I am a programmer, and the fact that the radio has a built in RPi was the point that sold it to me (together with the bands covered, features, power level, and portability). I do have an antenna tuner

ps.: There is one sentence missing from the previous message: for the EZ Data operation you will need a USB stick, which is advisable to store in a safe place so that it is accessible when needed.

James, The original sbitx.db stores the log content, so you didn't lose anything at 0 QSO. The hardware_settings.ini file contains the drive scale required for your device to transmit. If your

Hey Travis, Yeah, I’m thinking the same, actually. The issues I see are: * Interrupting receive audio to get speech from Orca/Speakup/whatever * Input. USB keyboard perhaps? Because I don’t think

Jsem ve fázi ?ivota, kdy jsem si myslel, ?e mám v?echna rádia, která jsem kdy chtěl. Dokud jsem neviděl zBitx. Mo?ná pot?ebuji je?tě jednu.? 73 Michael N4MJR

The power output is proportional to the square of the drive number I always come up with my own calibration numbers by starting with the power set to maybe 30 to 50% and measuring the output power.

To upgrade the RPi in the zBitx will 'require' repackaging the radio, as the RPi it ships with, an RPi Zero 2 W is about half to one-third the volume of an RPi 4 or 5. The RPi Zero 2 W has the same

David, I believe it piggybacks the real time clock modules I2C pins and power pins. Joel N6ALT

Buddy. I'm figuring we can just install espeak/orca on one of these radios, and have complete speech access that way.? It's possible we'll need to swap out the raspberry pi board, to either one with

Hello. Wondering how important the original sbitx.db and the hwini files are from the original disk I got when I purchased my unit a few years ago? Before you ask, I DID back up those two files to a

Thanks Evan now it works. Ramón

Well, who knows how it got damaged. Don’t forget to put D7 back in there, and it wouldn’t hurt to put something even a little beefier like two or three of the one amp diode in parallel. This is

You can buy one prebuilt. https://www.etsy.com/listing/1809193390/power-protector

It was in fact one of the IRF510s that failed. So I will replace both with a fresh pair, then proceed to recheck all of the active components in the PA section. If all is well, I believe I will

With all the fanfare around the zBitx, I've heard nothing about sBitx. When will we be able to order the current, or next(v4) iteration of SBitx? 73 -- Mike - K8MCB
