Thanks for the contact! (Yes, it's a vanity "CW" call sign! Ex K5HKR.) And the "handle" is JB not Jim.  smiley

(Pictured: SoftRock RXTX for 30/20/17 - 1 watt SDR QRPp that got me back on HF in 2010 and logged several 6,000 miles per watt contacts - Croatia, Serbia, New Calidonia, Australia, New Zealand to name a few.)

Please consider joining one of our NAQCC QRS nets,  http://www.naqcc.info/cw_nets.html  

or our "FRN" FarnsWord CW skills building "social" net,

     Sunday at 20h00 PDT on 3,574 (03h00z)

     Monday at 20h00 PDT on 7,123.5 (03h00z)

The FarnsWord net, however is not QRS - it is a ~20 WPM "FarnsWord" Method - base speed 20wpm with extra space between words rather than between the letters. 

KR5RR/M (Mobile) –

(2015-05-15) Mostly working /PM (Parked Mobile) at twin GKids Baseball or Soccer games and tournaments, or at Karate lessons. running a battery powered 20w to hamsticks. Very tentatively (carefully?) trying CW while driving [Thanks Dick!].

 (2015-03-08) Getting good results with a 4" magmount on rear with a short braid ground just inside the hatch lid - very convinent for changing tap settings on MP1 coil on 15/17/20m.

(2015-02-15) Recent double braid grounding of the hamstick roof rack mount to the roof of the SUV has yielded some great signal reports on 20m. Thanks to all for the excellent QSOs! 

(2014-12-15) Starting to get into this /Mobile thing with either FT-817 or FT-857 and hamsticks. Took about six months to get to where I can consistently and confidently make contact, RF image 'ground' is the key. PS: I believe hamsticks have gotten a bad rap - work great for me. 


   FT-857D, FT-817ND, VX-7R, marine mobile (kayak), pedestrain/mobile, and auto/mobile with hamsticks

   3 SoftRock RXTXs, QRPp 1.0 watt on 80/40, or 30/20/17, or 15/12/10, w/ZM-2 & dipoles (PSK31 only).

ANTENNAS: Simple wire antennas. Thanks primarily to W4RNL, L. B. Cebik (SK), I've re-discovered twin lead (reliving the 60's!) and balanced wire tuners. So, by abandoning single band coax fed dipoles, the current antenna count is down to three 300 Ohm Twin Lead fed doublets for multiband operation:

- 44 foot flat top doublet running NW/SE, 30 feet high

- 67 foot flat top doublet, running N/S, 33 feet high

- 135 foot flat top doublet, running N/S, 35 feet high

- 135 foot, inverted "L", 35' vertical, 100' going up into a 60' high Eucalyptus tree, mostly for 160m

Use a MFJ-974HB Balanced Line Tuner with 300 ohm twin lead that goes SWR nuts when it rains. And a 2m vertical dipole, fed with 50' of very lossy RG58. All are up on lumber yard masts (2x6, 2x4, 2x3, 2x2). When QRP, use a ZM-2 Z-match tuner - seems to be very little it can't match.

Portable ops while camping - antenna are everything. Some success useing a different length vertical wires with four 20' on-the-ground radials. However, what is working great (best) on 40/30/20/17/15m, is hamsticks on the SUV. Not quite "tent" or "picnic bench" stuff, but it works for me.

OPERATION: Almost all CW with some digital modes using SignaLink/fldigi on 10m - 160m when I'm trying the digital nets. Most of the rest is FM, on 2m/70cm with a little bit of SSB in Contests. Not into certificates or awards, but happy to hard copy QSL if you want one - no return postage needed. (Don't do eQSL or LOTW.) Get a kick out of the SKCC, NAQCC, Flying Pigs and other two hour sprints.

#8118 SKCC - Straight Key Century Club (original J-38 from my novice days, of course!)

#5604 NAQCC - North American QRP CW Club (NCS for 40m FRN net)

General station 1959

Started really young with a Boy Scout Radio Merit badge then Novice (~1957? or 58?), & General. Still in High School, earned a 2nd Class Radio Telegraph to work for my Merchant Marine Captain uncle, but that only lasted one summer cruise. While in college earned a 1st Class Radio Telephone with Radar and was a part time, late night, associate UHF TV station engineer in Birmingham. Fresh out of college, landed my dream job as a Field Engineer for Collins Radio Company, Dallas, TX. However, as time passed, working on really big VLF transmitters (>500kw) with really long antennas (35,000' vertical and/or 7 mile long horizontal loops), controlled by really expensive computers, kinda burned me out on radios (check TACAMO on Wikipedia). Turned my hobby into my vocation - ruined my hobby. I went QRT from ~1971 to 2010. A woman kinda helped with that, also.

Funny thing, ocean kayaking and VHF marine radios got me back into ham radio! Back on the ham bands in early 2010, first VHF/UHF with a VX-7 HT, then HF with the 1 watt SDR RXTX SoftRocks (30/20/17 tri-bander pictured above). Had a lot of success with the 1 watt QRPp rig on 17m and 30m with dipoles, working 37 states and 17 countries on CW and PSK31 - did 6,000 miles/per watt many times to Eastern Europe & Asia Pacific. Got the FT817 (49 states [what's up with Delaware?] & 113 countries), and after a year of QRP, built a 30 watt amp. Just before Field Day 2013 got the FT-857. Oh, and finally got Delaware, QRP CW and digital.


When I turned 15 and got my driver's license, had to choose between buying a car, or a Hallicrafters SX-117 receiver: ham radio won - and I've never regretted it.
