RESTORING THE KENWOOD R-5000 RECEIVER - PART 5

Image
RESTORING THE KENWOOD R-5000 RECEIVER Part 5 You may remember I picked up this old Kenwood R-5000 at a local Hamfest over a year ago. Fairly early on, I noticed that the frequency readout was a little out - around 35 Hz to the low side. Not really a major issue, but certainly something that could be fixed with a little time and patience. And one of the great things about this vintage Kenwood rig is that it's relatively easy to get inside the case and service it. The following video demonstrates the process I used to make a small adjustment to the calibration of the rig. Missed Parts 1, 2, 3 and 4 of this series?

STATION NEWS AND THE LOG BOOK - April 28, 2017

The Diamond Power Supply that drives part of my radio shack. STATION NEWS AND THE LOG BOOK April 28, 2017 STATION NEWS AUSTRALIA The ABC has just posted an excellent little video on one of their AM radio transmitters, located at Cumnock in central west New South Wales. Being on a clear channel, this 50 kW mediumwave outlet on 549 kHz is well received throughout the night in much of Australia. No wonder! The location and transmitter setup is ideal - take a look! Here are two links to click for further information on this transmitter site: The video tour (3:35 min duration)  -  The ABC Central West radio transmitter An ABC article -  Rare public access into powerful Cumnock radio transmission site and how it broadcasts the ABC JAPAN After the A17 transmission season commenced, Radio Japan registered an additional 30-minute service to the Korean Peninsula. It is scheduled for 11990 kHz between 0815 and 0845 UTC via the Yamata transmitter site in ...

STATION NEWS AND THE LOG BOOK - April 21, 2017

STATION NEWS AND THE LOG BOOK APRIL 21, 2017 STATION NEWS AUSTRALIA As some readers will have already read in other DX forums, an AM/FM commercial broadcaster (relaying programming from mediumwave station 4KZ) in Far North Queensland (FNQ) has succeeded in an application for a SW licence, on 5055 kHz. The purpose is to relay this broadcaster's network, north to regions that have great difficulty delivering reliable AM/FM services due to great distances, rugged terrain that impedes signals and the cost and maintenance of relays /translators. Looking up the Australian Communications and Media Authority's (ACMA) website, I've found the licence registration. It was only approved on March 21, so this is a very recent development. The registration has been approved for: 1) A "tuned longwire" antenna, (the station has indicated an inverted V antenna) 2) Non-directional (ND) with 2.2 dB gain. 3) Licensed for 1kW with an Equivalent (or effective) I...

RETRO RECEIVER #6: KENWOOD QR 666

Image
RETRO RECEIVER REVIEW #6 Click each image to enlarge. KENWOOD QR 666 By Craig Seager VK2HBT This time, we cast our eyes over an early solid state receiver from Kenwood - the QR 666. Somehow I doubt whether the selection of the model number “QR 666” was some oblique reference by Kenwood’s technicians to the biblical number of the beast, borne out of some apocalyptic vision of receivers to come. Interestingly, 666 is also said to be the sum of all the numbers on a roulette wheel. Either way, there wasn’t a “665” preceding it. In fact, it seems that the only attempt to bridge the gap between the very successful Trio-Kenwood 9R 59 series of receivers and the next general coverage offering was an amateur band only set - the R-599 - a pretty neat and well performed unit with brushed aluminium fascia that paired with the T-599 transmitter. According to Fred Osterman's reference guide  Shortwave Receivers - Past and Present , the QR 666 was launched around 1974 and contin...

LOG BOOK - Good High Frequency Reception

Image
LOG BOOK Good High Frequency Reception This week has seen considerable activity on the surface of the Sun. As reported by Dr. Tamitha Skov, geomagnetic activity, minor storms and generally unsettled conditions have resulted in the 10.7cm solar flux numbers driving into the high 90s, with a corresponding uptick in the A and K indices. So,  considering we are now well into the low part of the sunspot cycle,  frequencies above 13mHz have been better than usual this week. There could be some further solar disturbances around April 17th and between April 23 and 29. What does this all mean for reception on the shortwave bands? Basically, in your daily monitoring of the bands, you shouldn't just write-off the higher frequencies! There will be times when the 13, 15, 17 and 21 mHz shortwave broadcast bands could provide good reception conditions. Of course, this also means that the 14, 17, 21 and 28 mHz amateur bands could offer some good DX conditions. Below is a li...

ECOS DEL TORBES, VENEZUELA FROM 1972

ECOS DEL TORBES FROM 1972 Transcribed and Translated by Alfredo Cañote Here is the second in our series of Rare Radio Recordings. A regular reader of MEDXR and Twitter friend, Alfredo Cañote, has kindly supplied the transcribed text for this recording, and included an English translation. ECOS DEL TORBES, San Cristobal, Venezuela. This station broadcast for many years on the frequency of 4980 kHz in the 60 meter band. I made this recording on October 8, 1972 as the station signed-on at 1004 UTC (8.04pm local time in Melbourne) . Unfortunately, the signal on this evening suffered from considerable atmospheric disturbances (thunderstorm/lightening static). Alfredo has done a wonderful job of deciphering the announcements through the noise! Below is the recording, transcription and translation for you to follow along while listening to Ecos del Torbes.
