Some shots from my laboratory and associated library

Fletcher's Circuit Cellar !!!


- The Main Ops Centre photo 1 ( 100k ), this is where I do the tuning and prototyping stuff

- microwave source corner photo 2 ( 96k ), 2 - 12 GHz, 1 W and a water cooled 9 kW, 3.4 GHz load on the table...

- maintenance corner for CB's & other low tech stuff photo 3 ( 93k ), apprentices only !

- frequency synthesizers, modulation analysis, transient analysis, etc. photo 4 ( 92k )

- Inventors Brainstorming Corner photo 5 ( 78k ), a place for a relaxing cuppa tea or coffee

- the Drawing Board photo 6 ( 75k ), the PC and drawing table for documentation

- part of the library photo 7 ( 86k ), data books & sheets, notes and memos etc.


Some of the feedhorns ( 70k ) stashed away to wait for the snow to melt and also spare time. From left to right:


- 1.3 GHz RHCP/LHCP low ellipticity feedhorn for low f/D EME dish ( made by OH2AXH )

- 5.7 GHz RHCP/LHCP/linear feedhorn for low f/D EME dish ( my own design, made by OH2AXH )

- 10 GHz modified Ku-band feedhorn for low f/d EME dish, linear polarisation, servo control ( my own mods )

- 10 GHz reference horn for the AMSAT-OH 10 GHz P3D satellite payload, RHCP, low ellipticity ( design OH6DD )

- another 10 GHz P3D reference horn, RHCP/LHCP ( design OH6DD )

- 3.4 GHz linear polarisation horn, servo controlled, for low f/D EME dish ( my own mods )
