A Crossroads and a Decision!

Making some decisions is not as simple as flipping a coin and acquiescing to some basic paradigm. If it's heads, I will do this and if tails I do that.

The critical decision is to stop ever again from buying some run-down boat anchor in hopes of making a score on a resale and only concentrate my efforts on new construction. The 3rd dimension is my age, as the time horizon for new projects is growing much smaller. Sounds like I have made that decision in just trying to frame the scope of the issue.

This may be the one last project, so it best be good. Yesterday I fired up two rigs, the first being the Transcom SBT3 and the second my homebrew Hybrid Wireless with the JF3HZB dial. Side by side and switching only the antenna between the rigs, the Hybrid Wireless won by a huge margin. 


A Homebrew Tube SSB Transceiver from Isreal

[Several years ago, I spotted this rig from a ham in Isreal, and he was kind enough to respond to my email. His finished rig is a work of art. Note the Styrofoam thermal insulation around the VFO Box.  The IF Transformers are made from ARC-5 parts. I have three such transformer cans, where two are for the IF and one for the Balanced Modulator. These cans were a gift from N2CQR. The Filter is an 8 pole 9 MHz unit from KVG... Yep, have one of those too.]

Looking in the junk box, I have more than enough parts to build a 2nd Hybrid Wireless only this one on 20M. Needless to say, this one will also have the JF3HZB dial. Time to dust off those Greenlee chassis punches! 

This immediately raises the specter of why Hybrid versus all solid state. In part, the answer is that vacuum tube rigs is the place where I started and perhaps only fitting that tubes would be one of the final projects. I might even be able to fit in the 8042 finals I bought for the Transcom SBT3.

I located a local source for aluminum plate that has small cut-off pieces for sale and so that is another incentive for some metal bashing and chassis builds.

Bottom line: Stick to well-known topologies and concentrate on performance.

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
