Re: [Drakelist] FS-4 Replacement?
Yes there is a difference. The 'common' lead is the correct one. The other one will 'work', but you have to use a specific crystal switch position, with the other just any 'open' position works. The 'other' lead bypasses the amplifier and connects the FS-4 RF to the feedback link of the amplifier transformer. The key with either position is that the shield of the FS-4 cable must go to the chassis, NOT the 'other' crystal pin. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs www.k4oah.com scpmil...@aol.com wrote: I am curious too - if I am interfacing an FS-4 to an R4B (or even a C or an SPR-4) which pin on the crystal socket do I plug into?

Re: [Drakelist] FS-4 Replacement?
I'm curious Garey about why not the other lead? It just shouldn't be grounded? Maybe a 0.01 in series with the shield side? Or, couldn't he do a 6:1 balun and a 2 cond. shielded cable? (Admittedly, it's more work than simply one side of the socket and chassis ground.) His impedances would match better with the balun. I think I'd do that-and I also think I'd do a little cabinet with a switched set of ranges using your 500kHz suggestion AND switched BPFs. That'd be 'clean' and pretty nice.

Re: [Drakelist] FS-4 Replacement?
Ed - Because the crystal socket is in 'series' with the Emitter of the BAND oscillator transistor. The 'bus' that ties all the sockets together is the Emitter, the Base is bypassed to ground, and the Collector is the output. Unless he's short on drive voltage, he may not need any amplification, or a balun, at all. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs www.k4oah.com Ed Tanton wrote: I'm curious Garey about why not the other lead?

The center conductor needs to be plugged into ANY crystal socket, to the pin that is 'common' to all the others. Typically the bottom pin of each crystal socket, and the shield of the cable to chassis ground, NOT to the other crystal socket pin. It does not matter which crystal socket is used, nor does the socket used have to be selected from the front panel. The cable should also be unplugged from the receiver when using the internal crystals. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs www.k4oah.com Neil M Califano wrote: What cable can be used instead of the original Drake cable for the FS-4 - R4A?

Re: [Drakelist] FS-4 Synthesizer Dail lights intermittent
Doug - The bulbs are connected, in parallel, directly across one-half of the power transformer secondary. So the most likely problem is a bad ground on the bulb connections. You can verify by measuring the 'ground' side of one of the sockets. They should all read '0' ohms power off, and '0' volts with power on. Or you can just find the ground connection for the bulbs, and if it's a ground lug or other connection that is bolted to the chassis, just slightly loosen and retighten the bolt. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com douglasny...@aol.com wrote: Hello to the group.

If the cable is short enough, RG-58 is ok. RG-59 is better, and RG-62 is better still, but if it's only a foot or so ... 'Small' coax such are RG-174 etc., should not be used. The key factor is the capacitance / foot, the lower the better. The correct connection to the receiver is the center conductor to the 'common' crystal wire that connects all the crystal sockets together, and the shield connects to the chassis. A crystal base can be used to make the connection to the 'hot' lead, but the shield still needs to go to the chassis, which is NEITHER of the crystal socket pins. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com Hunter Ellington wrote: I have a very nice FS-4 I recently came across to use with my R4-C.

The FS-4 changes in .5 MC steps. It will totally dupe the FS-4 in this regard. nothing else makes sense. now as far as up-down buttons vs a VCO, I would like to put it to a vote. The original idea design was planned for a VCO but I thought personally that I would like buttons but lets see the consensus. Someone suggested blue LED's to match the line I will check on that. one more thing if this item would not be top quality I would not involve myself so that will not be a issue.

Re: [drakelist] FS-4
David Austin [EMAIL PROTECTED] made an utterence to the drakelist gang -- Hi Dan, I understood immediately from your first post what you were suggesting, as I had also considered manufacturing an almost identical product. I think there would be a big call for it from the Drake community, especially at that price. If you could provide a Drake style front panel so much the better (see Wood Box product). The recent item from Wood Box Radio was a great product, but overkill for me as one of the great joys of the Drake is using that fantastic Drake PTO dial for tuning, and the Wood Box unit effectively completely replaces the Drake PTO, thus missing the point of owning a Drake (for me at least!) (See: http://www.cqdx.it/woodbox/DDS4.html ) In line with others, I think some method of getting 100kHz offset for those tricky TX frequencies (harmonic prone) would be an idea, but basically keep it as simple as possible. Maybe a prolonged push and hold down could implement 100KHz increments, with, as you say, display showing the start frequency of the PTO dial on the main rig, with short pushes of the button re-setting to 500KHz increments? Also, what about a twin output deluxe version (two units in one box) for split frequency operation? Great idea. Go for it.

