July 25, 2024. Some "Clean Up Items"

Once again, the Amazon Phantom has struck! In yesterday's mail was a package from Amazon containing a pumice scraping stone to clean the toilet bowl.  To my benefactor I thank you, and I truly appreciate your generosity. Anyone else feeling the urge to send a pumice stone -- I am good. A gallon of 12% Hydrogen Peroxide ... OOOPS Here I am soliciting and that is not my intent. Please do not send any H202.


Now a giant plug for the G-QRP Club and the SPRAT publication. I am lucky to own a SPRAT on a STICK, which essentially is a compendium of all of the SPRAT articles going back to #1 and carried forward to the most recent all on a USB Stick. Be aware that the compendium is only as recent to when the stick was burned. 

But I did find Issue #61 on my stick which covers the Stockton Bridge in an article entitled A Bi-Directional Inline Wattmeter pp 12-16. (David Stockton, G4ZNQ). No "Digital Stuff" here just two meters. G4ZNQ's description of the circuit and its function is superb and easy to read. He actually developed this project based on some work he did in his professional career. A page from his article is shown below.



The calculation of SWR is based on the forward and reflected power and involves some math flogging.  The no calculation involved approach is to match the load to the rig to a point where there is max forward power and a minimum reflected power -- just watch the two meters!

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 ...

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...

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
