I bought two 1800s, they would not fit my ubitx pcb at the bottom of the case by a fraction of an inch because of the orientation of the raduino and heat sinks on the short axis of the card, they must

No DHL fees into the US for me, that is. John

No fees from DHL for my bitx40 or ubitx. John

Sorry for the newbie question, but the WA2EBY kit is for 1W drive, won't that splatter like crazy with 5-10W from a uBitx? Or how would an operator decrease the uBitx output power that low to let the

Even easier is using a small object (thumb tack, tiny drill bit, etc) to unhook the black and brown wires from the header and reverse their positions. Then you can change sketches without worry in the

A prior discussion said a fast blow 2.0 amp, I've only seen draws in the 1.3 amp range, so I've been happy with that fuse so far. John

Another easy physical solution is to use a pin to remove the offending wires from the headers. Push down on the little tab while gently pulling and they come right out. Change the order and insert wit

How variable does it need to be? Could the Raduino drive a relay to switch between the board's power level and a higher voltage source by a software menu satisfy your need? Or are you looking for more

A relay to select the board's power source (12 or 13.5v) or an alternate power input (24v or a variable input) as the feed to the finals, potentially with the system reading the voltages and the softw

Gene, What frequency did you test on, and did you try other frequencies? It turns out my Bitx40 shows different output levels depending on the frequency across the 40m band, maybe your board has the s

Raj, Could you suggest a method for bypassing L1-L3? I'm not sure how I would do that with any temporary change, any approach I can think of would be permanent and then attempting to reverse the damag

#bitx40

Bottom line up front: I am having a problem with my Bitx40 where the power output decreases as I increase my frequency across the 40m band. I completed all of Allard's 1.27.3 mods, plus RX/TX lights,

Or go with a metal military ammo can for really rugged construction. The lid even easily detaches, just open and slide sideways until the hinge pins disengage, so it wouldn't be awkward for shack use

Here's a better link to the actual blog post in question, the previous link is to the blog in general: http://bitxhacks.blogspot.com/2017/03/a-band-scope-for-bitx.html So excuse the dumb question, wha

Has anyone made a desktop capacitive paddle? I was thinking about a wood base filled with lead shot, but the difficulty of making the top half look "nice" and figuring out size/spacing/etc put the pro

Or crush the SMD with clippers, then remove each half individually with a small solder tip. John

I'm 36 and a chemical engineer by education (I'll also admit, I was not a big fan of my one electricity & magnetism class during undergrad), but a recent job change put me into the world of RF. Rather

Maybe use a cheap dongle and a power meter until you're confident in the switch?

Arvo, Very cool find, thanks for sharing! John

I think most would have the SDR dongle attached to the computer outside the Bitx's enclosure, so they could use the dongle with other antennas for different applications. I was going to run the coax f
