Re: [Drakelist] Drakelist Digest, Vol 67, Issue 1

Hello Demis, you may want to try reseating the DR7 first. I would say that EXACTLY 2 MHz offset indicate a digital problem. The relevant circuitry sits on the DR7. The connector is on the upper left when the front looks to you, 9 Pins. If you have an intermittent there, it could cause the prob

Re: [Drakelist] Connecting Signalink to TR-7?

Hello Gary, I am not particularly familiar with the Signalink but it seems to have the usual connections like AF-out, AF-in and PTT. The TR7 is not at all uncommon in this respect. Keying is low-voltage positive and the audio connections are not different from other transceivers. I used mine

Re: [Drakelist] R7 AGC issues

Thanks Paul for sharing this! I found the fast AGC on the R7 useless, too. I will try the proposed mod on my R7. @Jim, would you say that the service manual describes the right methode for aligning the AGC? I have had my doubts about it in the past, mostly because 'fast' would always create

Re: [Drakelist] Removing the Load Variable Capacitor on a L-7

Hello Roger and group, I had the same problem with an L-7 I bought some time ago. It came without P/S, was cheap and had 3-500ZG with graphite anodes from RF Parts. But I was aware of a short in the load cap because you could hear it when turning even without RF applied. I bought the whole thi

[Drakelist] Connector for L7-PS

Gentlemen, I am currently after an L7 missing the power supply. It will not be a big problem to build a decent p/s but will I be able to get that 8-pole connector? Especially here in Germany it is probably hard to get. Can you give me some sourcing hint? Thanks and 73 Dieter "Sam" DL5RDO T

[Drakelist] WTB MS-7

Hello Drake community, my R-7 is always jealous because the TR-7 sitting next to it has an MS-7 while the R-7 only has the internal speaker. So I am after another MS-7 to restore full fairness on the table again. Should anyone of you have one for sale, please let me know. Thanks Dieter DL5RDO

Re: [drakelist] tr7 oscillation, predrivers blown.. My drake b-line twins are laughing!!!

Hello Craig and group, I had problems with oscillation on my TR7. Setting the predriver to minimum gain did not help so I removed R2209 which is in parallel with the gain pot of the predriver. (I have board #2 with one MRF476). This further reduced gain and my problem was solved. I am still get
