No problem, just some slight re-configuring and burnt fingers lol

That's great, if you build the new schematics pdf, the parts list can be updated. I've done well so far with the existing list, but with the missing info, I couldn't verify it while building my list. That single IF Module page is a huge help.

Thanks again : )

The inductors you refer to (L1 and L4 on the IF module, and L1 on the RF amp) are chokes to keep RF out of the power supply. Any value over the 9.5μH shown in the old schematics will work (even better) for that purpose. As finally implemented, these are the 22μH inductors you mentioned, and they're not hand wound. They're epoxy-dipped types that look like fat resistors. I tried to minimize hand winding as much as possible, and manufactured chokes are a good way of doing that.

The updated schematic for the IF module shows the shunt capacitors for the xtal filter starting as 68pF. Parallel caps can be used to narrow the bandwidth. The newer schematic shows the values for the two impedance-matching L-networks at each end of the filter (L2/C11 and L3/C20) as 5.1μH (on T50-6 cores) and 220pF (same for both ends). You may find you need to fiddle with these values to get a flat (unrippled) passband. 

Please  don't hesitate if you have any other questions.

I'm very close to finishing the receiver portion, but am a bit confused about the inductors listed for the RF amp and IF module. 

The schematics on github show three of these inductors as 9.5uH, and does not label the two matching inductors on the IF module. The IF module schematic is also missing notation for many capacitors. (I made some assumptions here based on the capacitors parts list and other posts)

I thought the three 9.5uH inductors were expected to be hand wound, but then I realized I have a pack of (5) 22uH inductors from the parts list (which is way too many if the first three are hand wound)

I was hoping you would be able to clarify the schematics for the RF amp and IF module?

Thank you!

Ty!!

I've just started working with this project and believe there are two parts missing from the parts list. (there may be others but this is what I noticed so far)
On the Digital VFO/BFO module, I don't believe D3 or R5 exist on the parts list. Did I miss them?

Please leave a entry about your progress, troubles and successes with the kit.  I just bought a complete kit from a fellow who decided to not assemble it and plan to start on it soon.  I would be very interested to read about your experiences.

I have put together kits in the past starting with a Knight Kit from Allied Radio back in my high school days and lately have done a couple from ORP Labs.   I am basically a QRP guy but also have a 100 watt system and a 4 band vertical antenna.  

I suppose by now that you have discovered the github location of the files about the PSSST transceiver.  Parts BOMs are there as well as schematics and some basic assembly drawings.  As stated this kit is not for beginners and I am thinking that it will be a valuable learning tool to work with.  

Thanks for posting and please continue.  The group at groups.io is full so no newbies can post there but it is worth reading the posts that do exist.
