about broadcast engineering. He told me they are going to be doing some work on their main mediumwave antenna soon which they hope will improve the signal. In a follow up email, we were discussing ground conductivity here in Afghanistan and the merits of a 120/50 radial system. He also asked if I knew anyone who was using a CFA MF antenna system. I have written back to determine if they are looking to go to that system, or are using it now, but no answer as of yet. His email is (Al Muick-AFG, dxld Aug 5) Hasn't the CFA [crossed field antenna] been pretty well debunked by now? Or useful in certain applications (gh to Al, ibid.) The CFA hasn't exactly been debunked, but it has fallen into disfavor. Jean-Paul sent me this email, excerpted below: "My MF antenna is located at the sea front in mud water, excellent conductivity but Ant impedance changes with the tides. It goes from no water above the radial (low tide) to almost 1.7m at times. 50R to something like 60+j24 at worst. "Was thinking of a raised counterpoise GND system to sort out this problem but now we have to relocate as too much interference to phones and other equipment. New site is located in a small valley next to a water reservoir. "Was looking at CFA some time back. Had a rf specialist in Australia who was going to build one to do some test but then dropped the idea. Could not at that time find parts to build it. A colleague who went to Egypt says Radio Cairo has one on top of their Radio house. "I think will stick to series fed tower 90 degrees, although I read that folded mono pole(shunt feed) works better than series fed over poor gnd system and can be set to 50R and no ATU required." His current antenna was all over the j-omega scale because of the tides. That tells me they didn't put the antenna far enough out to where the tides would not affect it. All of the "sea antennas" I have ever seen are in places where the tide does not remove all the water. This is the reason they are killing all the phones and other things in the area. The raised counterpoise is good if they have the real estate to put it on or it is out of the way. There is always someone who will come along and hurt themselves on it. The Government of South Sudan was trying to get me to assist them to install one for their 100 kW transmitters in Goomba (when I was with the UN), but they did not want to spend the money to fence it off and the place was crawling with children. I respectfully declined. The folded monopole he is looking at would be good for him commercially, but would probably screw DX'ers because it greatly reduces the skywave content and converts it to groundwave, plus it has the added benefit of easy matching.

SLOVAKIA 7385 Miraya FM QSL, via IRRS via Rimavska Sobota, Slovakia. Card with full-data, except site, in 5 months for a report to Fondation Hirondelle, Avenue du Temple 19C, CH-1012 Lausanne, Switzerland. Upper left corner has orange & yellow Miraya FM logo, followed by info about Miraya FM, followed by "We are pleased to certify your reception of STAR radio Liberia."!!! The card was folded in half and lightly glued, but I was able to open it (there was nothing on the back). The last card I received from Hirondelle was also folded but permanently glued. Each arrived in an envelope large enough to accommodate an unfolded card. I'm very happy to receive these cards so I'm not complaining; I'm just curious as to why they fold and glue their cards. (Wendel Craighead-KS-USA, Aug 12, Cumbre DX via dxld) SRI LANKA Radio Ceylon Calling India - 11905 kHz SLBC's new broadcast to India at 1530-1630 UT on 11905 heard here with good reception on 2nd and 3rd August. It was only audible for the first 25 minutes or so, until the frequency is blocked by RDP which signs on in Portuguese at about 1555 on weekdays. The broadcast starts at 1530 with IDs in English and Hindi, then music, mostly introduced in Hindi until approx 1546 when there is a short news bulletin in English followed by music introduced in English (at this point the frequency is blocked by RDP). The English ID is "Radio Ceylon calling out to India". It seems to be a relay of a domestic channel with various FM frequencies announced, including 95.6 MHz in Colombo (WRTH lists this frequency for SLBC commercial service in English). Reception is only possible here Monday-Friday at 1530-1555 as the channel is completely blocked by RDP in Portuguese on Saturday-Sunday.
