December QST
The Tuna Tin “S” — A Bare-Bones Synthesized QRPp Transmitter
Bob Fontana, AK3Y
|
This update to a classic design includes tunable frequencies and a digital display.
In the May 1976 issue of QST, Doug DeMaw, W1CER/W1FB (SK), developed a two-transistor QRPp — “p” denotes less than 1 W — transmitter using a pair of 2N2222A transistors. Dubbed the “Tuna Tin 2,” the transmitter was crystal controlled and produced a 250 to 350 mW output for a cost of less than $10. In the March 2000 issue of QST, Ed Hare, W1RFI, provided an updated version of Doug’s original design. |
|
|
| Here, we take another step forward. The Tuna Tin “S” (for synthesized) keeps costs below $20 and is still small enough to fit within the confines of a tuna tin, but has an integral VFO, digital display, and a higher power MOSFET final. |

November/December On the Air
The Best Antenna for the Job |
| There is no such thing as a single antenna that’s perfect for every station. Choosing an antenna depends on what you want to do with your station, how much money you can spend, and any restrictions you may encounter with your property. This On the Air article will walk you through what antenna types are best for certain types of operating. |

November/December QEX
Remote Operating with a Raspberry Pi, Fldigi/Flrig, WSJT-X, and NoMachine
Harry Bloomberg, W3YJ
|
| My primary residence is on a small suburban lot where putting up a good HF antenna is a challenge. A few years ago, I inherited five acres of woods and an old Amish farmhouse 85 miles away. I hung some antennas from tall walnut and pine trees on the property and spent weekends and holidays operating from there. |

| ARRL is your Advocate |
| One of the most valued ARRL services that membership contributes to is ARRL’s advocacy efforts. Many areas of policy affect the Amateur Radio Service, from spectrum defense to antenna zoning. ARRL works to defeat unnecessary regulations by educating policymakers and mobilizing members to speak out on a range of issues. ARRL supports legislation on Capitol Hill that preserves and protects access to existing amateur radio frequencies as a natural resource for the enjoyment of all hams. |
