Hi,
?
I am selling my xBitX v3, only bought (ordered) 05-21-24 directly from HF Signals.
?
I thought I would use it more but find my IC-705 and SDR Control (MacOS) easier, or I should say more familiar.
?
It has JJ's 64Bit OS and corresponding sBitX version, haven't updated to recent release.
?
I will include a USB drive with the config & settings backuped and a 50ohm dummy load.
?
It is in its origanl packing box with the paper work showing the calibration settings and package content.
?
I am looking for ?350, saving import duty, I am in the UK.? Can post (?10 Special Delivery) or collection.? International would depend on shipping costs.
?
Also, if interested I have two Zeee Power 3S LiPo 5200mAh with an ISDT Q6 Nano charger and cables for ?75.00 plus ?5 postage.
?

Assuming the designer promotes the initiative, would you partecipate in crowdfunding the production of q.ty 100 batch of an assembled version of the zBtix? The crowdfunding would be of the all-or-nothing, reward kind, so no charging would take place if the goal is not reached, but there is no guarantee the production would actually start if the goal is reached.Tentative goal: 20,000USD (to be defined). (so the funds provided by the participants would be about 200USD each) The reward would be a discount coupon, for the same amount, on the purchase of a completed / tested unit (tentative price 300USD). All the results of the project would be published as open source. What is the zBitx:? What is crowdfunding: Comments from Ashhar Farhan: /g/BITX20/message/113592 /g/BITX20/message/113620
Thank you for voting.

sBitx_log file export into cqrlog without GRID - partially solved
Today I made some QSOs and first edited the exported adif file using Notepad++.
I renamed STX_STRING to my gridsquare and
I renamed SRX_STRING to gridsquare
after that I copied it back to the RPi and imported it into cqrlog.
?
Data that was missing until now appeared in the GRID cells.
The names stx_string and srx_string were, in my opinion, poorly and arbitrarily chosen by sbitx.
I suggest that the coders consider correcting the names if possible.

Are these values tweekable in hw_settings.ini?
The scale data in the hw_settings.ini file contains the maximum performance available in the given band.
It is worth using the data provided by the manufacturer.
But if you like variety and modify these, you will either improve or degrade the output level.
Important: always have a copy of the original data!

Can you send the updated link?

...just wondering: has someone tryed installing SDRPlay sw in the sBitx?
The sw "should" be binary compatible, but SDRPlay removed the images and stopped development.
However the last versions are still available in the net (the Internet never forgets...):
That doesn't mean it will actually work on different hw of course.
But it would be really nice if a double-channel version of sBITX could do diversity with SDRuno...
Sci-fi I guess...

the title and the question are incorrect,
because I want to transfer the content from sbitx_log in .adif format,
which is correct sBitx_log file EXPORT into cqrlog

I'm also interested in CW improvements?to the straight key response (since I sometimes use an external keyer).? ?I tried looking at devfarhan and modem_cs but I couldn't really figure out what improvements have been made.
Can someone summarize any improvements made over, say, the last year, that would improve the CW response to the straight key?? ?I last tried that months ago and my impression from V3 code was that it still had some delays.? ?Does it still check only every 10-20 times per second, and is this adequate???
Sorry for the multiple questions, but figuring all this out is tedious. THANKS for any direction and wisdom, Gordon KX4Z

I've made three contacts with it already on 30m CW, but I'm glad to hear that someone is working on the keyer. Right out of the box, the keying is very rough.
?
Is there a thread here that will show me how to get this dev code, so I can try it out?

I'm confused is? the max pwr on the v3 25w or 40w

Will do.? The individual W8DIZ amps are very flat from 1-30 MHz. The spice model as I posted has a 0.5 dB drop from about 14 to 30 MHz for the pair. I'm cautiously optimistic, especially since this effort is based on advice from Allison.? I've finally learned enough to understand at least some of what she was trying to teach. Hihi

With respect, Jeff, you'll not get BITX20 community review if you post something to a discord group most here don't use.? Why not post it here?
