RE: [drakelist] TR-7 Receiver Noise
Carel, PA0CMU [EMAIL PROTECTED] made an utterence to the drakelist gang -- Hello Vic, It might be the powerline wiring from the on/off switch on the front panel to the connector on the rear panel. The 60 Hz /110V signal introduces a hum in the audio circuits. We modified the PS-7 by mounting a switch on the frontpanel and disabled the original on/off switching. Due to that, the PA fan must be replaced too. We used a cheap 12V computer fan. Now you can use your TR7 with forced cooling in the field too! 73, Carel - PA0CMU. From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [drakelist] TR-7 Receiver Noise Date: Tue, 07 Dec 2004 16:04:27 + [EMAIL PROTECTED] made an utterence to the drakelist gang -- Greetings. I recently put a TR-7 on the air that I purchased several months ago. All is fine except that there is what I can best describe as a low frequency rumble noise that is most noticable when using headphones. It is very audible even with the RF gain set to max and the audio gain set to min. I have listed with another receiver and do not hear this noise, so I don't think I have any interference in the shack. When tuning in signals, there does not appear to be any distortion, but the background noise is very noticable. Any suggestions greatly appreciated.

[drakelist] Mic Cable
James Chaggaris [EMAIL PROTECTED] made an utterence to the drakelist gang -- Hello all.. I'm rewiring some of my microphones for my B, C, and TR7 lines and was wondering what's a good quality cable to use that won't break the bank. I've also noticed that alot of distributors will only sell in bulk (100+ feet or more).

[drakelist] Tubes for sale
gwt [EMAIL PROTECTED] made an utterence to the drakelist gang -- Hello list members, I have a number of transmitting tubes that I wish to sell. Below is a list of the tubes. If you are interested, please contact me at this address. I have noted an asking price, but I will consider offers. I wanted to give the list members a first shot, before I list them on E Bay. Either way, I need to sell these tubes, as they are in excess to my needs. Tube list: Four BRAND NEW 4-400's. These tubes were manufactured in China. They have never been installed for use. I bought them as back ups for my AM transmitter. I have since sold the transmitter, so I don't need them. $75 dollars each, or all 4 tubes for $250 bucks. ___ Two used Eimac 4-400's. These tubes were installed in my AM transmitter for a short period of time. They have very limited hours on them. Probably not more than 8 or 10 hours. They have FULL output! $185 dollars for the pair. ___ Two BRAND NEW Eimac 3-500z's. These tubes were purchased new, as back up's for my L4B amplifier. $400 dollars for the pair. I offer a money back guarantee if these tubes are not as I have stated. George Taylor KE4HJ -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

RE: [drakelist] TR-7 Receiver Noise
Carel, PA0CMU [EMAIL PROTECTED] made an utterence to the drakelist gang -- Vic, Try this: - disconnect the AC-line! - remove the PS7 control cable on the rear panel of the TR7 - make a temporary connection with a piece of wire between pins 1 and 2 of the PS7 control cable connector. The PS7 is switched to ON mode now. - carefully connect the AC power - the TR7 is switched ON too, but without the AC current through the wires in the rig. - don't use transmit mode because the fan doesn't work either! - listen to the noise you heard before. If it's gone now, the AC wiring in the TR7 is the reason of your unwished signal. Good luck, be carefull, AC power lines are dangerous. Here in the Netherlands we even have 230V.

[drakelist] LF Noise
