Re: sBITX V2 serial # 001 Current Status and question #sbitx_v2


 

Neil,
Is this power output reading from your radio's display or is it from an external power meter?
Can you remind us if you have a v2 or the de?

I would strongly urge that you do your tests into a good dummy load with known good connectors ... ideally with no cable ... before you do anything significant inside the rig.? And make sure you verify the power out with a decent external power meter instead of just relying on the internal readout.

When troubleshooting you want to simplify as much as possible at each step.

Sorry to reply to my own post, but I was hoping someone could advise me.
Is there something I should be doing (see below) or should I be happy with these numbers?

Thanks!

Hi all,?

After resolving my update woes (thanks Art N2AJO !!) I feel things are pretty stable.

I know that the rig should be capable of upwards of 40 Watts on the lower bands. I'm not seeing that at 100% drive.
Here is what I'm seeing, which I'm happy with, but would like to know if I need to tweak anything or look for a problem:
(Into a fairly resonant antenna on most bands but tuned to close to 1:1)
BAND? ? ? ? ? WATTS
80? ? ? ? ? ? ? ? ?15
40? ? ? ? ? ? ? ? ?18
30? ? ? ? ? ? ? ? ?20
20? ? ? ? ? ? ? ? ?21
17? ? ? ? ? ? ? ? ?12
15? ? ? ? ? ? ? ? ?12
12? ? ? ? ? ? ? ? ?10
10? ? ? ? ? ? ? ? ?11

I would say accuracy is + or - 2 Watts with this setup.
Sorry, I have misplaced my dummy load.

Anyway, is there anything I should be doing or looking at.? Otherwise, I'm enjoying the rig.