Re: [drakelist] FS-4 - my DFS-4
David Austin [EMAIL PROTECTED] made an utterence to the drakelist gang -- Hi Beppe, Re: the problem T4XC frequencies, would it be possible to have a third push button on front panel to activate 100KHz frequency steps for those few frequencies that need it to prevent spurious outputs from the TX? Maybe 100KHz steps only when holding down the 3rd button, then revert to 500KHz steps with next push of up/down button? Can it drive both TX and RX at same time, maybe with adjustable output level on each output (variable buffered outputs)? Otherwise, excellent looking design.

It would seem that this is indeed the case for the current Wood Box product, according to documentation, so presumably the new unit could be used in the same way (output parallelled to both TX and RX without loading problems of some kind). 73, David G4GTP - Original Message - From: Garey Barrell [EMAIL PROTECTED] To: David Austin [EMAIL PROTECTED] Cc: Drakelist drakelist@www.zerobeat.net Sent: Saturday, March 12, 2005 11:45 PM Subject: Re: [drakelist] FS-4 David - Well, I'm assuming your RX and TX have the original crystals. The WARC bands are covered by one FS-4, so unless you wanted to transmit on one WARC band and receive another WARC band - or - a non-amateur band you're covered with a single unit. I just couldn't think of an application for dual units off the top of my head!

Re: [drakelist] FS-4 --$$$$
Lee Bahr [EMAIL PROTECTED] made an utterence to the drakelist gang -- Not true about the cost of Beppe's unit vs Dan's unit. Beppe said they are working on a NEW DFS-4 that used a chip producing NO spurs, and the new unit would be less expensive then thier present DDS-4. (See below). Plus it has a neat cabinet. If you figure the cost of a box plus silk screening and you don't have to buy a power supply or any knobs or hardware plus the unit includes a display, I would say the unit easily could sell for more then $130 and have to sell for more then $130.. Also, Beppe's unit is built. So far there is no mention if the $130 unit is a kit where you have to build the unit or if it is a pre stuffed tested board ready to mount in a cabinet. Also how does it compare to Beppe's unit on spurs?. Beppe claims his unit has no spurs at all. That would be impressive. Beppe has given us some real facts regarding his unit. I find that relevant. Talking about what colored LEDs are going to be on a board and how many there are tells me very little about the unit. (It also tells me something about the producer). Maybe the $130 unit will be a good deal, but from what I have heard to date, you could not determine much from what was given the group. It doesn't sound like much engineering has been done on the unit if any to date from my prospective. So how do you come up with $130 before the design is firm? (The truth is, you can't). I would consider this project pie in the sky until I knew more about what actually if ever will be offered. I realize some of you guys take exception with me. So be it. I learned a long time ago, if something seems too good to be true, it probably is too good to be true. I am impressed with Beppe's unit because, they already have one product for sale, they are now developing another one at lower cost, and he has given us some real facts about his unit. Their design is not as yet firm and consequently they have not as yet determined the cost but their target is to lower it from the DDS-4 price. This is good engineering and marketing practice. Also, Beppe's unit will be complete. I feel a complete unit with no spurs is worth more then $130 and feel such a unit will cost the manufacturer more then $130 to produce. So, I'll be willing to pay more then $130 for his new DFS-4. (Let's see how much you have in a $130 unit after you add all the extra stuff to make it work and look good). Also, will this unit really be offered for $130 or will the price slide and float? Sure, I would like a Rolls Royce for $20,000 but I realize you can't have something like that for this price. If the $130 unit turns out to be a real product, great! But to finish it off it is surley going to cost more then $130. Time will tell which race horse will deliver. For now, based on what has been told to me, I'm betting on Beppe's unit to be a winner. The cost of Drake twins costing less then a Wood Box unit? Well are you talking about 1975 dollars or 2005 dollars? Are we talking about a DDS-4 or a DFS-4? (Maybe the apples and the oranges are getting mixed up here). My advice to myself is: don't buy based on price, buy based on value. Take it or leave it. I don't care. It will be interesting see what the future holds and what is developed by these two groups and see who's intuitive reasoning was correct about these two groups in the final analysis. Lee, w0vt I'm Beppe IK3VIG, member of WoodBoxRadio Team maker of DDS-4. Reading discussion about the new FS-4 generator, we are working on a simplified and less expensive DDS-4, called DFS-4.?

