The only receiver I had was an old medium wave receiver with tubes that was modified to receive 80 meter SSB amateurs. And then just after my schooltime in 1976, this receiver was in the shop, price was reduced considerably as the S-meter was damaged. It was bought from the first money I earned as a soldier. It became my first all band receiver and gave me the chance to discover all the amateurbands. It has been used intensively in the shack, although it is certainly not the best receiver there is. It was used for the reception of:I always listened to this CW station when learning CW and later just for fun. Nice to hear that it transmitted my call. TX was the homemade 80m CW TRX. You will not see this receiver so very often. The newer FRG7 was better and more popular. The Racal RA17 was the best receiver with the Wadley principle but had tubes, it had to warm up, was very big and very heavy.The one knob preselector is replaced by a circuit with switches and a variable capacitor. There are some other minor changes like a RF attenuator and a mains supply. It can even be used with internal batteries and telescopic antenna, just as the Barlow Wadley. Nowadays, I do not use the SSR1 so often anymore as there are two newer home made receivers here, described somewhere else on this site.In principle, it is a receiver from 2 to 3 MHz. The whole band 0 MHz to 31 MHz is converted to this frequency range in 1 MHz steps. The Variable Frequency Oscillator (VFO) should be tuned close to 45.5, 46.5, 47.5,.73.5, 74.5, 75.5 MHz, depending on which 1 MHz range between 0 MHz and 31 MHz you want to receive. In passive mixer 1, this desired 1 MHz range is converted to the 1st IF of 45 MHz (44.5 - 45.5 MHz). http://www.blackbookmedia.co.za/uploads/carrier-infinity-touch-control-installation-manual.xml drake ssr-1 manual, drake ssr-1 service manual, drake ssr 1 manual, drake ssr 1 service manual. In passive mixer 2, a harmonic from the 1 MHz harmonic generator is also converted with this VFO signal to a 42.5 MHz amplifier. In the passive mixer 3, this 42.5 MHz signal converts the 1st IF downwards to 2 - 3 MHz, the 1 MHz tuning range of the basic receiver. If the VFO drifts a little in frequency, the 1st IF and the 42.5 MHz signal do also drift with the same value but the difference (the 2 - 3 MHz signal) will not change. So the stability of the 2 - 3 MHz output signal of passive mixer 3 is only dependent on the stability of the 1 MHz crystal oscillator! Air coils in the various bandpass filters. In January during a weekend on the countryside, I could test the SSR1 with a long wire antenna. That was totally different compared to my noisy indoor antenna in the city. It was freezing -6C. It was nice to be outdoors in the freezing cold on the countryside.We found the problem of the SSR1: the 1 MHz comb generator of the SSR1 was an unreliable circuit and had to be readjusted when it was cold. When the SSR1 was warmed up, it worked very well with the long wire antenna, although. In the evening, the SSR1 was overloaded by the strong signals from the long wire, especially on 40 meters. And the 20dB attenuator at the rear side of the SSR1 was or too much or not enough. Later, it was replaced by a variable attenuator at the front side of the SSR1. Also the BFO drifted off the frequency when the temperature changed and had to be retuned then. It would be better to use the fine tuning knob to vary the frequency of the BFO instead of the VFO.The sensitivity of the SSR1 is very good. A disadvantage was that the noise in pauses was just as strong as the CW and SSB signals. Therefore, listening was quite tiring. An IF gain control was added later, so that the sensitivity and background noise could be reduced manually.But the SSR1 could not receive any signals below 450 kHz. http://agro-avangard.ru/public/carrier-infinity-thermostat-manual-pdf.xml Later, the SSR1 was modified so that longwave reception was also possible and spotting the CW beacons became one of the hobbies.That is necessary for reception with the telescopic whip antenna but not with the long wire antenna. Intermodulation is -40 dBm, that is quite bad. With the long wire antenna, nothing could be received in the evenings at many frequencies like the 40 meter band. The 20 dB RF attenuator at the rear side of the receiver was not really a practical place. So a potentiometer has been added as RF attenuator on the front side. With 20 to 30 dB attenuation, sensitivity is still good enough and suddenly many stations can be heard on frequencies where you do hear all kinds of noisy intermodulation signals without RF attenuator. Happily the receiver has a preselector at the input and not a broadband filter as modern receivers have. The manufacturer did also discover that the receiver performs better when the RF gain is lower. The emitter resistor is 22 ohm in the diagram but was increased to 100 ohm in my receiver to lower the RF gain.That was also the reason that the SSR1 did not work when it was cold. It was a 1 MHz RC oscillator that was synchronized by a 10 MHz crystal oscillator. Very often I had to open the receiver and to adjust it because it did not synchronize anymore. I replaced it by a 1 MHz crystal oscillator.A potentiometer was added to reduce the MF gain and the AVC was modified. Reception is much more pleasant and less tiring with lower MF gain. Strong CW signals were unstable in tone height. It was solved by increasing two resistors from 2k2 to 18k. Later a new mixer with a fet was added to the BFO circuit.I replaced the voltage stabilizer by a 7812 but that was not the cause of the problem. The problem was FM modulation of the VFO by the magnetic field of the power transformer. I removed the power transformer and do use an external 12 volt power supply. http://superbia.lgbt/flotaganis/1649291636 It is possible to tune it to the correct position on the slope of the 455 kHz filter when it drifts a litte.This receiver was designed for portable use. The SSR1 is however always used as a base station receiver. A problem is that the 1st IF is 1 MHz wide, all kinds of strong signals are present and mixed in the 1st IF and the 1st and 2nd mixer. Therefore, dynamic range and intermodulation are not as good as that of a modern base station receiver with a narrow filter after the 1st mixer. Also the side band suppression is not so good and it does not have a CW filter and noise blanker etc. Stability is good enough for SSB but not as good as that of a receiver with DDS and PLL technology and not good enough for certain digital modes. The analog frequency scale is not as accurate as a digital display. For serious work, you will need a better receiver. But after the necessary modifications, it was always nice to play with this receiver, it is used very often!Not so good but good enough for many QSO. Tell us something about it!

