Ten Tec Jupiter/Pegasus External Transmit Receive Control Expansion |
 |
| On the back of the cabinet of the Jupiter is a phono jack labeled EXT T/R connector . This output is used to control one external amplifier. I enjoy using my Jupiter on HF and VHF with the N4PY software. I have several amplifiers and transverters that I need to control from the single T/R connector. This circuit expands the single output to six outputs. |

| I purchased the following parts at the local Radio Shack Store:
(1) Aluminum enclosure 2 ¾ x 2 1/8 x 1 5/8 (8) Phono Jacks (1) .1 x .1 piece of perf board 1 ¾ x 2 ¼ “ |
Here's what the inside looks like:
 |
| The perfboard is supported by a couple of long spacers and attached
by two long 4-40 screws. I use one of the 13.5v outputs on the back of the transceiver to provide power to this circuit. The same warning applies to this circuit as the one in the TenTec manual:
The new outputs are rated like the original: a maximum of + 24 volts with the current rating of 200 milliamperes. |
