PH2LB shack on the internet.

Got my QCXmini kit from QRPLabs and finished it. So I added a complete building report (incl designs for the tilt-feet) on this page. 

A few owners of the new NanoVNA H4 have requested me if I could re-design the PCB so male SMA edge connectors can be used to directly connect the adapter PCB to the NanoVNA H4.  For a while I holded it off, but recently I got my hands on a used NanoVNA H4 which I'm very happy with because of the bigger screen (yes my eyes aren't getting better). I started to use the H4 and wanted a dedicated adapter for it. So I measured  my NanoVNA H4 and it has a distance of  39.5mm and comments from other OM's indicate that it's quite constant +- 0.1mm. 

So I made a copy of the original design and changed the board layout to fit our needs.

I have added 2 pages to the Tools and parts section of this website. 
A rebuild of the K7QO noise generator and a new Dual tone audio oscillator

For RF applications, one of my favorite ways to build is the ManhattanStyle  and I have build a lot of these circuits in mint tins.  One thing I'm always  struggling with are the  9V batteries holders and on/off switches. So I 3D designed and printed this 9V battery compartment with room for 1 or 2 common cheap PCB push button on/off switches (they come in lock and momentary versions).  continue reading . . . 

Recently I found a page which described Roy, W7EL, Lewallens Simple & Accurate Directional Wattmeter as it was published in 2/90 QST.  Searching for more information I noticed that W1REX - QRPme also has a updated version of this Simple & Accurate Directional Wattmeter.

I re-ordered the website to have a special kitbuilding section. Check it out : link.

I added a new for sale page on which I list left-over PCB's. These PCB's are sold at cost price (excl shipping).

As of 30 Juli 2020, I'm starting to sell my kits and assembled products on TIndie to see if that works out for me.

Check out my store : 

Book the weekend of August 8 and 9 in your agenda for this event.

When people buy one of my PCB's, kits etc. I ask then if they send me a picture when they build it or using it. Below you find images some OM's send me.

So check out the Customer Gallery.
