January 10, 2025 Power Back on and We Are Ok.

I can best describe the past three days as Chu Lai circa 1965: No lights at night, C Rations and warm Beer. We are safe as the QTH is 40M NW of downtown LA so there was no fire activity close up and personal. But the power company shut off the juice as a precaution. The 1st thing I did is make a cup of coffee and cooked some eggs in the microwave.


Let me not kid you the devastation in Los Angeles is on a scale of the bombed-out cities in Germany during WWII. Statements from one individual as to the cause are simply not validated and shows a lack of understanding. But hey you have to throw red meat to the followers on a regular basis so why not use a catastrophic event to whip up the crowd. Sad and this reflects the poor choice.

In an informal discussion with a couple of neighbors who after the last blackout went and bought some stuff. One neighbor spent $1100 for a system comprised of a battery, solar panel and an inverter. Another neighbor bought a 1500-watt gasoline generator. Both were less thrilled with the results.

The neighbor with the 1500-watt generator discovered that he suddenly had choices. He could feed the refrigerator and TV (Choice 1) or make a pot of coffee (Choice 2). But he could not make Choice 1 & 2 simultaneously.

The neighbor with the inverter soon found out that the solar panel would not fully charge the battery during daylight and so the inverter was only good for maybe two hours full up. The fix: He hauls the battery to his wife's place of work at about 4PM and charges the battery so he can get enough capacity to run the refrigerator and maybe the computer and TV.

I am looking to build a system and am thinking a 4KW pure sine wave inverter with four 100 amp LiPO batteries and for charging the batteries a dual system: House power to trickle charge the batteries and a 1KW gas or propane generator when the power is out for battery charging. 




That outage has set my homebrew construction back a notch. You can think a lot on the dark but can't do any soldering.

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...
