RESTORING THE KENWOOD R-5000 RECEIVER - PART 1


RESTORING THE KENWOOD R-5000 RECEIVER

PART 1

A few weeks ago, I found an old Kenwood R-5000 receiver. In the first of a short series of YouTube videos to be posted during the coming months, we lift the lid on this fabulous piece of gear from the 1980s/90s. We'll begin to clean up, restore and modify this legendary radio to (hopefully) its former glory!

Here's Part 1 - Viewing at full screen HD is recommended.

73 and good DX to you all.

    I've seen several writings and video re the R-5000 and the hot power supply. From what I've been able to determine, the 12VDC power draw is a couple of amps. I'm wondering if it feasible to simply remove the old hot tranformer-based supply and substitute much cooler modern switching supply...like those providing 12vdc to many laptops. thoughts????

      Hi Allen, Yes the 12vDC draw is around 2 amps. I guess you could put in a smaller supply to replace the old iron transformer type. However, care would need to be made about the type of switch-mode supply selected, as many of these are very noisy RF generators in themselves. Indeed, some of the laptop supplies are the worst offenders for emitting RF hash. For me, I'd rather connect the DC leads to an external stable linear supply, which is what I have done here in the shack. Thanks for the comments. Regards, Rob.

RETRO RECEIVER REVIEW # 21 - The Kenwood R-5000

RETRO RECEIVER REVIEW #21 (You can click on all photos in this article for a close-up view) KENWOOD R-5000 Performance and Innovation by ROB WAGNER VK3BVW This extended blog post first appeared as a feature article in the February 2024 issue of The Spectrum Monitor magazine. Further details on this excellent publication are available at www.thespectrummonitor.com I have always wanted to own a Kenwood R-5000 receiver. Perhaps I was dazzled by the mystique that appeared to surround this rig. Somehow, it had always been on top of my bucket list of pre-loved rigs that I wanted sitting on the desk of the radio shack.  Finally, one showed up at a local Sunday morning Hamfest, and I happened to have just enough dollars in my pocket to make a purchase. It appeared to have lived a hard life. The case looked knocked around and was pretty dirty inside and out. So, while I would have liked to have owned a unit in better condition, the price was right, and I decided to take it on as a l...

PRODUCT REVIEW: WELLBROOK ALA1530S+ LOOP ANTENNA by Michael Stevenson (Guest Contributor) This is a review and my opinion of the Wellbrook ALA1530S+ P–1 Active receiving Antenna. For further information, details and specifications then please visit: www.wellbrook.uk.com Background I have been a keen shortwave listener since 1970 and have had many receivers and antenna types during this time.

RETRO RECEIVER REVIEW #20 - The SONY ICF-5900W

RETRO RECEIVER REVIEW #20 SONY ICF-5900W by CRAIG SEAGER VK2HBT This time around, I thought we might direct our attention to one of the many portable receivers of yesteryear, and it is perhaps appropriate that we choose a manufacturer that continued to produce quality equipment featuring shortwave coverage until long after. I’m sure our Japanese friends will concur with the submission that Japan is a land of short-lived, but enthusiastically embraced fads.  Whether it be karaoke, yo-yos with brains, electronics pets or Pokémon, each craze sweeps the country in such a way that captures the attention of the rest of the world and is usually associated with some pretty smart home-grown technology.   In the mid to late 1970s, shortwave listening (or “BCL”) was the flavour of the month, with teenagers (and some older folk!) compiling large QSL collections and forming SWL and DX clubs all over the country.  Nowadays, you’d be fairly hard-pressed to find any external broadcas...
