I might engineer a thermo controlled fan for extra protection later.
Good luck, Scott
