[Drakelist] AC4R Rebuild Question
All, Just finished the AC-4 rebuild kit from the Heathkit Shop.

[Drakelist] Drake TR-4C T/R Relay - Update
All, Update on the TR-4c relay issue. I did the pull test - i.e. pulled the tube while the radio was hanging in transmit. The relay immediately opened and radio went back to receive. Seems that the relay is Ok. Pulled the 6CG7 and placed it in the Hickok 6000 tester. It tested as good but was low in the transconductance test - 2100 out of 2600 on one side and 2400 out of 2600 on the other. Is this tube considered bad for this application? If so, can I substitute a 6ev7 as the 6FQ7/6CG7s are getting expensive. Also, the copy of the TR4C manual that I have shows the 6EV7 as the vox amp/relay driver and has the associated voltage and resistance measurements for that tube. Does anyone have a similar chart for the 6FQ7/6CG7 tubes ? Thanks in advance 73 Gene K1NR - Web mail provided by NuNet, Inc.

I get a circular air flow pattern and the entire transceiver never even approaches warm. Just to make sure, (and for fun) I have a thermometer on top of the fan which sets on top of the one on the finals and the temperature hardly changes at all. To keep the fans stationary I use 4 pieces of coax seal rolled in a ball about half the size of a pea to serve as feet on each corner of the fan. It won't stick permanently but it will keep the quite stationary. So for me the question of blow out or in is answered by doing both As for providing power I have both the AC-4 and these series wired fans in a 3 way plug which is in turn plugged into a soft start circuit.

Re: [Drakelist] Station upgrade?
There have also been a number of articles in QST in the past year or so about the 43 foot vertical, and how to feed it, and how it will perform on various bands including 75/80 160.

I think a 43 foot vertical (with sufficient radials) would make a decent antenna on 160 meters and an excellent antenna on 80, 40 and 30 meters. On 20 meters the antenna is a bit more than 5/8 wavelength in length and a significant portion of the radiated RF will go nearly straight up and will not be reflected by the ionosphere due to the high angle. This gets worse as you go up in frequency. Could you work people on 20 and above? Sure, but it would be on a secondary lobe as the primary and strongest lobe of RF will be lost in space. Above 20 meters a 43 foot vertical is really a long wire pointed straight up. The other issue is that the required antenna coupler should be mounted at the base of the antenna to be fully effective. Yes, an apparent match condition could be achieved by using a coupler in the shack but that apparent match only serves to make the rig happy. Considerable RF is burned off as heat in the mismatched coax run to the antenna. It would also be interesting to measure the losses in the matching unun. If it's a ferrite or iron core those losses could be significant because UNUN's and BALUN's are not operating within their design spec if they are operating in an environment where the impedance is not purely resistive. RF transformers of this type are not meant to be used in reactive circuits. In my opinion, the antenna manufactures do a disservice to the community by promoting vertical antennas that are longer than 5/8 wavelength. Yes, you can get a decent SWR if you use 150 feet of lossy coax and an in-shack coupler. Yes, you can get a decent match with a 3/4 wavelength antenna. But, having a decent match and a decent antenna system can be two very different animals. OTOH, I applaud the use of non-resonant antenna designs. Being non-resonant makes for an easier job of impedance matching on harmonically related frequencies such as we enjoy in our HF spectrum. If you are primarily interested in 160 through 30 meters then I'd say the 43' vertical would be a good choice. If you're primarily interested in 20 and above then I'd go with a shorter vertical. In either case, I'd do my impedance matching at the base of the antenna. If you want all-band coverage and don't want to fool with an external coupler then I'd look at an all band vertical that has traps or stubs or variable length or *something* that makes the antenna a reasonable electrical height on the bands of interest.. Of course, this is all opinion and worth maybe a bit less than what you paid for it! ;-) 73, -Doug, W7KF http://www.w7kf.com I think its helpful to look at some older books on antennas that show the effect of length on radiation angle and the effect of the ground system on pattern. The ground is very significant, good antennas need good ground systems and, in general, its harder to get a good ground than a good antenna. Vertical antennas have a single lobe whose vertical angle becomes lower as the antenna length increases up to 1/2 wavelength. When it becomes longer than 1/2 wave the antenna begins to have a higher angle lobe, as mentioned above. While the main lobe continues to become lower in angle the performance will be affected by the high angle lobe. If the antenna is made longer eventually more lobes will appear. This is illustrated in a number of books. It _is_ possible to concentrate the radiation in a single low-angle lobe by using an array of stacked antennas but this becomes complicated, requires rather high structures for the lower ham bands, and, like most directional antennas, begins to be rather narrow band. The problem with antennas is that good performance requires space and the lower the frequency the greater the space needed. Some compact antennas work pretty well but they are always compromised in some way. I certainly agree that getting a good impedance match at the transmitter is no guarantee that any of that power is getting anywhere useful. -- Richard Knoppow Los Angeles WB6KBL dickb...@ix.netcom.com ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] New (to me) B Line...
Bill, You will love the B-line. The B-line is my daily operational rig. Check with Ron WB4HFN about methods to clean the dials. His web site has a lot of great information. Also once the you are sure that the Tx is running correctly, a good speech processor such as the new Ten Tec or the classic Vomax (available at Hamfests everywhere) can help in the DX pile-up situation. Just be sure you are using a good Hi-Z mic. 73 Gene K1NR On Wed, 9 Mar 2011 14:52:42 -0700 Bill V. wviga...@cox.net wrote: Hi All!

