About my Call Sign & QSL Card...

K-9 Sylvester (Sly)

I have been a police officer for 23 years. 10 of those years I spent with the best partner...

Sylvester's story starts in the soviet republic of Georgia (former USSR) in 1991. After being washed out of the military he was sold to a US vendor for police service and shipped to the USA. My Department purchased him in 1992 for $2,500.

Sly and I completed Police K-9 Training in April 1993. We worked midnight patrol for seven months and were the first K-9 Team, in my department, selected to be crossed-trained for criminal apprehension and narcotics detection.

During our 10 years on the street we were responsible for more than 300 criminal apprehensions (some resulted in bites!) Over 1500 narcotics searches and countless misdemeanor arrests. Resulting in the seizure of hundreds of thousands of dollars in cash, property and drugs.

Sylvester was retired from police service in April 2002 as I continue a career as a detective in Computer Forensics.

Sylvester passed in January of 2003.

This call sign is my way of keeping a part of him with me and remembering his service to our community...

Vintage Rig Profile - The Drake Twins

From K9SLY

Here is a little background on my first HF station.

The Drake company was founded in 1943 by Robert L. Drake in Ohio and manufactured low pass and high pass filters for government and amateur radio service. After World War II, Drake began producing amateur radio gear. Many Drake receivers, transmitters, and transceivers manufactured from the 1950s through the 1970s are still in active use today by collectors of vintage amateur radio equipment.

The R.L. Drake Company produced the R4B as a refinement of their previous popular R4 and R4A models. The R4B covers:  3.5-4, 7-7.5, 14-14.5, 21-21.5 and 28.5-29 MHz plus ten additional 500 kHz crystal positions (with optional crystals). Modes of reception include:  SSB, CW and AM. The dial accuracy is and impressive ±1 kHz. Features include: PBT, Line out, Crystal Calibrator (25 kHz), RF Gain, Mute Jack, Speaker Jack, Anti-Vox Jack and Dial Lamp. This radio requires an external speaker. The R-4B will transceive with the T-4XB tranmsitter.

The Drake T-4XB is an HF amateur band transmitter covering 80 through 10 meters. Four additional crystal sockets are available for 500 kHz ranges from 1.8-30 MHz (except 2.3-3, 5-6 and 11-11.5 MHz). Modes include USB, LSB, CW and AM. Input power is 300 watts PEP SSB, 260 watts AM/SSB. The solid-state VFO provides 1 kHz dial accuracy. VOX or PTT may be selected.

The Drake MN-4 matching network matches 50 ohm transmitter output to coax antenna feeding with VSWR of at least 5:1. Frequency coverage is:  3.5-4, 7-7.3, 14-14.5, 21-21.45 and 28-29.7 MHz with up to 200 watts continuous. It features and integral wattmeter that reads forward power in watts and VSWR directly; can be calibrated to read reflected power. The rear panel features SO-239 jacks for input and output.

The Drake MS-4 external speaker features a 5 x 7 inch speaker for clear, rich sound. 11 x 6.25 x 11.6 inches. The black, all metal cabinet features four legs. This speaker comes with an audio cable wired into the speaker and which terminates to a male RCA phono plug.

Rounding out my Drake Station is an Astatic D-104 Mic. The D104 has always been a great standard in many forms of radio including ham amateur radio, cb radio and even commercial broadcasting. Astatic Microphone Laboratory was found in 1933 by two Amateur Radio Operators. The D104 Mic first sold for a little more than seven dollars. The D104 Microphone first earned it's reputation and popularity on AM Amateur Radio.
