I followed the directions exactly. I know the oddity you're speaking of. The brown wire from the raduino connects to black on the board and the brown wire from the board connects to red. I did that

Ok, it sounds like the Raduino isn't providing a signal. Make sure it's correctly connected, there's a wiring color oddity between the two cables. I'm also assuming you're working on a BitX40 and

The PA voltage is going through the switch as well. I measured from the DC plug to the base of the positive that feeds the PA. It does double when I click PTT, but that's it. I'm set on 200ma so I'm

The idle current you adjust is measured from the PA voltage and the on-off switch doesn't switch that (unless you hooked it up to the switch as well). Also at 2 feet from the receiving rig, the dummy

I'm very distressed right now. My 9 year old asked for one for Chanukah built inside a lunchbox. She studied and got her general just so she could have it. She's worked really hard and I've already

Take a look at the NESCAF. I have 3 of them, one in a stand alone case with a zero beat kit, one in my Bitx40 and one waiting for a ubitx hihi. I just love them for CW and with the Bitx40 it can help

Same with my boards. Looks like there are reverse flow protection diode built in to the 7805. Raj

This looks like the adaptor I used to fix a movie camera tripod head to a camera tripod stand

I ordered on the 10th Dec (Australian time) and I got notification at 2:12 am AEDT today (17th Dec) that the package had been posted.? Tracking number does not yet reveal anything, but that is par

I plan to add an inexpensive audio filter on the output. Note also the the frequency you see in CW with the uBitx will differ from the frequency reported by commercial rigs that take into account a

No worries, Vince - thanks very much! Andy

Sorry...the file names didn't make it into the post.? The top picture that could be a glove is with the 4:1 transformers installed.? The bottom one with the much smaller ripple has no matching

Thanks Ashhar.? I'm enjoying the learning. :)? ?I have read W7ZIO's paper a couple of times and am understanding more of it now that I'm melting solder and getting more comfortable with DISHAL.?

Many years ago I talked my Junior High shop teacher into letting me build a Heathkit Tower (aka Benton Harbor Lunchbox) in place of his lame project. It was a nice little rog for the time. Over the

Ignore that. Wearing the wrong glasses and thought you were looking for attenuators, not terminators. Vince.

I don't have a URL handy, but if you google "pi attenuator" you should find the tables of what resistor combinations to use for various levels of attenuation. There should also be a calculator or two

andy, this a terribly confusing topic. let me attempt it as best as i can from the phone. a filter can be driven and terminated with any impedance without the rf police turning up at your

Greetings RF Gurus - a noob has ascended to bother the masters. ;) Would someone please point me to a schematic or other resource that would help me determine the correct resistor values so that I

I also ordered on the 10th and had not heard anything as of last night so I emailed Ashar. He said it shipped but he's a little behind updating the statuses.? -- John - WA2FZW
