The transceiver is designed for continuous wave (CW) operation on 7 MHz which is more commonly known as the 40 meter amateur radio band. The VFO in the NorCal 40A is a Clapp oscillator, which is a member of the Colpitts family since capacitors form the voltage divider network: We will analyze the NorCal 40A VFO in two stages. Looking at this truly wonderful manual indicates that this is a design from the early nineties - 20 years old. Since then, I ordered a NorCal 40A form Bob Dyer at Wilderness Radio before he retired. First is startup using small-signal (i. View and Download Norcold N400 owner&39;s manual online. I ordered my Nor Cal 40A with the KC1 optional Frequency Keyer. I swear, the receiver in this QRP Transceiver is just as capable of pulling weak signals out of the muck as is my regular rig.
The Norcal 40A 9(US) is a very nice rig and is also a type 2 kit. The receiver is a superhet with crystal filter, AGC, and RIT. It has the optional KC1 keyer/ freq annunciator built in. I know there is some interest in this radio and I&39;d rather avoid eBay, so: This is a Wilderness Radio I built from a kit when they first came out 25 years ago. Next project: NorCal 40A QRP xcvr I&39;m ready to start my next QRP kit, the NorCal 40A 40m transceiver from Wilderness Radio. 3 Chapter 17 - Receivers, Transmitters, Transceivers and Projects: The NorCal Sierra: An 80-15 M CW Transceiver - Page 1 Th ARRL H db k CD V i 3 0 C i ht (C) 1998 b Th A i R di R l L I. Our constant goal is to supply our customers with a fast turnaround of quality workmanship. Check also the NorCal 40A Assembly Manual for a complete schematic (last two pages of the manual).
The NorCal 40A transceiver was designed by Wayne Burdick. N301/ N304/ N401/ N404/ N501/ N504 Series. My board is revision C, from 1999. The revision B NorCal 40A is a third-generation 40-meter QRP transceiver kit, designed by Wayne Burdick, N6KR. The classic Norcal 40A 1 watt portable QRP CW rig--this one has the KC1 keyer/frequency annunciator installed. Here is a list of the individual components.

Norcal 40A - 40 meters CW QRP QSO with LA8IG - IW2NOY - Duration: 4:15. While the manual lists the differences between the A and B revisions, it doesn’t tell me what’s different between the B and C revisions. It is named after the Northern California QRP club.
The rig covers any 40KHz portion of the CW band, with a very stable VFO operating in the 2MHz range. 04MHz, the 40m amateur band. The schematic of this transistor switch is shown below (click on the schematic to enlarge it). Original manual, power cord. It is particularly well-suited to portable, battery-powered operation, having very low receive-mode current drain. The SST is a type 2 kit and is very comparable with the SW40+ except that it lacks the cleaner enclosure and its tuning bandwidth is less at 10-20KHz. The NorCal 40A was designed by Wayne Burdick, N6KR, for the Northern California QRP Club.
Received the kit a few days ago and did the parts inventory. A few of the parts are hard to find and may have to be substituted, notably the power transistors, and you&39;ll probably have norcal to use separate resistors in place of the DIP network. Just curious what mods exist for it that are popular for Nocal 40A owners. With the introduction of more brands into the market, the prices of air conditioners have reduced making them affordable to many people. The club is a group of radio amateurs that develop new transceiver designs. Since 1962 Nor-Cal Products has manufactured the highest quality vacuum chambers, components and engineered subsystems used in semiconductor, flat panel display, industrial coating, LED lighting, energy and research equipment. In the next lecture, we will look at steady state using a large norcal 40a manual signal analysis.
Wayne Burdick, N6KR, designed the NorCal 40 as a club project for the Northern California QRP Club. The best part is how well, the receiver works.