The other version with mosfets in the local oscillators and a rather more sanitary harmonic generator using a 7490 decade counter between the crystal and astable oscs. Curious to know which type I had, I pulled the cover off as soon as it arrived; neither - yes to bipolar local oscs but a 'kludge' board on the back of the harmonic gen with the 7490 on it! NHHThank you for the education. The Standard 6500 also came from that manufacturer. 73 John KC0GThere is a hand written note to the effect that VR1 is not present on all sets indicating the change to a divider type circuit. The reason for the change becomes clear on reading this seems like temperature effects could easily shift the free-running speed of the astable sufficiently for it to lock on to the wrong increment of the 10 MHz crystal osc. Presumably the kludge board was an interim measure until the main board could be redesigned, but why didn't they just use a 1 MHz crystal osc. Interesting stuff I think, or perhaps I'm just easily pleased! NHHThe web page by PA2OHH is interesting reading. I did not know that the circuitry of the XCR-30 Mk II and SSR-1 had so much in common. Perhaps one should not be surprised. Trevor Wadley had made the design of the XCR-30 Mk II as simple as it needed to be to do the job. The early version of the XCR-30 Mk II used discrete transistors in the audio p.a. stage. The later version, like the SSR-1, used an i.c. amplifier. The SSR-1 had a poor reputation when it was on the market. The comments in various editions of the World Radio and TV Handbook were far from complimentary. PA2OHH makes the reasons clear, not least of which was that it was a portable design in a base station's clothing to be used as a base station. http://basumati.com/app/webroot/ckfinder/userfiles/files/Canon-powershot-d20-manual-espa-ol.pdf There was a further stage of development. Lowe with the SRX-30D, and Century with the 21D models offered a digital frequency display. The Century 21D manual be found online. The display used two long since obsolete MSM5525RS counter chips, one for the MHz digits and the other for the kHz digits. The arrangement was quite clever. The 21D also used SL1641 mixers. I assume, but do not know, that the SRX-30D was very similar to the 21D 73 JohnBTW, I see the XCR30 use a 1MHz crystal oscillator - I remain puzzled by the 10MHz and divider arrangement on the later variants. NHHIt could all come down to something as unsubtle as money or rationalising parts usage. David. The main tuning knob (large) rotates the outer dial (10 kHz graduations). If the AC line voltage fails an automatic circuit switches to the internal D cells. Later production features a trap door on the top panel for easy access to the battery compartment. This was the only Drake receiver made outside of Ohio. It mas made in Japan. Jack, RF Gain, 32 Memories, Dimmer, Two TuningSupplied with an 120 VAC adapter. The earlier O.E.M. model PRN1000 (produced for the People's Radio Network ). I remember doing dome good listening on this. Its your basic barlow Wadley type Rxer. Full coverage..5 - 30Mhz. in 1 mhz segments. Very like FRG7. Similar in size, similar to use, similar performance. I never had it back to back with Frg7. I have owned both but not at same time. But both gave good results. Its a coin toss between them, if given the choice it would come to price. I would buy another if it came up at good price, if just for the Drake name. Nothing fancy, but if you were just getting into radio or wanted to do a little fun listening occasionally, its a good buy Its one of those radios I think will be still soldiering on when the poles melt or equator freezes. Over the years I've used this as a non-Ham receiver. Great AM Shortwave broadcast receiver with strong audio from the wisely mounted front speaker. https://webhostmurah.com/wp-content/plugins/formcraft/file-upload/server/content/files/1629b3f727a304---cougar-owners-manual.pdf Paired with a Palomar broadcast loop I've enjoyed BCB DX. Like any other receiver, the more antenna you give it, the happier it is. Only problem is a non-functional S-meter. Wrote to Drake some 20 years ago and got a nice letter with suggestions. But, the meter is actually bad. Maybe I'll look for another now that I have the Internet to search. Along with my Kenwood TS-530S the SSR is one of those radios that never gets old. Tuning is a bit tricky but not difficult and in crowded bands one needs to be careful. The receiver is very sensitive with a good antenna and has reasonable sensitivity with the telescopic antenna. Audio is excellent and selectivity adequate but limited by the design. Frequency stability is very good as well as accuracy. I have been testing this using a digital receiver as a control and the SSR1 is right on the dot. USB and LSB