Re: New Design 3 Inch Baby FSL Antenna Demo Video

Phillip Fimiani
 

I bought two cheaper varieties... Should come in soon. They look alike, but the cheaper one is made from a duller looking aluminum... not stainless or whatever is used on the $40 ones. The materials will make the difference of course, Will it be a major difference in the overall pickup... Don't know... If it improves reception... Ill be happy...

I'm starting with a traditional X framed box antenna... maybe remote controlled possibly amplified... I want to place it a distance away in the attic.

Hi Paul,

Most NZ FM stations use RDS, so you'll be set for them next FM DX season.

I did a bandscan while on the Gold Coast earlier in the year, and looking at my notes, less than 50% of strong signals had RDS data.

I'm not sure what chipset the AR-1780 uses, but the following are my commented posted elsewhere on the AR-1733:

####
When I had a bunch of portables sitting on the car roof during an SpE opening the other day, I had an AR-1733 (si4736 chip) with me and it was easily outperformed by the Tecsun PL380 (si4734) and the KMart DAB12711.

Which got me thinking - WHY it wasn't as good as the PL380 (as they use a very similar radio chip)?

I pulled the AR-1733 apart and the reason it stinks on FM is that they've added Air Band reception as a completely separate radio system causing the RF path from telescopic whip to the FM input of the SiliconLabs chip to be convoluted. The si4736 is designed to be directly connected to an aerial - says so in the design brief. Adding air band has downgraded the FM Broadcast specs. Interestingly there is also a "weather band" chip there as well that isn't used - probably enabled by software in a USA "C Crane Skywave" version.

I wonder if the AR1780 has a similar design? If so, the FM performance may not be as good as you would expect.

Clock time is often wrong or missing.  Station automation software may

Re: FM RDS

I have several portables with FM RDS, and the factory radio in my 2003 Chevrolet Impala (which I believe was made by Sangean; it programs and behaves just like a Sangean portable) also has it. About half the FM stations in my area use it to display a running playlist of song title and artist name, the others offer little more than station callsign, frequency, and maybe a slogan (e.g. "more hit music!").
