And right off the bat... I wonder why this is mentioned on the HF Signals website? "The ?BITX comes pre-aligned. You should do this only if you really think it is out of alignment."

Hi, can someone tell me a simple way to add a ptt switching circuit for my amp please? Can I just use pins from the transmit relay?? Thanks.

Doing a smoke test does not include setting the BFO! No where on the site does it mention that the kit comes pre-calibrated. The software is written to get the frequency close to being aligned. Due to

iz. don't confuse the poor bugg_r There is a procedure for set up .? he needs to follow the procedure to get optimum output in SSB.? Now you bring up a red herring.? What I would find annoying is

Why don't you measure the power and current draw in CW key down?

Thanks guys, I had sort of considered that the Bird 43 was probably not showing peak power being that it’s not capable of without the add on kit being done to the meter so that confirms my thoughts.

Good news. Would be nice Farhan could make a stand alone VHF UHF SSB/CW qrp rig to be used for sats, sota and contests in general. Il 26/set/2018 00:55, "Bill Meara via Groups.Io"

I would like to point out two tricks to reduce noise that worked for me using cheap sdr IF converters. First if you use a laptop, either use the battery (which will be eaten fast) or a power supply

Ok, interesting that a resistor may suffice. If you hear overload in the uBitx then you need the BCI filter or adding some preselection. If you see the overload in the RTL and you hear a clean signal

Decided to do the Pop fix and it all went well. After looking at how others did the mod to a V3 board I opted to install the components underneath. I must be missing something though because the side

Hello everyone, I’m just curious what kind of current draw I should be seeing? ?Here are my readings: 166mA Idling 540mA Keyed w/no audio 1.02A with loud hello into the mic The reason I ask this is

Yes the gain comes from the ubitx first IF amp!? You may have to dial the sdr gain down more. The spurs are the ones we have been talking about for nearly 4 months. I bet if you tune the bitx you

This is great. I have my turnstile antenna ready! ? Go Farhan! Joe

Hi Kees. Do you care to elaborate as to what you think the problem is regarding insufficient isolation? Thanks. Nick
