sBitX-V3, what is the performance, support, price and weight?

 

im thinking of buying this just for dev and learning.?

-is power out (watt) adjustable??

- -If so, how much is max power out for each ham band it can handle? (approximately)

- does this radio work after 30days? (no warranty for board kit(199usd) )

--If so, how much do you use it per week?

- how much does the sBitX-v3 board weight? (i can read around 2kg for AIO, but no information about the board.)

From a scale of 1-10 in performance, support, cheap, where would you rate this as a owner?

It depends on everyone, there are radio amateurs who still like to learn to modify with their own hands and there are radio amateurs who prefer only to "operate the radio" 10 I can not give but 9 yes for what I learned!
 

Power is adjustable.

I have operated my v2 for 6 months or so.
No operation issues.
I run the digital modes for weeks at a time 24-/7
Power reduced to about 5watts with a small hf amp to bring it to around 40watts when needed.?
WJST-X,? WSJT-Z??
GRIDTRACKER
For voice, I changed to a better condenser mic and the issues were cleared, with good reports.

My overall experience has been very good performance.
I have a pi4 with 4gig mem
Reasonably priced..
I am looking at purchasing a second one.
The board kit only.

From what I seen, yes there are issues, however, it is more of a experimental radio at this stage and each issue is being corrected.

The sensitivity of the tx power transistors to be easily destroyed has been an issue but each revision? has made it better, hopefully some more hardware or software revisions? will? eliminate this completely.

I am looking forward to the stage when the unit? can run ssb completely remote thru a browser and not thru a separate remote pgm.

Over time? hopefully we will see more control buttons / options.

I see many additional developers? and am greatful, they are willing to share? their expertise.

Support is always an issue with a developing product , it could certainly be better and can be very frustrating.

Hopefully, as an experimental rig, we will see? better schematics,? with test points, voltages, current readings,? etc.
This will come with time.

Performance 8
Price 7
Support 5

thanks for replay, i notice i forgot to add #sBitx to this message/topic, not sure how to do it after starting a topic.??

I didnt quite understand "Power reduced to about 5watts with a small hf amp to bring it to around 40watts when needed.?" but i like what i see with this dev board. Perhaps someone knows how much the sbits board weight?
 

For the transmitter? I set it to around 4 or 5 watts. I do have a small hf solid state amp connected as well? to bring the power up to 40? or 50 watts.

Keeping the sbitx tx output low allow me to run ft8 modes for hours, an transmitter? heatsink stays cold.

The? solid state amp is built for 150 watts? so running it in 50 watt range, is keeping both devices way under their capabilities.

I have run this type of setup on my digital modes for years with no tx failures..

Joe,

can you post a link to the condenser microphone you are using?

Thanks and 73,

Here is the picture and info of the mic I use to replace the one in the current? mic ??
High gain mic

Nobody will notice the difference between 25 watts and 50 watts (half an S unit). To make a difference, you will need a 300 watts amp (2 S units).

If you are waiting for a response from dx stations, then make a well-functioning antenna (without a tuner) and enjoy the 20 Watt output power. At the same time, experience when there is a good spread in which direction, then success will not be missed.
