Re: ZbitX battery holder wiring
Other end looks good, but thanks for the heads up. I think pigtail was stripped too aggressively. ?A little liquid electrical tape and as good as new.?

Re: ZbitX battery holder wiring
Maybe your batteryholder does have the same problem like mine in that the poles at the other end where not connected together also. Easy fixed with soldering in a wire.

type? git stash? and then run ./update that should fix it. were you looking at some source code that got modified by mistake? - f
I tried to update to 3.051, but I got this error message: “Error: your local changes to the following files would be overwritten by merge: sbitx Please commit your changes or stash them before you merge. 础产辞谤迟颈苍驳”
I have updated the zbitx keyer with a minor update. the new software update version of sbitx is now 3.051 (moving from 3.05). Can the cw users try out this version and let me know? I could manage upto 25 wpm (my paddle skills are lousy) You have to just run ./update to get to the new version - f

These are the set? I was using at the time of testing.? ?Looks?like they aren't really designed for a?constant high current?discharge,?
I have a number of other batteries which I will have to dig up the specs to see if I have any set of batts that will handle the current?needed on tx.?

I purchased these:

They appear to have the right curves. ?8A continuous draw.? High Capacity.

We will see how they work when my radio arrives.

Can do. I will bung this into the SET(tings) of the front panel. - f

I'm using the batteries.? They are older(recovered from Laptops) batteries. So that could be the case why it's dipping.?

Re: ZbitX battery holder wiring
I will design a batter cover. This is unnecessarily dangerous!

Just a thought, but what if the user could simply toggle the waterfall display off? That could be an easy way to avoid the problem until a better solution presents itself?

You will get 5w if your power supply holds to 8.4 volts o transmit? i can see from your readings that the dc supply is dipping to 6.8v on transmit. This indicates that the power supply is current starved

What are other seeing with the power levels? I have a QRP Labs dummy load that I connect my volt meter to get a peak voltage reading.?
The voltage on the radio is 7.7v, drops down to about 6.8-6.9v when tx. The Driver is set to 100 on all of the tests, and the mode was 2TONE.
When I tx into the dummy load. Based on the calculation its showing I'm outputting about:

I'm thinking that's on the lower power levels than I would have expected. Are others seeing the same thing ??

The chugging sound is actually?from the I2C lines to the Pico processor that is on the same board as the speaker. They are absent with the head phones.? If I reduce?the data running on the I2C lines the chugging sound goes away. I hope that in a future update we will be able to compress the data (most of it is the waterfall data). - f
I received mine today as well, very exciting! I upgraded the software to 1.05/3.05, everything seems to work. I noticed the "chugging" as well, along with the decoder portion of the screen flickering. I am wondering if something is getting bogged down with the decoding/display/audio process

I installed the batteries and followed the set up in the manual including setting the time using an hdmi screen. I linked the wifi to my phone hoping this would pay dividends when in the field. It first the radio seemed deaf, but playing around with the IF I started to hear signals on 20m and 40m. I found CW reception difficult the radio seemed to make a chugging sound as the decoder tried to work. The back of my radio was warm but was not excessively hot on rx. I tried FT8 decode seemed sluggish to start but once running was fine.
When the time needs adjusting must I always connect to an hdmi screen or is connecting to my phone wifi sufficient to update the time? Is the chugging sound in cw mode normal? Will the operating manual be updated further as time progresses. Should I be upgrading software and firmware or are these updates to be considered as beta and optional. How would HF signals prefer feedback to be given as I assume they cannot monitor every post trawling for bugs and questions.
Finally I like the radio and form factor. Thinking about a 3d printed sloping stand which when reversed protects screen and knob. Thinking 3d printing battery cover or using stand to hold battery holder. Can audio be directed via Bluetooth to an amplified speaker??
Thank you Farhan for this radio?

Re: zBitX ft8 TX signal comes speaker
Oh -- and make sure that some sort of "split" isn't turned on.? ?I've done that by accident more than once, and you get zero output power, if a totally different band is selected (or so it seemed to me at the time).? ? That was the most frequent reason that I had zero output.
Good luck!? ? Ham radio is a learning hobby!

ZbitX battery holder wiring
Point of caution! Noticed the battery pigtail has bare wires exposed probably when stripping outer insulation. Could short if wires twisted. ?Easy to fix however .?

Re: zBitX ft8 TX signal comes speaker
Hi Ben, -- did you email HFSignals themselves (this is a user group) and inquire about returning it for a replacement (or if you prefer, refund)?? ?Perhaps they can help you.
