~ ~ ~ THE 2N2/XX NORCAL KIT ~ ~ ~

LET'S BUILD A MANHATTEN VERSION

Using the original NorCal Manual of the NorCal 2N2/XX 40M kit. Dont forget the Addendum either
This has been a desire of mine for several years ever since I saw the "Original" 2N2-40.
K8IQY Jim Kortage K8IQY is the kit designer and inspiration.

Here is a complete 22mb PDF file of this project.

After selecting a single sided 6" X 10"piece of copperclad substrate some prep work needed to be done.
An S.O.S pad and little bit of elbow grease and warm water yeilded the clean substrate you see. Next!
I polished the substrate with a 180 grit Fine sanding block. Then wiped the sanding dust off using
acetone which evaporates very quickly. ( REMEMBER Acetone is very FLAMMABLE ).The substrate
has a total area of 60 square inches.I wanted to leave room for controls and cable routing.
So I marked off a 3/4" border for those controls.

The component values are on the 40 meter B.O.M.and the appropriate schematic in Manual.

~ ~ ~ Power Protection ~ ~ ~

The first step in the manual is the power protection circuit. So! Let's go.
[x] Install diode D18 a SB320
[x] Install capacitor C87 a 0.1uf

In order to make any trouble shooting easier I'll try and keep the circuitry placement as close to the
manuals as possible. This includes highlighting the components on the schematic as they are installed.
and required tests in each section. Just like when you build the Kit.

This being completed I added a negative connection point.

TEST: Apply 12vdc to the board. With a DVM or VOM measure that more than 11.7vdc appears at the
junction of D18 and C87.

~ ~ ~ Audio Transformer ~ ~ ~

Because the Audio Transformer is the "Anchor" so to speak of the audio chain and
I'm atempting to maintain a certain "Spacial Relationship" to the original Kit.

I've mounted the transformer before the "Receive Audio Power Decoupler

~ ~ ~ Construction Manhattan 2M2/40 Complete ~ ~ ~

~ ~ ~ Final Testing ~ ~ ~


Using Elecraft DL-1 and RF Probe measured 10.59 which according to their power graph equalls 5 watts.


Using the NorCal Dummy Load and RF Probe measured 21.52 which according to their power graph equalls 5 watts


Using a scope set on the 5volts per division measured 15 volts.


Using an Elecraft W1 power meter measures 5watts on the 14 watt scale (yellow LED).

~ ~ ~ Final Adjustments ~ ~ ~

Now that the 2M2-40 is complete, we can go back and do some final tune up work to optimize the rigs
performace. The steps should be done again after installed in a case.

~ ~ ~ VFO ~ ~ ~

This step sets up the VFO to 100KHZ of band coverage and sets the low end of the VFO to match the low
end of the band. This calibration step requires either a frequency counter or another receiver capable
of receiving the VFO across its tuning range.

[x] Connect a speaker/headphones to the "SPKR" jack. Apply power to the board. Connect the fequency
counter probe to the top of R40. Let the rig and counter warm up for 30minutes before proceeding. If
using a another receiver for this calibration, turn it on and let it also warm up.

[x] Center the RIT potentiometer (R53). Adjust trim potentiometer (R78) fully counter clockwise.
Turn the VFO frequency 10-turn potentiometer fully clockwise. Adjust trim capacitor (TC6) so the
upper VFO matches the upper frequency 2,184.80MHZ for 40 meters (NOTE 2,184.80 +4,195.20 = 7,100.00 MHZ

[x] Turn the VFO frequency 10-potentiometer fully counter clockwise. Adjust trim potentiometer (R78)
until the lower frequency match the lower frequency 2,084.80MHZ for 40 meters (NOTE 2,084.80 + 4,195.20= 7,000.00MHZ.

[x] Since there is some interaction between these two settings, repeat these two adjustments until
both ends of the band are set to your satisfaction.

~ ~ ~ Receiver Front End ~ ~ ~

This procedure will optimize the receiver sensitivity. With the receiver operating, apply a mid-band
signal to the antenna connector using a signal generator ( the NorCal S1-S9 generator is recommended)
set for 50uV or less. As an alternate, attach an antenna and find a moderatly strong signal. The VFO
should be tuned to center the signal in the pass band. Beginning with trim capacitor TC3, peak TC3, TC4
and TC5. Repeat this step a few times to obtain the loudest signal under these conditions. Reduce
the signal level to 1uV and repeak the peaking process.

~ ~ ~ TxLo ~ ~ ~

In this step , we will match the transmitt frequency to the receive frequency. With the rig transmitting
into a dummy load, adjust the LO trim capacitor (TC10) to match the tone that is heard in the receiver
when a CW signal is being received.

~ ~ ~ Transmit Strip ~ ~ ~

[x] Set the VFO to the middle of its tuning range, 5 turns from full CCW on potentiometer R54.

[x[ With the rig transmitting into a dummy load/watt meter, peak the power output by adjusting
trim capacitor TC7 in the VFO Driver stage.

[x] Adjust trim capacitors TC1 and TC2 in the Cascode Amplifier Stage for maximum power output as
indicated on the watt meter.

[x] Adjust trim resistor R87 in the Transmit Driver Stage to set the power level you want.

[x] Alternate between the two previous steps until you are satisfied with the settings.

[x] Adjust the RF output power with trim resistor R87 to the desired power level.
Four-watts is recommended.
