"Howard Traxler" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Is this not how the Drake is supposed to behave on AM? Some kind of "carrier control" modulation; causes the carrier to come up when modulated. I don't think (at least with the tube models) that the finals could handle steady full-power carrier. 73, de, Howard, WA9RYF ----- Original Message ----- From: "Jim Shorney" <[EMAIL PROTECTED]> To: "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> Sent: Saturday, October 20, 2007 5:31 PM Subject: [drakelist] Which brings up another problem....
: : "Jim Shorney" <[EMAIL PROTECTED]> made an utterance to the drakelist gang : ---------------------------------------------------------------------- : : I was testing the WV4 with my TR7 at 29 MHz, and noticed that the carrier : power (AM mode) would shoot up to around 60 watts, then fall off rapidly to : around 12 watts. I don't have a CW key hooked up ATM, so I was using AM mode : with the mic gain turned all the way down. : : This suggests to me that one of those nasty three-legged silicon fuses is : heating up rapidly and possibly failing. Or maybe a PIN diode? Has anyone : seen this before as a problem, or is this just an artifact of abusing the AM : mode? : : 73 : : -Jim : : : -- : Ham Radio NU0C : TR7/RV7, TR6/RV6, T4XC/R4C, L4B, NCL2000, SB104A, R390A, GT550A/RV550A, HyGain 3750, IBM PS/2 - all vintage, all the time! : : HyGain 3750 User's Group - http://groups.yahoo.com/group/HyGain_3750/ : : : ---------------------------------------------------------------------- : Submissions: [EMAIL PROTECTED] : Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body : Hopelessly Lost: [EMAIL PROTECTED] - help in body of message : Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net : ---------------------------------------------------------------------- : : : -- : No virus found in this incoming message. : Checked by AVG Free Edition. : Version: 7.5.488 / Virus Database: 269.15.3/1081 - Release Date: 10/19/2007 5:41 PM : : ---------------------------------------------------------------------- Submissions: [EMAIL PROTECTED] Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost: [EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net ----------------------------------------------------------------------
