One suggestion: perhaps obvious given the others, perhaps not. Maybe you are near some sort of ham club, or at least within driving distance. While there may be a prohibition on swap meets, maybe you

Gerard Any decent 45 MHz crystal filter should work, it has 2 sections. Whether it is 15 or 30 kHz should not be a huge factor under most conditions,? of course narrower is better except for

Hi Reed, I tested the encoder with my multi-meter in continuity mode. When I rotated the encoder I could hear short beeps on the different for clockwise and anti-clockwise turn directions, same with

I would agree that the most likely candidate is the mic element.? I would look into another source to connect to the mic input.? Remember that the sleeve is connected to the PTT line, so you would

Evan, Yes, I think the receiver is functioning now. I followed the #1 PA BIAS section of the MBITX Tune-Up procedure on the hfsignals website. I was able to set the two bias adjustments to add 100 ma

So it seems you have the receiver working.? As stated in the other post from me, I would now do the bias adjustments of the PA.? That would also tell you if the finals are working., though not the

Dale, I am glad to hear that my expectations are reasonable in the neighborhood. Yes, WWV at 15 MHz show up at 15 MHz on the dial although it is pretty weak for me right now. Last night, I heard

I have been following the thread, however not sure I have any good suggestions.? The first thing that threw me off was the measurements given in the first post:? The resistance measurements do not

So the only other connections come from the 8 pin audio on the uBitx board. I am a bit confused because I see other connections across audio components. Am I correct in thinking those are v3 or v4

This is a? V3? kit that needs to be? assembled . I had a stroke in April and unable to build. The outside case is included The ?Bitx is a HF (3-30MHz) all-band SSB and CW transceiver kit.. The

Hi Stephen, I think you should be able to make that path. I hope he is using a horizontal antennas also. The ground wave penalty for being cross polarized can be as much as -20dB. Likely you have

Dale, Thanks for the suggestions. I am really getting frustrated with this thing. I hooked the unit to a fan dipole in the second story attic of this house (in a HOA-restricted subdivision) with both

HI Stephen, Anything other than both the SDR and the BitX connected by an appropriate attenuator or a directional coupler will yield frequency dependent results, and not real numbers. The correct

The 5v pad goes to the output pin of the 5v regulator on the arduino board, or your can do what I did and put a separate 5v regulator on the 5v and earth pads, bend the input pin back on itself and

So is this the only connection to the main board? ?What is on the 5 volt pad?

Dale, Unfortunately, I haven’t made any special provision for coupling. The SDR is connected via coax to a “Balun On Nine - Tiny Low-Cost 1:9 HF Antenna Balun“ located outside of the house. A

For SWR checks on SSB radios I've been known to whistle! However if I need to do that a lot one transistor tone oscillator switched in does it just fine. Allison --------------------------------- No

Hi Evan? ? ? ? ? ? ?Thank you for you advice and help, I will persevere and see what I can come up with. thanks Nigel

Hi Stephen, What is the coupling mechanism between the SDR and the Bitx? If it is perhaps a short random wire for example, I would expect the SDR to read higher on 10M than a lower band as the

Anyone has a ubitx version 6.0 up for sale ? Cordialement, Regards Claude Munger Poirier. VA2SOB LinkedIn : Claude M. Poirier
