Shack-Wide NewShack2 CALF-3CPO-HW-8
Once in a lifetime event – The bench is clean! 2016 Shack Upgrade The happy trio – HW-8, CALF, and 3CPO

The gear consists of an Icom IC-725 and MFJ 949D tuner/meter as the primary HF station with a Bencher and 3CPO for CW.  The old TRAC keyer still works but mostly retired now.  The main antenna is a simple 40M bowtie dipole which works pretty good on all bands.  Lately my Heathkit HW-8 has taken center stage pretty much replacing the IC-725.  Since my first HW-8 there is now a HW-7 and another HW-8 for camping.


The 2M primary station is an IC-251H with killer audio and RF output.  For Satellite and ISS work a Yaesu FT-290RII and Kantronics KAM fills the bill.  Yes, you can work the Space Station on just a watt or two and a simple vertical antenna!


When home-brewing and repairing we also use some fairly older equipment.  Heathkit IG-1271 signal generator, B&K 512MHz frequency counter, Philips 100MHz scope, Autek WM-1 RF/SWR meter, Heathkit IM-1210 DMM, Ramsey COM3 service monitor, Bird Wattmeter (that I always want more slugs for!), a few handheld DMM’s, my Digital Dummy Load, bench vise, and of course a Tenma solder reworks station.


Not pictured of more old equipment I pull off the shelf from time to time to play with.  A Kenwood TS-520 (under restoration), TS-530, Heathkit HW-16, HW-7, 2nd HW-8, HW-101 (under restoration), and my first rig an old Hallicrafters HT-17 (also under restoration).


Thanks for stopping by and 73!
