RE: [drakelist] AC-4 120-240V switch
Hi, Take a look on http://www.dproducts.be/drake%5FMuseum/ac-4_ps.htm 73s, JM CHERRY De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de [EMAIL PROTECTED] Envoyé: jeudi 25 mai 2006 22:18 À: [EMAIL PROTECTED] Cc: drakelist@www.zerobeat.net Objet: Re: [drakelist] AC-4 120-240V switch Hi John, I thought ALL the later model AC-4's were duel voltage units only requiring an internal wiring change. Mine is SN 55719. The latest serial number I have is 58298 and it is a single voltage supply. There are no cououts that don't have a factory connector mounted in them. It doesn't make sense to me that Drake would put a dual primary transformer in the power supply and hot have a way to switch it from the factory. Are you sure that the cutout is for that swith? Is it screened on the supply? It might be possible that someone removed the infamous 2 pin relay connector which would leave a cutout the same size as the switch. Check your schematic against the primary of the trasformer. If there are 2 sets of primary leads, then you have a dual voltage tranny, if there is only one set, it is a 120V power supply. 73, John
[drakelist] R7 audio
Drakelist de PA2DW, I am using a R7 in combination with my TR7 for some time now, with utmost satisfaction. What I do notice though, is the difference in the way the R7 sounds in comparison with the TR7 receiver. Especially with the AGC in position fast, the audio sounds very much like it is saturated in some way and there is a kind of crackling noise coming along with the received signal. I always thought it was my R7 that did that and it was something on the list to fix. But today I visited Evert PA2KW and his R7 did sound very much the same like mine! We went over it and tried tweaking the AGC but with no success Now I wonder if others experience the same and if there is a fix for it. It surely must have something to do with the AGC circuit. Evert and I decided to go and search for the service manual of the R7 which we dont have, so any source for that will also be highly appreciated! VY 73, Dick PA2DW has notified the sender that this message has been received.
[drakelist] blue lenses
Richard J. Fiero II W5TFW [EMAIL PROTECTED] made an utterance to the drakelist gang -- Hello all, I seek information, I bought new blue lenses for my Drakes, the dial lense was no problem however the s meter lense looks like to change it one has to remove the whole front plate. is there an easy way ? also I have a c-4 however the red and black push buttons dont allow the thing to stay on, once you take your finger off they go off I am assuming they are bad ( the switches ) am I overlooking something?
