An update to my post from June 4 ( /g/BITX20/message/27601 ) . Turns out the USB cable I was using was NG. Found another one in my camera bag and when I connected it between the

Look how much better it is now with a KNOB!! One of my friends at Goodwill felt sorry for me, sprung for the cost, and sent over a volume control knob... Jack, W8TEE To: [email protected] Sent: Friday,

Hello Allard, A big THANKS for your efforts and time to keep improving the bitx40 software, it gets better every time. I use my bitx for cw only and think you did a great job adding the right set of

I think Q13 is alive and well. ?I get DC voltages as well as great drive, but only if I inject a signal (7.2MHz) after the mixer or any where like C43 or C6. I will make that modification though.

That wooden case looks GOOD! Jeff

Wayne, If scratch building, you might take a look at the uBitx as well: ? ??http://www.phonestack.com/farhan/ubitx/ubitx.html ( http://www.phonestack.com/farhan/ubitx/ubitx.html ) ?

Opps...forgot the knob! Well, like I said, it's not done yet, but you can sorta get the idea. You can see a flush-mount speaker on the top, and the 3 "CW message switches" on the right-front top of

Thanks very much Arv.? A very comprehensive reply, thanks for taking the time. 73's Wayne VK6EH

So you're telling us the thing that makes all those fancy rigs so expensive is the volume knob? :) I am only waiting on the buck converter to show up to put mine together.? Thanks again for doing the

Our hamfest is this weekend and, even though it's not done yet, I'm taking my BITX40 (see picture) to show you don't have to be rich to have an SSB transceiver. Jack, W8TEE

I found a semi-kit on EBay for the WA2EBY amp. Uses IRF-510's for finals and puts out 40 watts of power for 1 watt of input with 28 volts DC power supply. How hard would it be to reduce the power on

WITHOUT Headers!

Glue a piece of black screen on the inside and install a chrome computer fan cover on the outside. Looks great! Steve kb1chu

It is easy. Just cover the inner surface except the grids. There ai put a piece of grill sticked with melting glue pistol

I just got 3 of them cheap. They are a little different than the one I bought for $20. They come WITH Header pins. I have lots of them, so no big deal. They also have the tiny mini USB not my

I know it won't line up with my PCB, but if you're going to get one, at least save yourself some grief and get the one with the USB connector so you don't have to mess around with the SCR link: Mega

Pin outs are different, they are "clones". I have ordered bits and bobs from Aliexpress for years now some items are total crap and some are the same or close to what you get here. The clones do work

Also check Q13 (in the TX chain), it can get zapped by strong signals when in RX mode if you haven't added the 1N4148 protection diodes. See post /g/BITX20/message/25062 (

Not quite sure where C71 came into it here, I had an apparently intermittent short under C107 (I assume hfsigs verified it worked before shipping). ?C71 is an AC short to ground for the VFO, so we
