the 2800 and 2900 have more than the display as a difference. just look at
the schematics, it is quite obvious. I don't think many people ever check that point out since most people repeat it. I checked it out for myself and there ARE differences !!!!!

I think they were selling the Panasonic RF-2900 new around then too. The RF-2800 and 2900 were about ten years before the B65 and B60. The latter two were real PLL designs, not analog with a frequency display (counter) like the 2800/2900. The 2900 is identical to the 2800 except it has a fluorescent display instead of red LED's on the 2800, which saved battery power. The 2800 display only worked for AM/shortwave tuning, not FM. The current Tecsun/Grundig S-350 is loosely based on the RF-2800/2900 but it does not have dual conversion like the two Panasonics did. I've been trying to locate a National Panasonic DR-29. This version was not sold in the US. It had a built-in preselector to reduce images and overloading in strong signal areas like Europe. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |
Oh, I know the feeling. When you are ready to pull the trigger the
only listings are closed!! Good luck in the search..when you find one it will be worth it. |

I checked it out for myself and there ARE differences !!!!! The differences are mostly associated with the display circuitry. Did you find any significant differences in the RF/IF areas of the schematics? "starman" wrote in message ...
