Hi All,

Thanks for visiting my QRZ page.  Someday, I'll add some pictures, but for now a wordy description of my humble station will have to do. The picture import feature on QRZ is not friendly at all.  You can see an article I wrote for the Santa Barbara Amateur Radio Club website with pictures here;

My only radio for HF is a Yaesu FT-857D.  I mostly use this on 40 meters but I did recently make a contact in Missouri on 15 meters.  The antenna is an inverted V, each side cut to about 33 feet, fed with 450 ohm ladder line that is about 46 feet long.  The center of the V is about 30 feet high and the ends are about 15 feet high.  The ladder line is fed into an MFJ-969 antenna tuner using the Balanced Line connections. The tuner is connected to an RF sensing Tx/Rx switch (MFJ-1708).  The switch then directs the signals to an SDRPlay receiver when no RF is presented by the transmitter.  I run the SDRPlay receiver with HDSDR software under Windows.  The software defined radio provides a great panadapter for the Yaesu FT-857D and provides rig control for both radios so they follow each other.  When the PTT button is pressed the RF switch flips so that the receiver is yanked to ground and the transmitter is connected to the antenna system.  I also mute the audio on transmit so I don't have to hear the switching and other noise during the transitions from Rx/Tx and Tx/Rx.

I also dable in digital modes, mostly JT-9, JT65 and PSK31.  For digital modes I take the RF switch and the SDRPlay receiver out of the system and hook the Yaesu directly to the tuner. 

My station includes a RadioShack Pro 95 Scanner for scanning local law, fire and forrest service radio services.

A handheld (Wouxun KG-UVD1P) on a home-made copper slim jim antenna for a nearby 1.25 meter repeater that is linked to the repeater used by my local club's nets in Santa Barbara. If you google earth my location, you'll see that there is a mountain ridge separating me from Santa Barbara.  So, that little handheld is my link to the local nets.  I have access to other repeaters in the area, but they aren't linked with the club's main repeater for nets and the like. 

I do run a swap-net for my local club every other Wednesday on 224.08 MHz.  On those nights, my little handheld can overheat and shut down.  So, I built a heatsink and fan combo to keep it cool. You can see an article about FrankenHT at the Santa Barbara Amateur Radio Club website here;

I have a mobile (Wouxun KG-UV950P) for 2 meter and 70 cm FM.  This radio is connected to a tri-band gain antenna from Comet.  I don't remember the model number but its the one that covers 144/220/440 and is about 10 feet tall.  I got the Wouxun radios because I do have a need for two commercial frequencies where I live and these radios transmit out of the ham bands.  In addition, they are packed with features and of decent quality for the price.

I also have two Wouxun KG-UV8D hand helds.  One of them I hook up to a 30 watt amplifier for 2 meters and hook it to a ladder line SlimJim made for 2 meters.  The antenna is then hoisted above my walker using a telescoping mast up to about 17 feet attached to a 6 foot fishing pole as a light weight tensioner.   A canvas tool bag, sown under the seat of the walker holds the 12 volt battery and amplifier.  I added two cup holders and a couple of other bags with velcro or zip-ties as needed for additional capacity.   Insert small pictures or links to pictures here:

Makes a great platform for a rolling radio station for the various events that SBARC provides communications for during the year.  We provide comms for marathons, bike races/rides, endurence runs as well as the local Fiesta Parade.  Following is a link to the 100 mile run through the mountains that we work each year;