Lee, the FS4 (http://www.dproducts.be/Drake_Museum/fs-4.htm) was a crystal replacement box. You inserted it into a crystal socket. The output was in 500 kHz steps. Why would you want that in 500 or 100 Hz steps? It is not a VFO replacement, it is a band crystal replacement. help from knowledgeable people.. Right now, you say the unit has push button switching and doesn't use rotory switches. There are push-button switches with two buttons, and a dial readout, it looks like this: B N B Where B is a button, and N is a display showing the number. If you press the top button, the dial goes up one number, if you press the bottom button, it goes down one number. This could very well be used in a FS4 replica. The display only have to show the start frequency of each 500 kHz band. Myself, I would prefer rotary switches though... For another FS4 replica, see QST June 2004, Give That Drake Receiver a New Lease on Life, by Steven C. Hageman.

HI all, I have a FS 4 to use with my "C" line and need a cable to hook it up. Can anyone tell me where to buy one. A friend told me it is a special cable and not just a piece of mini 8 coax with rca jacks on each end. Any help appreciated. I am new to Drakes and this is my 1st set. They came from a one owner and was not talked on much. I have all cables except the one for the FS 4. Thanks for any help. Ruby Byrd KF4NI North Carolina

Re: [drakelist] FS-4 Problem
Marty - No service manual that I know of. Check supply voltages. DeoxiT the switches. Check the 74192 divide-by-N (U3) and associated control logic (U4 U8) on the A300 Digital board. Board closest to the back. I have seen more than a few of the 74192 chips fail. Don't know why. Check the 7490 divide-by-ten (U1) also on the A300 Digital board. This is supposed to divide the 5MHz clock by ten to provide the 0.5 MHz reference to the phase detector. Let us know what you find. 73, Garey - K4OAH Atlanta Allen (Marty) Martin wrote: The .5 frequency does not function correctly instead of switching .5 mhz it switches a full 1 mhz.

[drakelist] FS-4
I have just purchased a Drake C line with the FS-4. The FS-4 did not work but I noticed the comments about cleaning the contacts with Deoxit. I got hold of some and it is magical. I had cleaned the contacts with ordinary contact cleaner - looked great but still not working. Got my Deoxit today - not cheap - cost me over $40 Cdn for 25 ml needle dispenser bottle of 100% liquid. Put it on and rubbed with a cotton swab on a stick and now have a new FS-4. Works fine. Will give all the contacts in the R-4C tomorrow and see what magic it does on that. A couple of the fellows were asking about shipping. The non-aerosol product should present no restrictions. Great infothanks for the help! 73 Dick VE4QK --- Outgoing mail is certified Virus Free.

