Working the Winter Field Day.

Just to be fair to the 99% of the hams who only operate or do contests, I spent some time on 20M yesterday operating the Winter Field Day Contest. This is not sponsored by the ARRL.

Starting 1st with my rig, I used a homebrewed Dual Filter 9 MHz IF rig with the 20X4 Juliano Blue LCD. The rig choice was a struggle since the other option was my totally homebrew 20M SDR transceiver as that would be like shooting fish in a barrel. Using a filter rig in my view was an opportunity to show off!


For our new YL Extra Class Licensee's, this homebrew rig uses the "Drake Approach" where the BFO is set at 9 MHz and to achieve upper and lower sideband there are two Crystal Filters. The center frequency of one filter is designed so it will only pass the lower sideband. The other filter has the center frequency so that it will only pass upper sideband. Relay steering selects the proper Crystal Filter for the mode chosen (USB or LSB).

At one time a surplus distributor in downtown Israel was selling boards with the two 9 MHz filters plus an AM filter for $35. You also got a PCB with lots of salvageable hard to find components. As my good friend Abbie used to say, such a deal Vinney, such a deal. He called me Vinney and not Pete, as he said I looked like Vinney in the movie My Cousin Vinney. 

The rig is a single conversion design with the 9 MHz IF, Digital LO/BFO and we have the J310 Dual Gate MOSFET in a couple of places. The rig has two VFO's with memory so at a flick of a switch the radio boots up to the 20M FT-8 frequency. This is a good way to check band activity.

This rig was the 1st time I used a 20X4 LCD. The Driver is the 2N2219A and an IRF510 in the final. The chassis uses a wooden front and back panel.


To keep the footprint small there are several boards used versus one large single board. In the main area, two boards are stacked on top of one another. The bottom board has the two filters and other support circuitry, with top board having a steerable amp, the BPF and 2N2219A Driver. The IRF510 is mounted on the back apron.

Back to the contest... what a piece of crap! The exchange from me was as follows. After being recognized I supplied the word 1HCA. The 1 is a single transmitter, H for Home and CA for California. There was no signal report, nor power level. Not very exciting, but I bet the YL newly christened Extra soon will be releasing a you tube video to her thousands of followers expressing delight with being an Extra Class Ham and able to hand out 1HTX contacts.

This is what our hobby has become today, a cacophony of dumbed down dribble, reduced to a 4-digit alphanumeric code that requires no evaluation. Gone are the endearing terms... you are 37 Hertz low or your signal lacks presence or worse you have RF feedback on your signal. 

Where is the long-standing information sharing such as your QTH, the kind of equipment, your power and antenna. But of course, 1HTX avoids that you have only been a ham and Extra class licensee for 3 weeks, 4 days, 10 hours and 15 seconds!

The rig itself produces 5 watts on 20M, and I made one contest contact to TX using just the rig barefoot. For the other contacts I was running 100 watts using a CCI AN762 RF Amp. No one reported me for being off frequency and contact was made usually with one call. 

The rig is no IC7300 but something that most of the instant Extras can't claim is that it is a true homebrew rig (not a kit) being used in a contest.

Them that know, now don't care if you know.

Do not suffer the agita di stomaco for it is time that will change things in the government. The Mid-terms are step #1 and time is on our side.

January 26, 2024. A simple CW Transceiver/Transmitter

Cruise through the lower part of the ham bands bands and what do you hear? Well, FT-8 and CW. Often you will not hear any SSB stations yet go to the lower part of the bands, and it is a cacophony (I love that word) of bad sounding signals and some high-speed keying. Fast is not so much of the issue as is bad, run together and jerky keying. But none the less our hobby started there.    So, you could crank down your ICOM 7300 and watch the waterfall on CW or you could homebrew a radio. Actually, to do CW right you need more thought up front than you do with a SSB transceiver. Often, I will state that a CW Transceiver is much more difficult to build than a simple SSB rig. I published two articles in QRP Quarterly on CW transceivers and all I got was a yawn so maybe history will repeat itself.  Yawn!   30M CW Transceiver with RIT!   Of interest is that the LO is a Varactor tuned LC oscillator using a NE602. Look closely at the RIT circuit which is only activated on ...

August 30, 2024. A PNP 20M SSB Transceiver

Shown below is the Block Diagram for the 20M PNP SSB Transceiver steered in the  Transmit Mode . The components shown in the dotted block are relay steered so that the block module is single pass and amplifies in a single direction. The Block diagram show steered in Transmit.  Essentially the steering process works so that the IF Module input follows the Balanced Modulator on Transmit and then the input side follows the Receive Mixer on Receive. All done with some relays and a bit of RG174U coax. For those who count things in detail, this block diagram is not unlike what was used for the PSSST Transceiver which can be found on my website . Yes, a warmed over P3ST only using PNP devices. TYGNYBNT. 73's Pete N6QW

March 31, 2024. Happy Easter to those who celebrate this day.

What a great day to Binge on Chocolate and experience the pain of that filling that has been leaking.  I would be in that category with the leaking filling(s) had I not just spent an amount equivalent to one of the fancy new uptown appliance box transceivers on two filling repairs. Well at least I can binge on the Chocolate bunnies without fear of pain. Regrettably everything appears to have jumped in price including the price of parts. Well not so much the parts as the shipping costs.  That notably is seen in the eBay treasures. I spotted a nice heathkit DX-20 for about $50 and the shipping was $65. Likely it is a twofer with part being a way to in effect charge a higher price by inflating the shipping and in part by increased shipping costs. Shipping with insurance across the US was about $150 for this jewel and that was three years ago. 6AM on the Left Coast ~ 20M Easter Sunday! My only hope is the cost of Chocolate Bunnies remains steady although a pound of See's Candies f...
