The shack was beginning to look like a disaster area with everything piled on top of everything else and no room to walk around much less do any projects in there so I decided to clean it up and clean it out. I figured it was time to change the layout as well.
The Heath gear has been moved from the top shelf on the operating desk to a separate stand-alone old stereo cabinet. The HR-10 receiver is on the bottom. It is currently not working as it had some undocumented modifications done to it in the form of IF and audio filters that were removed. I need to find time to get it on the bench and do some signal tracing. When the Heath is in operation a Kenwood R-1000 is used as a receiver. Above the HR-10 is the DX-60B AM/CW transmitter and HG-10 VFO. The DX-60 microphone used is a Sennheiser MD-421 which has a built-in five position roll-off filter controlled by a ring near the connector. This greatly changes the sound quality from sharp to soft and mellow. The microphone preamp is a Radio Design Labs STM-2 active transformerless balanced to unbalanced amplifier. I also have a Urei 527-A EQ that I may use depending on the overall sound quality and frequency response from the MD-421. The oscilloscope on top is a Hitachi V212 which is an older 20 MHz unit and is used for watching modulation of the DX-60. Since I only use it on 80m and possible 40m the 'scope is fine for this. The gear is simply in the cabinet for now and not wired up yet.
The main operating desk in the shack. Main desktop surface from L-R is: 100 watt Dielectric dummy load for testing,Kenwood SP-820 external speaker with filters. On top of the speaker is the controller for the Ameritron RCS-10 remote coaxial switch. To the right of the speaker is a Kenwood AT-230 antenna tuner with Yaesu FT-857D on top and a LDG FT-METER above. Next is the Kenwood TS-820S transceiver with two Diawa HP-801 meters on top. One is a 2Kw model and the other is a 3 Kw model.The 2Kw meter will be used with the Larcan 6m amp and the 3 Kw meter will be used with the home brew 3CX3000A7 amplifier I hope to eventually get built. To the right of the TS-820S is the VFO-820 external VFO. The microphone is an MC-50.To the right again is a VFO-520 external VFO that goes with my Kenwood TS-520 which is currently out on long term loan. The empty cabinet on the far right is from an old Heath monitor scope. It will become the control head for the Larcan 6m amplifier which will be mounted in a vertical position under the far right side of the operating desk.
On the far left again on the shelf there is a Ranger 2950DX 10/12m mobile radio that was used as a 10m IF in a 2m transverter project. It now serves to monitor for 10m FM activity. Next is an Icom IC-2000H 2m VHF FM transceiver. On top is the controller for a CDE Ham 2 rotator. Next is a Tektronix 465A 100MHz oscilloscope with a Wavetek 4101 AM/FM modulation meter. Next is an MFJ dummy load and a Ten-Tec AT-227 manual antenna tuner. Next is the Kenwood R-1000 receiver and a Radio Shack DSP unit on top. The control unit for the Yaesu G-2800DXA rotator is next followed by a Tripp-Lite PR-40 power supply which powers the FT-857 and shack accessories.On top of the PR-40 is a home made voltage and current bridge with distribution busses on the rear to feed various pieces of gear.On the far right is a Motorola 25 amp power supply that feeds the mobile radios in the shack and a spare Stabylex 7 amp power supply. Not seen is a 50 volt 60 amp blade server power supply that is to power the Larcan amplifier. It will be mounted under the desk to the underside.
Overall view of the shack operating position. Under the kick space can be seen the Larcan amp with cooling fans installed. This will be installed under the desk on the far right of the file cabinet.
