Novice (WN2FXZ) at the tender age of 9.

Tech Plus (WA2IOI) from the late 1970s, had to go to the federal building in Philadelphia and take the test from the scary examiner and could not get 13 WPM. Used 2M off and on.

Finally shamed into upgrading to General then Extra by my friends a few years ago. I am an Electrical Engineer, working on Audio and Radios, so there was no excuse except procrastination for a few decades.

Vanity Call W7MLG.

Finally set up an HF station and have been having a great time.

I built a stand up / sit on a lab chair Ham station and workbench. Recently set up the workbench for SMT Soldering and Rework.


The Ham Station:


The SMT Workbench:


SMT Soldering Tools:

Metcal Irons and Tips, OKI Hot Air Pencil (got on Craigslist and Ebay). If you want to do SMT, Metcal is the way to go in my opinion. Amscope 10X Microscope to make up for my ancient eyesight.

View through Microscope (0603 CAP Pads and 0.5 mm pitch IC):


SMT Reflow Oven:

Here is my Reflow Oven.



Kenwood TS-590 that I have added a Clifton Labs Z10000U buffer amp after the antenna switching, filtering and first RF amp to provide an output to an Elecraft KX3.

The Elecraft KX3 can be used alone or, with the output of the buffer amp, as a secondary SDR receiver on the same band as the TS-590. I can also listen to two frequencies in the vicinity of the primary frequency on the TS-590 to help me with pileups. 

Elecraft PX3.

Two LDG tuners 600W and 100W.

Elecraft KPA500 Amplifier.

Perseus SDR

Homebrew switchable 4:1 or 1:1 balun.

Homebrew audio interfaces to the rigs.

Xonar U7 192 kHz 24 bit audio inteface from I/Q output of the KX3.

300 ft long horizontal loop in trees around my property.

HRD and HDSDR software to run it all, all radios and HDSDR are all synced, so changing the frequency on on the TS-590 changes it on the others, and clicking on a signal on HDSDR tunes the radios to that frequency. I can also add N1MM to the mix simultaniously for my pitiful attempts at contests.

Three Monitors.


Audio Stuff:

Behringer UB-1622FX-PRO Mixer

Behringer DEQ2496 Audio Processor

Blue Yeti Pro Mic

Koss headset

Heil Proset 6

Noname computer Mic/Headset

The mixer and audio processor have some learning curves to them, but they are very flexable.

I can adjust the audio anywhere from "super compressed screechy DX" to "radio announcer".


Boat anchor test equipment is gone, no more 608D to keep my feet warm.
