Re: [Drakelist] FS-4 with a 4 line

Re: [Drakelist] FS-4 with a 4 line

Sherwood Engineering also makes an interface kit for the FS-4, see http://www.sherweng.com/ham.html#fs-4 What you are seeing is normal. The capacitance of the coax from the FS-4 will change the frequencies of the band xtals. Have to unplug FS-4 from R-4B to correct or can build this adapter, s

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 ampli

Re: [Drakelist] FS-4 Replacement?

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? The manual does indicate there is a difference between either pin on the crystal socket - just plug it in and ground the outer shield. Thanks Steve KD2ED

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 amplificati

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 bet

Re: [Drakelist] FS-4 Replacement?

Bob - Not particularly difficult. You need about 2-3 V p-p from it, maybe less, which means you may need a transistor, or possibly an MMIC. I'm not familiar with the IQPro, but for this duty you'll need to cover from about 11.6 to 40.6 MHz in 500 khz steps. It would be more convenient if you

Re: [Drakelist] FS-4

I have owned several FS-4s over the years but do not have any now. The FS-4 can be considered as stable as a crystal BUT it does not add anything to overall stability to the R4C, for example. Why? The main part that contributes to drift is the PTO so whether one uses and FS-4 or plug in crys

Neil - Needs to be low capacity cable, as short as possible, (12-18"). RG-62A/U, RG-59/U, Belden 8421 Mic cable, etc. 14 - 18 pF/ft. 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 sock

Re: [Drakelist] FS-4 Anomally

Hunter - Wrong crystal in the FS-4. You need the 9.6 MHz instead of the 9.59 MHz that's in there, which is the one is for the SPR-4. You might try a 'Want' on the various classified lists, someone may have an R-4(any) one and need the one you have! 73, Garey - K4OAH Glen Allen, VA Drake 2

Re: [Drakelist] FS-4 Anomally

Hunter, I had a similar problem many years ago. It turned out to be the wrong crystal in the FS-4. The fellow I purchased it from was using it to control a SPR-4 receiver and I was using it to try and control R-4C frequencies. Changing to the proper interface crystal solved the problem. GL,

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'

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 cente
