East Side
Updated 18-Sep-2025
| This operating position is actually
attached to the two station setups labeled North and
South Side, shown elsewhere on this site. If you
would, consider this position as being the bottom of a
u-shaped desk arrangement with those two aforementioned
desk setups. Lower Shelf: Yaesu FT-726R triband VHF-UHF radio covering the 50MHz/144MHz/432MHz bands. This is my VHF/UHF SSB/CW station. On 2 meters I have currently worked over 35 states. Any amplifiers on these bands are all various solid-state brick amps. Desk Level Shelf: This is referred to as a Kenwood 8-Line. Most of this equipment is from the later half of the 1970's. Consists of R-L, the Kenwood TS-820 HF transceiver and next to it the matching R-820 receiver. This later pair can be operated in full transceiver mode with the TS-820 working as the transmitter and the R-820 as the receiver. This is probably my most advanced receiver in the shack. This R-820 is fully decked out with all the available IF Crystal Filters. What makes this receiver special is it has adjustments for IF level Notch Filtering, Passband Shifting and VBT (Variable Bandwidth Tuning). Essentially this receiver can remove just about any surrounding interfering signals residing near the desired signal you are receiving. Kenwood used the exact same front panel aluminum castings for the TS-820 and R-820, but as expected their knobs and switches serve different controlling functions, in most cases. For an purely analog receiver, exception for the digital frequency display, I have never used another receiver with the versatility and signal processing capability of the R-820! Rounding out the Kenwood line are the two SM-220 monitor scopes. One is connected as a frequency domain Panoramic Display (BS-8 Option) which is essentially a spectrum analyzer to display the band around the current listening frequency. This Pan display allows you to view the band activity around your received frequency (+/- 100KHz) or a closer in sweep to view the received signals spectrum (100hz min). Outside of a modern SDR (Software Define Radio) with their spectrum displays this was not a common item in the 1970's, or prior. The second SM-220 is connected to the TS-820 RF Output, to monitor its transmit time-domain output waveform. As a speaker for both the TS-820 and R-820 I use one Kenwood SP-520. On the left side of this position is my ICOM IC-202A 2 meter SSB/CW low power transceiver connected to a Tokyo HY-Power HX-240 HF-Transverter. I talk about this elsewhere on my site. This little VHF transceiver becomes a full (Pre-WARC) 50 watt HF SSB/CW station utilizing the HX-240 to move it's operation down to the HF bands. Above the East Side operating position is a shelf that contains two antenna matching unit.  L-R: The Millen 92200 KW Transmatch is used with coaxial line antennas when needed. Next is the Johnson Matchbox Junior 200W tuner that is used for ladder line feed antennas. Both tuners are for HF work only All my antenna transmission line feeds are located behind the wall. A wall mounted coax switch is used to select one-of-six antennas plus one-of-six rig positions. The knobs for the antenna switch are located on the wall below antenna tuner shelf, but all the actual coax cable connections (the switches themselves) are on the back side of this wall - out of sight! Only the final coax feeds enter the room at a point nearest the radio they support, where they are not visable to the operator. |