work OK and even in AM mode the clarify control works. The major drawback is the lack of a good service manual so you need a compendium of what is available in the Web. There are two versions, one using only bipolar NPN transistors and another using MOSFETs for the local oscillator circuits. Mine has the MOSFETs so I don't know how it compares to the other version. Servicing is not difficult if you have some experience and the correct schematic. The best one for the MOSFET version is an schematic for the Standard C6500 available at mods.dk. This receiver has the exact same circuit as thexSSR 1. Only the cabinet and front panel design differs but the controls are the same. The schematic has pin voltages for all transistors in the radio. The dial say Drake all over it but I would have liked a blue dial better. It is an elegant radio designed to blend in a living room environment. In the end it is a good SW receiver and a nice collector set with a circuit design that marks the transition between the classic design of the superheterodyne and the advanced PLL and DSP designs of today. https://www.risingstars.com.tr/wp-content/plugins/formcraft/file-upload/server/content/files/1629b3f731b29a---Cougar-sv2-manual.pdf As previously stated, some learning is required for tuning. You must manually select the range then tune the MHz dial for highest noise level, then do the same for the preselector. I easily copy sideband and AM signals. Fairly limited with the rod antenna, but great with an external wire or dipole. Had alot coming back with synthesizer problems. If it were me and I wanted a solid state Drake I would opt for an SPR-4 if well checked out and no problems with the tuning mechanism or one of the later black face Drake receivers. I guess it would be OK if you don't get ahold of one of the problematic ones. I would rate it the least desireable of the Drake receivers for practical use. But now it is a collectable like all the Drakes so you might need it to fill a spot in a collection. Tuning this set takes a bit of learning (some peaking required), but it isnt a big deal. Readout is analog and reasonably accurate. The set looks really good to my eye and has proven to be very reliable in a harsh salty marine environment. Made in Japan and quality is great. It runs on AC or internal D cells and battery life is very good. It is harder to sue than a digital set, but actually more fun. It is not rare, but it isnt plentiful either. They seem to hold value very well so if you want to own one for a while you probably wont lose a dime if you later decide to sell it. Sensitive, reasonably stable, gets SSB OK. This set gets bad reviews from people who compare it to later technology, but for a 1970s set I think it is great. Apparently the only DRAKE receiver produced in Japan. Selling for approx. 350.00 in 1975, it really is a pretty good communication receiver. The sensitivity and stability are excellent. All in all this is a pretty good ham receiver. It is an excellent broadcast band receiver too. With the use of a QF1A audio filter,for extra filtering, it makes a comfortable ham receiver.

Did not find a service manual but did find a couple of good circuit diagrams. There was at least two version of the circuit and the radio I have is the latter version with 7400 and 7490 logic chips in the harmonic generator. Someone had already replaced the transistor and zener diode 5 Volt regulator with a 7805 so all i had to do was tidy this up and use more modern bypass capacitors on the device. Emailed a fellow in the USA who worked for Drake still although they were no longer into Ham Radio and he was looking after these heritage radios. He suggested the problem was in the 3SK39 Dual Gate FET and as I could not find then easily DownUnder he sent me some in the post. I replaced Q6 but the problem still existed.Did I say retire ? I retired four years ago and I do not know how I had time to ever go to work. This time the Drake had to wait until I was layed up recovering from a knee replacement.I found these the hard way, wasted quite a bit of time finding out why it had completely stopped while I was poking round inside.I found a German language manual on Mods.dk for the Standard SR C-6500 (the same radio with a different front panel) and this had a better block diagram, it had the transistor designations on each block of the block diagram. I had worked out the first local oscillator (45.5 to 75.5 MHz) was Q6, a 3SK39 dual gate FET, and it was not oscillating below 48.5MHz. What could cause that. My answer was little ceramic capacitors that had gone low in capacitance. The original Drake manual that came with the radio had a stamp on the front cover reading Seiwa Corporation, perhaps this was the manufacture of Standard radios. Something went wrong.