[Drakelist] Former chief engineer at the R. L. Drake Company SK
From the ARRL letter Milton A. Buddy Sullivan Jr, ex-K8YDO, of Washington, DC -- the former chief engineer at the R. L. Drake Company -- passed away from a stroke on October 28. He was 85. Sullivan designed and oversaw the designs of all the most significant Drake Amateur Radio products, including the 1A, 2B and 2NT transmitter, all the 4 lines and the beginning of the 7 line. After retiring from Drake in 1984, Sullivan ran his own business selling and setting up satellite television systems, an offshoot of his later projects at Drake that involved designing satellite equipment. After that, he went back to work full time as chief engineer for Lytton Electronics, where he worked until his final retirement in 1990. In 1993, he and his wife Judith moved to South Carolina where Sullivan worked for Alpha Delta, the small company owned by his former Drake colleague and long time friend, Don Tyrrell, W8AD. Sullivan donated his body to science. A US Navy veteran, he will be interred at Arlington National Cemetery after a term with the Georgetown University Medical School. -- Thanks to John Sullivan and Don Tyrrell, W8AD, for the information - Web mail provided by NuNet, Inc.

Re: [Drakelist] (no subject) cooling fan for Drakes
A 220VAC run on 120V will do the same trick. Moves air and is relatively quiet. Lots of 220V fans at the flea markets for cheap. Fans should generally be mounted in such a manner as to take advantage of any natural convection. A perfect location is above the cage for the finals pulling the air up from the final and exhausting up, and not blowing down. 73 Gene K1NR On Fri, 29 May 2009 12:32:55 -0400 Kris Merschrod k...@merschrod.net wrote: Yes, by all means draw the heat away.

Re: [drakelist] Speaker Question
Eugene Balinski [EMAIL PROTECTED] made an utterance to the drakelist gang -- All, Back in the day when new hams and/or SWL's were looking for a good sounding speaker, we would recommend a Radio Shack Minimus (sp?) 7 bookshelf stereo speaker. They were affordable as compared to the speakers from the various radio manufacturers (especially when RS ran a sale), and they generally sounded better. Unfortunately, that speaker is no longer sold. However I am sure that RS still sells a similar unit now, or you can try to find a pair at a Hamfest. 73 Gene K1NR -- Hello, On the PalStar website, the SP30 speaker is listed as being 6 x 6 x 6. On the eHam.net Reviews, the most recent review, dated Sunday, Sept. 2nd says: It appears that the physical specs have changed, as the one I received, (direct from PalStar, in three days), measured 4.75H x 6.5W x 6.75D. 4.75H would be an almost exact height match for the 4.6H TR-7/R-7. Has anybody heard anything about the PalStar SP30 dimensions changing? Has anyone else received a 4.75H PalStar SP30 speaker? 73, Bruce WA8TNC - Web mail provided by NuNet, Inc.

Re: [drakelist] WTB an AC-4 or AC-3
Eugene Balinski [EMAIL PROTECTED] made an utterence to the drakelist gang -- There are a number of speech processors that will work such as the Magnum-6 (Drake Version) and the Vomax. I have a Vomax and it works well. They normally run about $25.00 - $50.00 (sometimes less) at the flea markets. One thing - be sure that you place a fan blowing out over the finals.

Its really good compared to all the general usage crazy glues found everywhere. The general types don't like plastics too much while this one was developed specifically for plastic.Its Testors 'Super Glue', 1/5 Fluid Onces. It can be found Wal Mart in the plastic models shelves in their toy department. Its in a small red and white blister pack. Be careful there are other glues offered but they will not do as they are of the plastic solvent type and these are useless to us. Once open make sure that the bottle is well closed after usage and keep in an airtight jar in the fridge. This glue is great for all kinds of repairs to older rigs, glues metal parts too. Go very very easy when applying...it runs like water! If you get some on your finger tips just rub your tips together until the glue hardens( a few seconds) do not stop rubbing until its hardened!

I replaced mine with knobs from an old Knightkit tube tester. A bit different in shape, but not as likely to come apart. The Drake knobs fail because they are very thin in the direction of the most force on the lever switches. The Knight knobs are much heavier, hence a bit bigger. They work great.

[drakelist] Drake Plastic Part Deterioration
Eugene Balinski [EMAIL PROTECTED] made an utterence to the drakelist gang -- Listers: I just unpacked my MN-4C after a few years in storage. It was stored in a plastic bag (original ?) in the original cardboard box. I went to use it and I noticed that the plastic button used to set the SWR cal was cracked along the side. I don't remember it being cracked when I put it away. Later a similar plastic knob that controls the capacitance range also cracked. Has anyone on the list seen anything like this ?
