This is the Owners manual that I have thrown together
The transmitter and supplied key all set up!!

This is the schematic of the transmitter.. but note that I replaced the 47k grid resistor with a 2.5mh choke to get a chirpless note.

I never put any labels on the transmitter, so this should help get a grip on what the knobs do. The standby position automatically switches the antenna to the receiver while at the same time connecting the transmitter to an internal dummy load. The built in dummy really helps getting this transmitter dipped plus it provides a crude but effective way to spot the transmitter. The plate control dips the plate meter. The crystal in this photo is provided.. you will find it in a bag with the four receiver crystals. I also provided a BNC cord to connect the transmitter to the receiver, PLUS I provided a real nice hand key all cabled up ready to plug into the transmitter

The transmitter has two BNC jacks. Connect the receiver to the one shown. Just like the receiver, I removed the tubes for shipping so the huge labels I annotated into this photo should help identify what goes where.

The regen pot on the front provides an ultra smooth regen point. I also provide a window in the side of the chassis that allows access to a coarse regen control to give more regen range. When listening to SSB, I found it nice to give this radio as much regen as possible to keep the signal from "pulling" the detector. It takes some practice to get the best results but it is always fun!

The receiver has a 75 KHz tuning range that can be expanded to approx 150 KHz by connecting the two points shown on the photo below. The reason the tuning range is so small is that I designed this for use in the CW band. I believe the dial is currently calibrated for the bottom of the 40 meter band. I provided four crystals (in a bag with the transmitting crystal). One for the cw and one for the ssb section of 40 meters.. one for 20 meters and I think the other one is for the 49 meter short wave band. I removed the tubes for shipping, so this picture should help identify where to re-insert them. I hooked this radio to my computer sound card via the RCA connector on the back. The Dial calibrator allows you to select the section of the band you want to monitor.

This picture shows the coarse regen control that is accessible through a window on the side. Also visible is the dial calibration capacitor

The power supply is connected to the receiver with the connections shown below. I used to have a separate (AC) filament line, but when I converted the filaments to DC, I just tied one end to ground. That is why there is now two ground connections. The bonus is that there is no AC hummmmm.

Here is a closer look at the rest of the receiver back.

This is a close up of the connections on the back of the receiver power supply

This is the receiver schematic.. I do not have the power supply schematic handy but it is very traditional and easy to figure out by just looking at the components. It uses a VR90 tube to give it perfect B+ regulation. The filament voltage is rectified and filtered with a monster size computer cap..