[drakelist] FS-4, Contact Cleaners, Bulbs Knobs for the 4-Line
Hello to all of the list, the following text is a little bit longer then usual and therefore it may be some lines to read, but as i had some requests to hold my FS-4 related comments public rather that private, i will do so. For the readers that are uninterested in the one or other topic, i apologize in advance for stressing your patience - in no way it's my intention to be annoying or intrusive. First, thanks to the various comments on the contact cleaner, it de- finitely will try to get DeOxit in England. My personal experiences with some products from the former "Kontakt Chemie" company are not the best in professional circuits. Especially equipment treated with "Kontakt 60" showed the trend to reappear with exactly the same pro- blems appr. half a year after the cleaning. "Tuner 600" worked a little better with this respect, but also not 100% satisfying. I cleary have to point out, that my personal experience with this two products is now laying years behind - and in the meantime the com- pany may have changed the receipe of this products significantly without changing the name. My best experience with contact cleaners in the past has been the product "Rivolta SLX1000" from a company named "Bremer Leguil", but due to more stringent environmental regulations in Europe, this product no longer is on the market, and the successor of this product by far does not match the per- formance of "SLX1000" for RF and other electronics stuff. So, if you should have the one or other can from "SLX1000", keep them like gold. To my knowledge, this also in the past was the pre- ferred product by a bunch of professional companies like RS, amongst others - and the usually select very careful, what they use. In Germany, there is another product available, which looks very promising and which will undergo a detailed test by me, if it finally will arrive here (i have ordered five cans). The name of this product is "EML200F" from "Electrolube". If of any interest, i will post the results of my tests here in this forum - please let me know. In Germany this contact cleaner (it is labeled to be a "con- tact cleaning oil") is sold by the company "Rainer-Frtig Elektronik". A 200[ml] can goes for EUR 7,95. The link to their homepage is (you have to scroll down to the bottom of this page): http://www.rainer-foertig.de/Bastler-Geraete.htm Please note, that i do not have any affiliations nor do i have any other commercial interest in / with the companies i mentioned above. I just wanted to make live easier for the readers of this lines by providing "where to get" information. The same statements goes also for the companies that i am naming below in the FS-4 section. So, now for some FS-4 comments: First of all, it may be a tricky job, to obtain some of the semicon- ductor parts for this synthesizer. So, i will do some comments on the individual parts: - MC1733 (U1): Obsolete part from former "Motorola Semiconductor", now "ON semiconductor". This is a 200[MHz] differential amplifier with some selectable, fixed gain settings. If of any interest, i can scan the datasheet and dis- tribute it as a PDF-file. This part may be obtained from "Rochester Electronics" (www.rocelec.com), where ONSemi / Motorola states that they would be their official source for obsolete parts. The location of this IC is on the "A100 VCO-Board" - MC4044 (U2): Obsolete part from former "Motorola Semiconductor", now "ON semiconductor". This is the phase detector for the PLL. If of any interest, i can scan the datasheet and dis- tribute it as a PDF-file. A 1:1 drop-in-replacement is the MC4344, which, however, is also obsolete. This part may be obtained from "Rochester Electronics" (www.rocelec.com), where ONSemi / Motorola states that they would be their official source for obsolete parts. A reason for this chip to die may be a minor design flaw of the FS-4: The pins 5 and 10 of this chip are tied together without any current limiting resistors which is in clear contrast to the Motorola application note "AN535" (although this apps-note is using a MC4344). Thus, these both ouputs may "fight" against each other, possibly resulting in substantial short circuit currents at this point. A suggested cure here will be: - open the connection between pin 5 and 10 of this IC. - leave R319 (8.2[K]) connected to pin 5. - connect an additional resistor with 8.2[K] to pin 10 and the other end of that resistor to the base of Q303 (2N3392). All this stuff is located on the "A300 Digital Board" Please note, that in that region at least two different versions of the FS-4 have been built: One, where Q303 is the only amplification transistor in the loop filter, and a second one (which i assume is the later on), where Q303 has been followed by Q304 (2N3404) in order to obtain a larger DC-gain in the loop filter. - SN7490 (U1): This chip is still available from a German broadline electronics distributor, which also has a sales office in the Unites

Re: [drakelist] FS-4
Hello Herbert, For cleaning the wafer switches of my Drake equipment I have always used the Kontakt 60 spray which is easily available in Europe. I doubt that DeOxit would do the job any better. For cleaning the potentiometers I use Tuner 600 spray. For cleaning the wafers it is a good practice to not directly spray Kontakt 60 on them but rather use a cotton tip (Q-Tip).

Re: [drakelist] FS-4
Good morning, Gene, you are absolutely right, this is the point to start with. In my previous answer, i just assumed without naming it ex- plicitely, that all the obvious checks and repairs for equipment of that maturity still have been performed - namely such things like contact cleaning, looking for and fixing any broken wires, faulty connectors etc., as this kind of stuff by experience generally makes up to 50% or more of typical equipment faults. Keyword DeOxit: As this appears to be a close-to-miracle con- tact cleaner according to all the reports, i'm looking to ob- tain some spray cans etc. of this particular brand. Does any- body know, where in Germany or in Europe i can get some of them (as far is i know, DeOxit will not ship to end users in Europe because of the danger for the air transport, that the explosivity of that material exhibits). Thanks a lot for all of your comments. Best regards Herbert, DG7MCC Gene McCalmont schrieb: Hello Dan; I have had problems with my FS-4 that were similar to the symptoms you describe and the repair was rather simple, which may (or may not) mirror your situation. The FS-4 uses wafer switches similar to those found in our other classic Drake rigs. Over the years, these wafer switches build up oxidation which interferes with the switch's operation. Before I would try any advanced diagnostic/repair techniques as offered by Herbert Schulz, I suggest you clean the wafer switches with DeXoit and see if this clears up your problem. Disassembling the FS-4 is rather easy and all of the components are readily accessible. Be sure to remove the top inner shield to gain access to the wafer switches under the shield. I use DeXoit D-100 in the small dispenser bottle rather than the spray can, so that I can concentrate the cleaner on the switch contacts rather than spray down the whole assembly. If this does not solve your problem, I personally would appreciate you and Herbert posting your discovery and repair techniques to the reflector rather than go private. We can all benefit from Herbert's considerable expertise in this matter.
