While the uB is capable of receiving 630, you'd have to add your own
bandpass filters.  I remember someone asking about transmitting down
there once before but don't remember what the answer was.

Thanks AA9GG I had seen them too, the problem is that the first is only for the encoder and should be integrated and I am not able
The second one has some problems in the compilation and uses so many functions that I don't have type cw, swr etc.

I remember 160m just needed a lowpass filter. I am not sure, maybe it depends on the versions, whether changing (increasing) the values of emitter caps such as C81 might be useful for lower bands. I am not aware of using in on TX on MW or LW. About the attempts of using it on VHF or above, I would be interested if different from using a transverter.

Re: dc rcvr ?

Your BFO is in the middle of the passband. you will have to get into calibration menu (choose setup option and then BFO calibration) and then tune the bfo until it gets to a side of the filter skirt. i guess there are videos on how to do it.

Definitely its a superhet. The xtal filter is wide enough for ssb. Try tuning in some voice signals to get a better feel for it. Many arrive with bfo alignment way off.

I use a nescaf audio filter with mine to get a narrow cw bandwidth.

now have ubitx receiving -
tuning across cw signal sounds like
dc (direct conversion) rcvr with audio
on both sides of zero beat -
thought ubix was single signal like
front panel says either usb or lsb -
perhaps is not yet adjusted ok ?

I had an encoder on my BitX40 but wound up going back to the 10-turn pot.  I just made more sense since it's single band.  Plus I was fighting trying to re-write the menu stuff to work with it.

If you google 630 meter band antennas you'll find several examples of loaded antennas that will fit in a smaller space. Also I've read articles where people are coupling to a tree and using it for an antenna with some success.

Hello,

I’m kind of having a hard time getting my head around the very concept
of a 630 meter band. A quarter wavelength is over 157 meters or more
than 500 feet. Humongous antennas - wow The mind starts to boggle.

I have not idea how the Greek Zero thingy got mixed up as I only type the bitx20 group address. My text was the only content on it. Not sure what the system is programmed to do.
My question was not sent on the blog of bitx but its address on my email app with no Greek content anywhere.
