I have just completed some testing and wonder if anybody else has observed this problem when using an RV-75 with the R-7 or R-7A receiver; the use of the TR-7 or TR-7A transcieving with the receiver has no effect on test results.
The R-7 or R-7A never has the PTO completely shut off when using the RV-75 for frequency control. When the RV-75 controls the frequency, the R-7 or R-7As PTO always controls a frequency that is present, although only at an S1 to S2 level. For example, let's say you turn on the crystal calibrator on the R-7 and listen at 7300 and set the PTO to hear the tone of the calibrator. Then switch on the RV-75, whatever frequency the RV-75 is tuned to will be heard, but ALWAYS in the background will be the tone from the calibrator, at about an S1-2. If you turn the calibrator off, what ever is on that frequency will then be heard at an S1-2 level, in addition to whatever is being heard on the frequency controlled by the RV-75. I know what you're thinking now so let me provide added information. I've done the test and have mixed and matched the following...three different RV-75s, two R-7s, and one R-7A. Since they all have the same problem, I conclude that it isn't just one receiver nor just one RV-75. What is the probability that all three receivers and/or all three RV-75s all have the same problem? My conclusion is that that either all three R-7s have the problem and/or all three RV-75s have the problem. So my question is, has somebody else had this problem and corrected it? If so, would you be so kind as to share your insights into the problem? Right now, I don't know if all three receivers are the cause of the problem or if all three RV-75s are the cause. But I'd like to fix all of them. Thanks and 73s, Evan ---------------------------------------------------------------------- Submissions: [EMAIL PROTECTED] Subscribe: [EMAIL PROTECTED] - subscribe drakelist in body Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost: [EMAIL PROTECTED] - help in body of message Brought to you courtesy of TLCHost.net http://www.tlchost.net/ ----------------------------------------------------------------------
