[Drakelist] Wanted: TA-4 for SPR-4
Hello- Does anyone have a model TA-4 transceive adapter for the SPR-4 receiver that is for sale? I would like to mate an SPR-4 with a T-4XC transmitter. Thanks, Byron WA5THJ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] T4XB Power output
Hi Bill, Drake changed the tuning procedure from the manuals a while ago because of FCC regulations. If you are tuning for max you are possible in violation of FCC regulations. Your power out seems a little high to me. Here is a link to that information. http://www.wb4hfn.com/DRAKE/DrakeArticles/TransmittingTuningAlt.htm Al n7ioh On Aug 11, 2009, at 4:27 PM, Bill Maddock wrote: Guys, A couple of questions to the experts. I have a 4B line which I really enjoy - they work excellent although I haven't tried them on SSB because I have a TR4C for that!

I get slightly over 200 watts out of the TR4C. Of course the TR4C has 3 finals instead of 2! Next question is this - I generally tune up for max power out using plate, then load control and double check When I have my gain all the way up of course I get more out up until saturation point. This usually requires a higher setting on the load control. By the way I use the wattmeter in my MN2000 to measure this! After I tune for max I usually back down gain control so that I am running about 100 watts out or sometimes less - I never run it wide open. Should I leave the load control at the max setting or lower it some to get more out with less gain?? Am I hurting anything by leaving the gain set higher? Thanks for all the answers! Bill N4ZI ps If some one has a TR4CW without the RIT in nice shape for a reasonable price I might be interested! I already have RV4C so don't need RIT!! ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Re: [Drakelist] experience with TR-7 CW filter
I use the 500 Hz filter and it is more than adequate; Inrad makes excellent products. 73 de W4DL Mike ex AK7P * WA9SWF * WN9SWF - Original Message - From: "john" To: "Dennis Monticelli" ; Sent: Monday, August 10, 2009 6:40 PM Subject: Re: [Drakelist] experience with TR-7 CW filter I've got the 400hz InRad (I think that's it) and it's quite narrow. I can't imagine needing more narrow than that. I note no excessive loss with the 400hz Inrad or the 500hz Drake...

Does it ring excessively or have excessive insertion loss? Also, would you recommend an new InRad filter rather than a used Drake original filter?
