Re: BITX20] FETs on sale

Bob Lunsford
 

Before reading your message, I kept looking at the spec sheet and could not see a Ft or something that gave an upper level frequency spec so began to wonder about it. However, some transistors were used for power supplies and for 40M QRP finals in the past so thought it might be usable. Oh, well...

Great part, if you are building a power supply.
An RF amp, not so much.
IRF510  total gate charge:  8nC
IRF3205 total gate charge: 146nC

Those numbers were both taken at a Vgs of 10v, so should be a pretty fair comparison.

Re: GPSDO ubitx ?

Rafael Diniz
 

Hi Ashhar,

Is there a way to know if the Si5351 correct got the 25 Mhz input?

I still did not do the 10 MHz to 25 MHz circuit (I bought a GPSDO with
10Mhz output from ebay). Any way I can buy a 10 MHz to 25 MHz
transverter already assembled?

Regards,
Rafael

I tried something a year ago or so. I was attempting to reduce the
phase noise on Si5351 using an external oscillator instead of the
internal oscillator.
So, this is how it worked. 
1. You take a 10 MHz TCXO, (subsitute this with a GPS source for a
GPSDO) and divide it by 2 in a 74HC74. The output is rich in harmonics
at 5 MHz.
2. You feed the 5 MHz square wave into a triple tuned bandpass filter
at 25 mhz to isolate the 5th harmonic. This will be weak, add an
amplifier of 16 db to bring it up.
3. Feed this to the xin input of the Si5351.
Now, your Si5351 is GPS disciplined.

Thanks Rubens. I just connected the 13.8V to the center, and the
negative to outer, and it is working fine!

I bougth a ubitx v6 basic kit, and I'm wondering what to do with

And btw, in the 12v jack, the positive is the center, and negative the

Yay! I'll be on air soon.

Group,

I stopped using the program, as it is incompatible with my uBITX v4.

I've written custom firmware for the uBITX 6 and got the CAT interface working well with WSJT-X 2.1.2, using the FT817 configuration. I just tried WSJT-X 2.2.2 and it no longer works.  I see in the release notes that they updated Hamlib to a newer version and one of the specific notes was to make it work with the uBITX.

I didn't have time to fully debug the interface as I was setting up for the RTTY RU contest, but I notice that it's using a few more undocumented FT817 commands. Even after adding those commands to my CAT interface, I still had trouble getting it working. I had it working fairly well as long as I didn't restart the uBITX after uploading the sketch. It seems that uploading firmware resets something in the serial interface that isn't done after a normal power up. With 2.1.2, I was able to get the uBITX to reset by setting DTR high on the interface, but it looks like 2.2.2 is using DTR differently as my uBITX resets several times instead of once with 2.1.2.

Thanks. I’m mainly interested in setting up the timer directly and not relying on a library. It looks like there is some code worth studying in that first line.
