A Look Back: Memories of the Panasonic RF-2200 and its Sibling, the National Panasonic DR22<\/h1>\n

One of the preeminent AM\/FM\/SW portables of all time is the venerable Panasonic model RF-2200 receiver that was sold in the USA starting in the mid-1970\u2019s for around $165.00 US.<\/p>\n

Weighing in at a hefty 7 pounds, 13 ounces and vital statistics of 12\u201d x 7\u201d x 4\u201d it came equipped with a robust shoulder strap to schlep from the radio shack to alfresco listening sites and was basically a completely self-contained entertainment center for the radio enthusiast.\u00a0 My first RF-2200 was purchased in the late \u201870\u2019s from Grand Central Radio Shop in New York City, now just a memory and long gone, but back then they sold a bevy of shortwave and ham radio equipment.<\/p>\n

It was love at first sight when I saw the RF-2200 in the store\u2019s gleaming glass display case way back when. The \u20182200 possessed all the bells and whistles to guarantee a good time for the SWL such as a rotatable ferrite AM broadcast band antenna, BFO (Beat Frequency Oscillator) for SSB reception, AM \/FM\/SW (3.9 \u2013 28 MHz) bands, a D\u2019Arsonval \u201cS\u201d meter that doubled as a battery status indicator, large four inch front mounted speaker, switchable coarse\/fine tuning speed, base\/treble\/RF gain pots, 125\/500 kHz crystal markers to calibrate the VFO, wide\/narrow bandwidth switch, dial\/S meter lights, earphone\/recorder jacks and telescopic antenna for SW and FM. Plus it sported the renowned Panasonic trademark.<\/p>\n

Part of the 2200\u2019s ample avoirdupois can be attributed to the unit\u2019s four \u201cD\u201d battery power plant, but Panasonic also supplied an AC cord to plug into the house mains and an earphone (located inside the battery case).\u00a0 It runs forever on those four stout dry cells, one of the many positive features of this vintage gem.<\/p>\n

Back in those days portable radios generally were not judged and valued based their diminutive size and weight but on the array of features geared to the end-user. Front panels were festooned with an array of controls rivaling an aircraft\u2019s cockpit.\u00a0 Knobs, analog dials, meters, large front-mounted speakers, switches and lots of black plastic were the order of the day. These all contributed to the beauty and practicality of portable shortwave radios back then.<\/p>\n

One thing missing though was built-in memory channels; those existed in the operator\u2019s brain and not yet delegated to memory chips.<\/p>\n

One of the features long gone and missing in modern receivers these days is the \u201crecorder out\u201d jack that looks identical to an eight-inch earphone jack and yes the \u20182200 has one. It was used to plug in a tape recorder to memorialize an op\u2019s favorite radio show. Of course back then there were many more shortwave stations broadcasting.\u00a0 Gone also are those tiny incandescent bulbs, sometimes described as \u201cgrain of wheat\u201d lamps that were used on S meters, dials, etc. The RF-2200 sports ample illumination for the S-meter and tuning dial which makes it a perfect bedside table radio for late night DX\u2019ers and insomniacs.<\/p>\n

Speaking of DX, the \u20182200\u2019s rotatable AM ferrite antenna is one of the main virtues this radio possesses.\u00a0 As an avid AM DX\u2019er and faithful disciple of AM radio in general, the \u20182200\u2019s rotary directional antenna nulls out noise and routinely pulls in stations as far away as Nashville (WSM), Chicago (WBBM), St. Louis (KMOX), Atlanta (WSB), Boston (WBZ) and Toronto (CJBC) when the sun goes down. Look closely at the antenna mount\u2019s base and you\u2019ll even see compass-like degree markings that\u2019ll help when retrieving a favorite local or DX AM station.<\/p>\n

Shortwave coverage is approximately from 3.9 \u2013 28 MHz as per the service manual, but I\u2019ve checked the actual coverage of my unit using a calibrated service monitor and found it to be 3.47 \u2013 28.9 MHz which makes sense since I\u2019ve tuned to W1AW\u2019s code practice on 3.581 MHz with no problem and have also heard the Volmet station on 3.485 MHz. That\u2019s good news for hams wanting to receive 80m CW.\u00a0 It gets a bit tricky though using the fine tuning option for CW hi hi.<\/p>\n

AM broadcast band coverage is only from 525 \u2013 1610 kHz as per the specifications; the AM band had not yet been extended to 1710 kHz at that time.\u00a0 The ITU approved the extension in 1988. With that in mind I wanted to determine what the actual band coverage of my unit was. Again, using an IFR service monitor it was found to be from 514 \u2013 1720 kHz; that\u2019s good news for those who listen to stations at the top of the band.\u00a0 It also explains why I can hear YWA, a non-directional radiobeacon (NDB) from Toronto, Canada just below the AM band on a frequency of 516 kHz. If you own a RF-2200 or DR22 tune to the bottom of the AM band and listen for it. You may also hear the warbling sound of NAVTEX stations on 518 kHz.\u00a0 Switch on the BFO and wait for dark, you might get lucky like I have.<\/p>\n

My apologies for not being an FM broadcast band listener so all I can state is the few times I\u2019ve listened it sounded absolutely great.\u00a0 The specs state a FM broadcast band frequency range of approximately 87.5 \u2013 108 MHz. Mine measured from 86.8 \u2013 108.9 MHz but I\u2019ve yet to realign my unit so these ranges may vary among the population.\u00a0 Note that I have undertaken the labor intensive task of aligning my National Panasonic DR-22 which is almost the exact same unit as the \u20182200. You can search this blog for my results that were kindly published by Thomas previously (click here to read)<\/a>.<\/p>\n

For those not aware, the RF-2200 was also marketed in Europe as the National Panasonic DR22 and in other parts of the world as the Cougar 2200. My DR22 was an eBay purchase, and that\u2019s the best place to find either model.<\/p>\n

DR22s are rather rare compared to the \u20182200 though. First off, one of the major differences with the DR22 is that it runs on either 110 or 220V, and that\u2019s accomplished by a switch on the back of the unit.<\/p>\n

\"\"<\/a>

DR22 runs on 120 or 240V via switch on rear panel<\/p><\/div>\n

The DR22\u2019s front panel stenciling is slightly different too, as shortwave bands are labeled \u201cKW 1 \u2013 KW 6\u201d in addition to \u201cSW1 – SW6\u201d.\u00a0 Not sure what \u201cKW\u201d means though. Perhaps some reader can enlighten us.<\/p>\n

Well, that\u2019s about it, if you want a RF-2200, or DR22 then window shop on eBay.\u00a0 Lately they have been selling from $40.00 US (parts only) to $455.00 for pristine units. That\u2019s a pretty wide price range and even I\u2019m surprised at the high prices being gotten for clean units.\u00a0 All I can say is that the two I have now are staying right here in the shack with me.<\/p>\n

Thanks for reading and 73\u2019s.<\/p>\n
