Very popular radio system, produced from 1978 till 1983. Excellent sensitivity, comfortable using, quality sound. Frequency range - АМ/SSB: 535-30150 kHz, FM: 88-108 MHz. Available BFO Pitch. Possible to connect external antenna. Also operates from eight D cells. The RF-4900 is similar to the earlier RF-4800, but with a green fluorescent digital display rather than a red LED digital display. AM and FM frequencies are digitally displayed. RF-4900 has been sold outside the United States as the model DR49.

So, the RF-4900, the same DR-49 is what it is. It's a nice sounding tabletop set that was designed to satisfy the listening needs of the average non-technical SWL'er. I think it does that very well. It is fun to use and has very pleasing, loud undistorted detected audio. Panasonic did something right in that area. Sure, it's not as stable as an Icom Pro in the SSB department...but touching up the BFO every once in a while was part of the radio experience thirty years ago. It does do a respectable job of SSB for casual listening. Sensitivity seems fine.

  Looks ok, working fine, save a lot of time in my case, finding a bad sensor in 15 minutes, but can not read counter information`s. Only can reset.

  John, I wanted to thank you for the excellent service you provided to me. My printer is now working again! There is a site based in England called \"fixyourownprinter.com\". If you want I can leave a message on their forum recommending your site. Let me know if you want this.

  XP322 ran out of copies and froze up. I read up that it was an Epson device to sell more printers but discovered your site just before treating it to a display of bad temper. The 20% of extra time will make the replacement question easier and i can use my stock of ink up on this 4 year old printer. I may even use your services to zero life the counter as it isn't a bad device really. Thank you so much.
