147 Q  716 points 15x W  3x VE   best DX was 22 points best  signals from EM main grid. P4/DL6RAI FK42  one of the best (few) DX signals  but total deaf for EU calls. Very weak TA signals absolute the poorest propagation ever during a SP here. Never happened before  not one RBN  spot in W. Now a Beverage 450m in direction West high expectations of it. The first RX tests at 630m looked very promising. G's  from West came in 6-10dB stronger compared to the TX vertical. But something must have changed since I could not reproduce that first good results. In the SP the Beverage was not better then the K9AY So I have to check in the field. Stew Perry  Alleen de nacht van zaterdag op zondag meegedaan Ivm TVI  op de  KPN Motorola 1863 kabeltuner. 160m zeer matig deze keer zwakke signalen uit W 15x en VE 3x De Beverage richting west viel ook niet mee de K9AY won het. 4M   70MHz 70MHz  XVTR weer aanges...

XDR  S3HD De hele tuner bestaat uit een paar simpele filtertjes. De 2 NXP ( PHILIPS)  chips bepalen de eigenschappen. and inside you'll find the NXP TEF6730/SAF7730 radio chipset and several adjustments. The HD module contains an SAF3550 processor and a 16MB SDRAM. een zeer goede review hier http://ham-radio.com/k6sti/xdr-f1hd.htm The XDR-F1HD uses advanced digital signal processing algorithms to dramatically improve reception of FM signals corrupted by noise and interference. Threshold extension  suppresses the impulse noise ordinary FM detectors generate for weak signals. The obtrusive character of this noise quickly degrades reception quality as the signal level falls below a threshold. The impulses arise from detection-vector phase reversal due to additive noise peaks. High-performance satellite and terrestrial microwave FM links have long used various threshold extension techniques to enhance performance. Tracking filter detectors that...