I&39;ve got an Icom 735, which is a good radio even by today&39;s standards. The KC1 works very well and it is nice to be able to push a button and tell where the rig is tuned to on the band. I’m not going to worry though, since the component placement drawing in. The parts needed for the Harmonic LPF are shown in the following picture. That kit still awaits the soldering iron. Call today for more information.
The frequency coverage can be increased up to 150kHz with one capacitor. This frequency is within the HF (= high frequency) band, which extends from 3 to 30 MHz. Often if there was anything of technical note, you would find mention of it in one of the ham rags i. Condition is Used. NorCal 40A as a vehicle for teaching RF circuit analysis and design.
138" long 64 material The original assembly instructions tell you to "after installing the ferrite bead on the base push Q6 down onto the PC board so that its leads are as short as possible". The NorCal 40A is a QRP (= low power) and CW (= continuous wave) rig. We at NorCal norcal 40a manual Manufacturing are devoted to giving our customers the highest quality products at a reasonable price. Norcal 40A QRP CW transceiver with antenna tuner. A complete kit for the NorCal 40A is available from the Wilderness Radio Company. I also added the KC1 keyer/frequency counter. Nor-Cal manufactures NW Half Nipple Vacuum fittings, fabricated from 304 stainless steel.
With /λ=cf, then f≈7 MHz. The assembly manual for the KC1 is also very straight forward and easy to follow. I&39;ve also asked to join the qrp-tech reflector, and will be updating my BoM and info as I learn more.
there is no NorCal 40 they are 40 meter versions of the NorCal 20 but they were not NorCal kits NorCal 40 will dead end you at the NorCal site there is the Wilderness Radio NorCal 40A for more info contact wilderness Radio PO Box 3422, Joplin, MO, 64803 there is also the Red Hot Radio 40 meter version of the Red Hot Radio NorCal 20. 5W 17m Transceiver Project. We understand the concept of supply & demand, and the requirement to be first or nothing. Excellent condition (one tiny mark on top if case, keyer instructions taoed to bottom), fantastic qrp radio, designed by founder of Elecraft N6KR. The price is right though at (US).
Plan is to make an aluminum enclosure as I did for the 5W20 with QRPGuys. QRP is a radio signal indicating a low-power station. The test with the 40A will be done during the day (or should test with someone far away). The DC40A, 30A, and 20A Transceiver. RIT and KC1 keyer; operating freq sent in cw.
The term NorCal is an abbreviation for Northern California amateur radi o club which initially participated in the prototype development. The part labels are from K7QO&39;s instructions, not the manual. It operates in the “40-m band,” which designates the wavelength of the carrier.

1 Introduction The NorCal 40A is a CW-transceiver operating in the frequency range from 7. transceiver, the NorCal 40A. The DC40A, 30A and 20A series of transceivers are designed by Steve Weber, KD1JV, who is a member of the QRP Hall of Fame.
But once the parts are in hand there is nothing especially. Not long ago, when air conditioning systems were dubbed as luxury vouchsafed which was designed for the few that are privileged. If you have any comments or questions, feel free to drop me a line at org Decem. The Norcal 40A is a 40-meter CW transceiver designed by Wayne Burdick, N6KR and sold by Wilderness Radio. The transceiver was designed and built by Wayne Burdick, N6KR, and field tested by members of NorCal, the Northern California QRP Club. The Wilderness Radio NorCal 40A is a REAL rig, not a gimmick or a toy. Wilderness Radio offers the SST, Norcal 40A, and the Sierra.
The goal of this problem is to put in the Receiver Switch (Q1) that protects the receiver circuitry when the transmitter is on. a This is similar to parts B and C of Problem 13 in the book, but adapted to LTspice. I did a suggested mod and changed the 40 kHz band coverage to 150 kHz and added a 10-turn potentiometer. General Description The NorCal 40 is a compact 40-meter CW transceiver optimized for ease of assembly and use. NOTE - the K7QO NorCal40A is actually from the qrp-tech group, and has some modifications from the original, so it&39;s not 1:1 with the manual, but it&39;s pretty close. The manual tells you exactly how to wire up and install the KC1 into the Nor Cal 40 A. Building the Norcal 40a from boards (and then finding the parts) is an intermediate to advanced project.
com digital display. Wayne originally designed the NorCal 40 transceiver as a club project,. Installation and Owner’s Manual N301/ N401/ N501; Installation Manual N304/ N404/ N504; Owner’s Manual N304/ N404/ N504. K7QO 17m Operating Station Photograph of the rig I&39;ve been using on 17m.
But, in addition to the 40A kit and the KPC1 keyer and frequency enunciator unit, I ordered an additional labeled blue face plate for the original 40A as shown above.
