1. Re: [TenTec] circuits in modules Scout / 556 (score: 1): Author: "Stuart Rohre" <rohre@arlut.utexas.edu>; Date: Fri, 13 Jul 2007 17:03:18 -0500; The module circuits of the Scout/ 556 look pretty simple to tune up. I have had mine apart considering what it would take to extend the 10m range to the high end of ten. The box is not too complicate; /archives//html/TenTec/2007-07/msg00200.html (9,289 bytes)

In fact, they must be because of the connector that they plug into. One could probably get prototype blank boards with edge connectors; /archives//html/TenTec/2007-07/msg00207.html (10,149 bytes)

Johnson" <geraldj@storm.weather.net>; Date: Fri, 13 Jul 2007 20:49:10 -0600; Most tentec gear has a 5 MHz PTO and a 9 MHz IF, running RF at 5.3 MHz makes for lots of birdies in and out. Probably worse than the early 17 meter setups where the 9 MHz IF doubled to put out a sign; /archives//html/TenTec/2007-07/msg00208.html (9,793 bytes)

It was not hard to tape a 1:1 board layout and etch it.; /archives//html/TenTec/2007-07/msg00210.html (9,754 bytes)

Actually, the Scout has a 2.5 MHz PTO, but the second harmonic may cause trouble, although there is a low pass filter on the PTO output. 73, Bo; /archives//html/TenTec/2007-07/msg00219.html (10,792 bytes)

Johnson" <geraldj@storm.weather.net>; Date: Sun, 15 Jul 2007 11:17:23 -0600; Double balanced mixers produce more output power from the second harmonic of the drive than they do mixed output from fLO +/- fIN. Even with a pure sine wave LO drive. Other mixers are generally less; /archives//html/TenTec/2007-07/msg00221.html (10,534 bytes)

DONT USE THE VFO AT ALL. Just a crystal osc with the 6.144IF. Don't know which side you must use; that will set the sideband. Since the 60M band is channelized; /archives//html/TenTec/2007-07/msg00226.html (9,771 bytes)
