Robert, I have not seen my v6 go over 2.5amps on CW transmit.? I have not checked with digital modes.? 3amp power supply or better would be my recommendation. 73 Evan AC9TU

A nanovna for $40?can measure the impedance of a cap over a range of frequencies from 50khz to 1ghz. At some point the cap is self-resonant, and beyond that a cap starts looking like an inductor due

While I understand the rationale for the V6 board design, ease of assembly, the board design negates one of the best points of the BITX radios, the ability to easily try new things.? I REALLY wish

How small is really small? That Nano clone trick works with caps between 1pF and 1000uF. /g/BITX20/message/52471 Way better than the capacitance meter in my $20 DVM. Jerry, KE7ER

Hi All, What's the transmit current? What do you think about 2.5ah? What do you think the minimum power supply should be 3a, 4a? 73, . Robert, AG6LK

To measure really small caps, I've used a resonant circuit. You make up a coil of appropriate value and put it in series or parallel with the cap in question. Then hook a scope and an oscillator. If

I watched that 18 minute video so you don't have to. Here's my review:? ?? He has a lab full of really nice gear. His technique is to drive a 1v square wave from a 50 ohm source into the cap,

The SMD parts I get from Digi-Key and Mouser come in small plastic labeled bags. I just leave them in the bags and line up the bags in storage boxes. The labels have the value, working voltage and

Gerard: I would like to put a module that decodes the MORSE directly on a PC This is very hard to do well. It's not too hard to get one to decode the W1AW code practice sessions because those are

Thank you Jerry for your response. The basic question was what type of capacitors were on the filters at the output of the UBITX power amplifier. The answer is clear, and given by the creator, it is

If we are talking about storage, one that I use is coin envelopes and VCR tape boxes, that I have glued dividers in the width of the coin envelopes.? I expect VCR tape boxes are pretty rare? now

Hi, I just string my SMD parts, by type and value, on a wire like on a fish stringer (threading through the last hole in the strip) and hang them on my workbench peg board.?? Takes up hardly any

If you have a spare Nano clone for your Bitx40 or uBitx, then you have all you need to build a capacitance meter: /g/BITX20/message/52471 You can use the Arduino IDE serial monitor on

Hi, Since there is still the 3pin header there, like in the previous versions, that seems the obvious place to input the higher voltage.? I imagine he just placed a joining trace between the

Are you happy with it? A couple of Amazon reviews said it wasn't much good for caps. - Jerry KF6VB

bought one of these.... jim

The small jars remind me of a bacteria farm. LOL. Each one has its own method, my SMD being in strips, I keep them in plastic bags. It’s not bad and spring prices here:

My 12v 20Ah LiFePo4 battery weighs about 7 lbs. What have you found that would weigh half of that? Max KG4PID

Hello All, I am building a small linear amplifier to go with my uBITXv6. I got a tiny 70W RF deck from China - marketed as "100W", but that's only if you feed it 16V. Also a card with switchable
