Can this Siemens be used as a radio receiver or only as a meter?

@Radiocose Жыл бұрын

In general, a selective level meter can detect and demodulate electrical signals like a receiver can do, but what is lacking in a selective level meter are some special features of a typical modern receiver, for example configurable AGC, noise filtering/blanking, band scan, squelch and tone control, etc. not to mention the advanced signal processing, recording and diplay functions of SDR receivers.

@@Radiocose Thank you for your answer. Most of it is over my knowledge and I understand nothing. :) It is that such a meter is to sell from an ebayer I already bought some stuff and if I can use it as a primitive radio (well, I have enought commercial radio sets for the commercial shortwave, middlew. and long waves, but not for outside this bands) than I would add it to the package. No, I do not need fancy stuff like SDR, AGC, etc.

@@AdamGeorge-pb3fm yes you can use a selective level meter as a receiver, especially for low frequency bands.

I don't know what it is, but there is something...intensely interesting...to me, listening in to those signals being intercepted out of the "ether" in real time. Because whatever it is that is on the other end, perhaps half a world away, you are listening to it real time, be it an actual person, music, or a recording.

@Radiocose 4 жыл бұрын

Does the Tecsun have a movable antenna for MW? I don't think so. In any case, the quick test in the video was to enlight the superior AM performance of the old Panasonic, whatever be the reason (longer ferrite, different budget class, etc.). IMHO the Tecsun is a very good small portable on SW, but its MW performance is strongly limited by the background noise (worse than its predecessor PL-600).

Salve, ho un tappeto che usa questo motore e dopo qualche minuto che ci cammino sopra mi cala di velocità fino a fermarsi. Ho provato a farlo andare senza carico e dopo più di mezz'ora non aveva diminuito e non aveva scaldato eccessivamente. Una volta è calato così tanto da far saltare la corrente in casa. Vorrei avere la certezza che è il motore e non l'elettronica, in questo caso lo potrei comodamente sostituire. Grazie per il consiglio.

@Radiocose 5 жыл бұрын

Mi dispiace, non sono un riparatore di tapis roulant. In ogni caso, potrebbero essere anche altre parti del meccanismo che provocano un eccesso di carico per il motore, ad esempio il tappeto stesso quando sostiene il peso di una persona. Consiglierei di rivolgersi ad un riparatore.

Great video Radiocose, thanks! Was contemplating purchasing a PL-660, this video and some of the comments convinced me otherwise. I wanted a little smaller and lighter radio than my RF-2200. I did buy from Amazon the PL-880 a couple weeks back, it's Medium Wave AM reception was horrible, so I returned it. Was hoping the PL-660 was better. The RF-2200 is definitely the holy grail of MW sensitivity. I did like the PL-880's (and I would think the PL-660 would be similar) Shortwave and FM reception though, even with the telescopic antenna.

Ken Webb Hello Ken, please consider this is only a very quick and informal comparative test, even if it was made under pretty fair conditions, I think. More in general, yes there is some mysticism around some of those vintage radios IMHO (which reflects in sometimes unrealistic prices on a well known site of on-line auctions). But in the case of RF-2200 I think I can say it is a very good radio indeed, one that it is a real pleasure to operate and to listen to.
