From W9RCJ :”Finished the transceiver last night and was on the air this AM, made two contacts, one in PA and another in OK.  The Case is a Double Bubble gum container that I have been saving for years, waiting to put it to a good use. and I finally found one. ”The case measures:  4.5” X 2.875” X 1.375”

 

Editors Note: Great packaging ingenuity!, Even my non-ham daughter said “it is so cute”. HI,   W9RCJ adds that he has a shield for the VFO, but left it off for the photo. Great job!!!

From N8BKY:”I put a counter on it and watched her settle down in frequency. settled down in about 45 minutes and hasn’t moved the last hour. Getting about 1 watt of power now after a few start up problems with components and a bad 2N4401.I may put a120  pf silver mica in the VFO.  Other than the part problems it is far more than I expected in the little rig.  I added an extra jack for a cheap speaker. If I can’t make out the code from the speaker all I have to do is slip on the headphones and not miss anything swapping jacks”

 

Editors Note: My congrats and thanks to N8BKY for bringing part problems and drawing inconsistencies to my attention.  I believe they have all been corrected now. I too have noticed that after soldering together it takes quite a while for the heat to dissipate and for the rig to settle down in frequency.  Neat construction N8BKY and thanks for hanging in there.

Made His First Contact on the Rockless

From W4HH: Joe reports he got his Rockless on the air January 9, 2010 and made his first contact with WB4OFT who was about 260 miles away and gave him an S7 with S9 on peaks.  W4HH has set up his own web site where he gives good hints and details of building his Rockless.  He includes wise advice and warns of pitfall he would like others to avoid.  Check out Joe’s website at  www.w4hh.org.  On the left side of his home page click on “Rockless QRP Rig” and you can read all about his building experiences including his photos and future packaging plans. 

 

Editors Note: Thanks Joe. Your information should be very helpful to other builders of the Rockless.

Again From W4HH: Joe has hooked up a Small Wonders Lab “Freq. Mite” to his Rockmite to give him a   Morse signal readout of RF operating frequency.

Here is the connection and operation information from Joe:

 

FreqMite AF out: Connect one end of a 100K ohm resistor to FreqMite AF out and the other end of the resistor to Rockless U2 Pin 6/junction of R2 and C6

 

FreqMite RF in:  Attach a lead from FreqMite RF input to junction of Q3 emitter and R15.

FreqMite Ground and V+ go to respective 12 VDC + and ground.

FreqMite requires a normally-open pushbutton switch to ground to activate the freq counter. No jumpers on the FreqMite jumper pins

 

With these connections, when the button is pressed and released to activate the counter, the FreqMite sends three digits through the Rockless audio.  These three digits are the frequency minus the leading MHz digit.  For example, if the Rockless is tuned to 7035 the FreqMite sends 0 3 5

From K7HB:  John sent these photos of his finished ROCKLESS mounted in a retrofitted Christmas candy box that cost $1.50. John gave it a coat of black flat paint to make it look real professional. The box is

5 1/2” X 3 ¾” and 2 ¼” high, so he had plenty room to fit in his circuit boards and controls. He also added a Nor Cal FCC-1 frequency counter under a Plexiglas cover he fitted to the box cover.  John reports the counter uses little current, and displays the frequency without operator intervention, and has no effect on stability.  He measures frequency to within 10 Hz and it allows him to easily set the offset frequency.  John uses a G5RV at 33 feet and reports good reports from his ROCKLESS. John cautions to make sure you have good bonding between the ground plane on the circuit boards and the housing. He recommends fastening a bolt and nut onto the circuit boards, and then passing the bolt extension thru the housing to a second nut that secures the boards to the housing.  The photo at right is Johns’ complete ROCKLESS station with his “pound of steel and hacksaw blade” paddle.  Get more information from John at: drdorociak@gmail.com.

 

 Editor Note: Thanks John for a great report and innovative use of the counter which is a very useful addition to the rig.
