Re: Debugging FT8 decoding #sbitx_v2
Gyula & Salim, Just check my test piece which was at 90% gain and decoding. Even at 100% if worked fine. So Salim must have a high gain antenna to over load. Raj

Re: Debugging FT8 decoding #sbitx_v2
Gyula, Thanks. Yes you are correct. The RX gain was too high in the screenshots. 73 de salim vu2lid / n8li

Re: Debugging FT8 decoding #sbitx_v2
Salim, just a suggestion for FT8 settings. The AGC must be switched off so that the received signal is not amplified, then your answer is correct. It can also be seen in the waterfall that you are

Re: The content of hw_settings.ini is incorrect #sbitx_v2
Jack, thanks for the information. When I take the time to tear apart the v2, I'll check out the Bias as well. I didn't have to change IRFZ24s, I just wanted to do the May 4 settings. The success is

Hi Salim! Sometimes a hard reboot solves the problem. Raj, vu2zap

Debugging FT8 decoding #sbitx_v2
Hi, I am trying to see why FT8 decoding doesn't seem to be working on my v2 sBitx. Time seems to be synchronized. I can also see several fldigi -i processes running (please see the screenshot of a

Re: The content of hw_settings.ini is incorrect #sbitx_v2
Gyula, in the DE and also in the V2 when I have replaced PA IFRZ24Ns and re-trimmed the PA_BIAS potentiometer, for what it¡¯s worth I have found that I need to re-tweak the scale coefficients in

Re: No talk power out #bitx20 #sbitx_v2
Farhan. I tried the 2 tone mode this morning with the same conditions and got about 6 watts on the meter. I also tried the internal mic and got the same , almost zero power out , as with the supplied

sbitx v2 swr off
v2 sbitx after swr bridge calibration and txcal to a known swr of 1.78 shows 1.1? ? is this close enough or do I need to edit the .Ini file in the swr brige to change the settings to get better

Re: The content of hw_settings.ini is incorrect #sbitx_v2
The problem is solved, although the scale values stored in hw_settings.ini are far from the default. I assume it's due to the variance of the parts. The value of the bridge stored in user_settings.ini

Re: Sbitx v2 transmit audio is CRAP #microphone
With the supplied microphone on both of my sBitx DE and V2 I got bad audio reports, but with this mic, http://www.qrpkits.com/microphone.html I get great reports. I use these mics on all of my Bitx

Re: IRFZ24N #sBitx
Yes and recommended conditions are for SMPS and similar operations where the device is saturated.? Not the graph,? charge on the gate to specify operating behavior? its about the amount of charge

Re: Sbitx v2 transmit audio is CRAP #microphone
I agree with farhan, The 12V bias is fine.? However the source of that bias is unfiltered 12V and it can have power supply and RF noise on it.? It makes the radio extremely sensitive to self

Re: No talk power out #bitx20 #sbitx_v2
The Elecraft mics, I know, require bias or you get no output. 73, -- Dave, N8SBE

Re: Sbitx v2 transmit audio is CRAP #microphone
The transmit audio problem is usually a challenge if the microphone is picking up RF. There are hundreds of these radios that are working with the 12v bias, so it is less a design issue and more an

Sbitx v2 transmit audio is CRAP #microphone
Why is the microphone voltage so high? My friend measured and saw almost 12 volts. He the placed variable resistor across tge circuit reduced to 3.5v and had a lot better transmit audio. Please advise
