Re: White NanoVNA-H Install Problem Help

Hi Chuck, I am not sure than an OTG adapter will solve your problem.
My understanding is that an OTG adapter is used with an Android phone / tablet
or a Windows tablet to create a standard USB port like on a normal PC to which
you can connect a device such as a thumb drive (aka USB storage stick).
I suspect that you may not have a suitable driver installed and that the use
of the Zadig program will help resolve this.

Re: QCX kit Filters Included

I just got a Rev 5 kit for 40M and it has one large bag with the PCB and a bunch of parts, another with knobs, some pots, and connectors, and a third bag labeled 40, which is the filter kit. Did you get the PCB bag??

I'm just starting my QCX kit inventorying parts. Ran out of gas  with so many individual R and C values to sort. Not enough muffin tins to sort them all now. Plan to hunt and peck as I build.
However, I have a question about some parts included in individual plastic bags in the kit. I have included a photo. Two bags labeled 20M LP filter and one labeled 20M bandpass filter.
The inventory of parts does not indicate parts in a bandpass filter bag but does show some parts in a LPF bag.
Is this correct?
Thanks

I recently assembled the KD1JV Dual Lever Code Trainer Combo.  The nuts were a b*tch to thread on in the space provided.  I used a small dab of solder flux on the threads.  Easy peasy.  The flux was immediately available and worked great.  GL.

Hi,

Most of our gear these days weighs a lot less than 125 pounds. Probably all of the gear with those tiny screws is light weight. I put the screw on the tip of my screwdriver pointed straight up. Gravity holds it nicely in place. I turn the equipment so the threaded screw opening also points straight up and then join the two:)

Just be sure to buy regular Blue Tack at the stationary store.

Don't get fooled and buy AudioPhool-Grade Isolation Material for Turntables. YES ! I was walking by a high end audio store and they had Blue Tack for sale for something under 30 dollars as isolation for the turntable from vibration! Hello Mr Barnum !

Anyhow, I much prefer the slab of marble my friend in university used under his Rega Planar Transport with the Vestigial Arm   :)

Hmmm, why did I post the message here?  8^(

I found this in another message I'd received earlier:

 <If you ordered an older model NanoVNA, with open sides, then you will need to use an OTG cable between the two devices.>

And that's what I have so off to Amazon to order one OTG adapter...

That's what I have always decided upon, but common convention in this part of the world
always referred to the hand you write with for some reason.

I find that strange.

But then, I write left handed, but do everything else right handed.

Great for CW, since I can keep the left hand holding a pen for taking notes, and the right hand for using the Morse key.

Maybe I was made for CW ;-)

Andy,

Dominant hand.   Very few people do not exhibit a dominant hand.

Took me a few years to train my left hand so I could do most things as well
as my right including writing, though that is poorly for lack of practice.  It 
was a combination of keyboard (musical) and building stuff that really
required three hands and good agility.

As to what way the coil is wound, mine is oddly upside down too and works
just fine.  That is despite being "right handed" I tend to wind toroids reversed.
Teh key with TI us maintaining the same "sense" relative to the two windings
going to IC4.

Doesn't the RX board have jumpers that need to be removed/altered

No TI?   How?
 
I've tested a version of T1 that omits the big winding just three of the 5 turn
windings and that performed well enough but I did encounter some BCI
from a 1200khz station that was easily eliminated by a simple high
pass filter.

Old hands, tiny screws, and a lack of patience

KI7MWA
 

How many times have I lost one of those tiny screws while trying to get them started in their tiny holes?  How do you do it?

My method is to jam the end of a wood stick into the slot.  I have a pack of cotton swabs on 6" long wooden sticks, for cleaning pcbs, &c.  On the really small screws I have to carve the end of the stick down a bit to fit into the slot.  Carve it down, jam the screw on, and voila, you have a 6" long handle on your screw.  Works best with other than flat-blade type screws.
