Introduction and General
Description:
The AA8V station can look complicated and perhaps intimidating, but when it is
viewed as a collection of receivers, transmitters, transceivers, and amplifiers
that can be selected and placed on the air one at a time, it is much less
complicated. The station is designed so that the various receivers,
transmitters, amplifiers, and transceivers can be selected simply by throwing a
switch, without the need to plug or unplug cables. The equipment shown in the
photo is summarized in the table below::
Receivers | Transmitters | Amplifiers | Transceivers |
TenTec Jupiter Transceiver | TenTec Jupiter Transceiver | AA8V 6146B Linear Amplifier | TenTec Jupiter Transceiver |
Drake R-4A Receiver | Drake T-4X Transmitter | Wingfoot 813 Linear Amplifier | Drake R-4A/T-4X System |
AA8V 6x2 Superheterodyne Receiver | Wingfoot VFO Transmitter | Ameritron AL-572 Linear Amplifier | |
Hallicrafters SX-96 Receiver | AA8V VFO and 6AG7 VFO Amplifier | ||
Johnson Viking Ranger Transmitter |
Though any receiver can be used with any transmitter and/or amplifier,
certain combinations go together better than others, and I tend to use those
combinations. My preferred combinations are listed in the table below. When an
amplifier is listed it can be bypassed by simply turning it off. Below are some
general comments:
1. My favorite combination is the TenTec Jupiter with the Wingfoot VFO/Wingfoot
813 Amplifier system. The Wingfoot 813 amplifier is normally only used with the
Wingfoot VFO exciter, and it is normally turned on. When band conditions are
above average, I will run the Wingfoot VFO barefoot at 27W output.
2. My second most favorite combination is the 6x2 receiver and the digital
VFO/6AG7/6146B system. This is a 100% homebrew station. Under very
good/excellent conditions I will operate barefoot QRP with only 3W output from
the 6AG7 amplifier.
3. The Drake Twins are normally used together. They are a real pleasure to use.
4. The Hallicrafters SX-96 is normally used with the Johnson Viking Ranger on
AM. I usually operate AM on the 40m band. I also use the SX-96 for broadcast
band DXing and short wave listening.
5. The 6x2 receiver is normally used only with the digital VFO/Johnson Viking
Ranger or the digital VFO/6AG7/6146B system. The digital VFO makes up for the
lack of precise frequency readout on the 6x2 receiver.
6. The TenTec Jupiter is usually used as a receiver, rather than a transceiver.
I normally use it as a transceiver only on 160m.
7. The Ameritron AL-572 amplifier is normally used only with the Tentec
Jupiter. I eventually hope to use it on AM with the Johnson Viking Ranger, but
that combination is somewhere in the future.
Receiver | Transmitter | Amplifier | Comment |
TenTec Jupiter Transceiver | TenTec Jupiter Transceiver | Ameritron AL-572 Linear Amplifier | Used on 160m |
TenTec Jupiter Transceiver | Digital VFO and Johnson Viking Ranger Transmitter | A classic transmitter with a modern receiver | |
TenTec Jupiter Transceiver | Digital VFO and 6AG7 VFO Amplifier | 6146B Amplifier | I normally use the 6146B amplifier. I use this on the 60m band. |
TenTec Jupiter Transceiver | Wingfoot VFO Exciter | Wingfoot 813 Amplifier | This is my favorite combination. I normally use the 813 amplifier. |
Drake R-4A Receiver | Drake T-4X Transmitter | A classic combination from 1965 | |
Hallicrafters SX-96 Receiver | Digital VFO and Johnson Viking Ranger Transmitter | A real taste of 1955 AM operation on the 40m band | |
6x2 Superheterodyne Receiver | Digital VFO and Johnson Viking Ranger Transmitter | A real taste of 50s/60s CW operating on 80m and 40m | |
6x2 Superheterodyne Receiver | Digital VFO and 6AG7 VFO Amplifier | 6146B Amplifier | My second favorite combination. A 100% homebrew station. |
