As shipped from the R.L. Drake Factory, the Drake 2B was a Ham Bands Receiver. Open crystal positions were supplied for addition crystals to cover 600 KHz segments of the shortwave bands. Nowadays it is impossible to find enough extra crystals to add decent coverage. So I built a DDS Synthesizer/VFO. The Drake is very sensitive and makes an excellent receiver.

The SSB De Luxe was Kraco's "Top of the Line" in the mid-1970's. By the time I got a hold of this pristine example in the 2000's a 23 Channel SSB CB Radio was pretty useless. I added a Tuneable VFO/Digital Readout that allows using the SSB De Luxe on the 10 Meter Amateur Radio Band.

It was a fun project that worked well...

I added the colorful LEDs too.

This is a great resource to check on band openings by frequency. It is also applicable to International Shortwave Broadcasts

I have my Dell Laptop connected to the Icom IC-M700 through a Mixer to facilitate Digital Modes. I tested it out this morning on 20 Meters FT4. I managed to contact a station in Norway and a station in Russia. I attached images of the contacts.

The interface requires switching from Transmit to Receive using a toggle switch. I will remedy this in the near future by either using an interface that I've already built -- a Darlington Transistor does the switching via audio transmitted from the laptop, or I will use an Optoisolator - which is preferable. The Darlington Transistor method is touchy to get just right.

I've included schematics for both methods in the attached images.

The Icom Transceiver is ideal for digital modes because it lacks a Tuneable VFO. Any frequency between 1.6 - 24 MHz can be entered and saved into a fixed channel. Digital Modes do not require tuning via the radio once set on an operating frequency. The fine tuning is done through audio via the computer. Change the audio frequency and you change the transmit and receive frequencies in small steps due to the fact that you are modulating the radio in USB (Upper Side Band). So changing your audio pitch raises or lowers the Transceiver frequency in small increments.

I will post more about this if interest warrants.

A 90 Watt AM/CW Transmitter, produced from 1959 - 1962 by World Radio Labs. The Globe Scout Deluxe sold new for $159.95, which is equivalent to $1,800 USD in 2026. This is a very heavy piece of gear due to a massive Power Transformer, Modulation Choke, and Power Supply Choke.

The RF Output tube is a 6146. It's Modulated by a 7027A (6L6GC) using Heising Modulation for 100% modulation on positive peaks.

This transmitter is in good electrical condition, although it will need replacement of the filter capacitors. The worst part is the condition of the front panel. I'm hoping to restore the front panel, avoiding repainting it.

The Audio Interface permits using professional microphones, through a Mixer/Equalizer and a Compressor.

Additionally, audio from a computer can be added, for Digital Modes such as FT8 and SSTV. A Gain Control has been added to the Audio Interface which allows RF Output at levels of 5 Watts to 150 Watts.

The audio is Balanced XLR up to the Interface, where it's converted to Unbalanced and directed through a 600:600 Ω transformer to the radio.

I completed the wiring of the new M75 Cobra Power Microphone, including modifying the M75 for enhanced low frequency response, and increasing the amplification factor to +30 db.

The new 6-conductor Mic/Audio Cable was installed with connectors that will facilitate different audio inputs.

The Icom IC-M700 comes with a mounting bracket, but no feet. It is drilled and tapped for installing bottom feet so I installed four feet.

A test transmission in the form of a CQ on 40 Meters LSB, at local sunset, was 15 db over S9 in Prince George, BC Canada. The distance is 580 Miles.
