Only transmitters that give a signal of at least 15 dB¼ on the antenna H1 or V1 in the measurement test are shown. Omitted are transmitters that have a signal of less than 15 dB¼ or are suppressed by a stronger local radio on the same frequency. The remaining 22 stations listed in table 3 should be strong enough to be received by either a stationary radio with a horizontal and vertical dipole or by a portable radio with a telescopic antenna. <br><br> <table bgcolor="#bbffbb" border="2" bordercolor="#70ee70" cols=1 align="center"><tr><td> <pre width="58"> Table 3 MHz P.(H) P.(V) Lum. dB¼(H)dB¼(V)km Station -------------------------------------------------------- 87,6 (OK) (OK) (OK) 18 19 29 Radio Krishna.. 89,2 OK OK OK 38 40 11 Radio City 90,1 OK 12 25 29 Radio Joy.. 90,2 OK (OK) OK 33 21 20 Radio Ballerup 92,9 11 15 28 Radio Storkbh.. 93,1 15 14 43 Radio Kattegat 94,5 (OK) OK 28 17 19 Albertslund Nærra. 95,5 (OK) 16 17 30 Universitetsradio. 97,7 20 16 27 Radio Frederiksb.. 97,8 OK OK OK 62 58 2 Roskilde Dampra.. 98,2 (OK) (OK) 24 25 20 R.

The list of stations is not identical for the two receivers. Philips can receive two stations which are not received by Lumatron, and visa versa. Together, they can receive 17 stations. <br><br> So five  potential stations are not received. The signals from the stations at 92.9, 93.1 and 106.3 MHz are very weak and they are disturbed by splatter. Actually, they can be received by the Sony receiver with narrow ceramic filters in a few antenna/receiver positions. The stations at 97.7 and 104.5 MHz are a little stronger, but other transmitters create interference. <br><br> The outcome of the tests is that 15 out of 30 local radio stations in the Copenhagen region can be received in Roskilde 30 km west of Copenhagen with a Philips system or a Lumatron receiver. That is 9 FM stations more than can be received with an older  average portable radio. <br><br> It may be concluded that listeners living outside a larger city could receive several more local radio stations in switching from an old/cheap FM receiver to a modern receiver using indoor antennas. <br> </td><td border="2" bordercolor="#c0c0ff" width="80" valign="middle" bgcolor="#d0d0ff"><font face="arial" size="3"><br><br><br><img style="width: 80px; height: 1100px" src="http://www.morefmradio.dk/Tower.JPG" alt="telecommunication tower"></font><br><br></td></tr></table></td></tr></table><br></td></tr></table> <script language="javascript1.2" src="http://www.parameter.dk/counter/48c8b1faf410504fbe6301bc149ad788"></script> </body> </html>
