0633Z 136.5 Spectrogram 1365AC Note 1&2
Notes:
1. Spectrograms made with NRD525 receiver and Burhans efield probe 17
JAN at 0600-0700.
2. Spectrogram 1365C was made with receiver tuned first to 137, then
136.8, then finally 136.5 showing spectral line at 137.1 kHz that was
observed with the Cubic receiver and spectrum program on that setup.
3. A few static crashes heard all evening but lots of quiet period in
between them. The site is really quiet with regard to power line
harmonics. We are about 1/2 mile or more from any power lines. We
seem to be far enough away to achieve our goal.
4. Signals on the beach seem stronger than at the house.
5. Some NDBs were heard through the heavy QRM din common to this band
and frequencies logged were where they were heard and when looked up
were listed at a different frequency. The listed frequency is in
parenthesis.
6. All 3 lowfers are clustered in the Pittsburgh area, observed off
and on with propagation changes. It is curious that no other lowfers
were copied this night. Approximate distance using a ruler and
scaling is 367 miles. There were no closer lowfers that we could
hear. We tried specifically to hear RL at Herndon VA on 181.62 kHz
without hearing it. Other GA, NC and VA lowfers were listed in the
Lowdown but were not heard.
18 JAN 1988
Notes:
1.Noise, Noise, Noise. The noise is awful. Can't hear anything
worthwhile.
2. Spectrogram ran on the Loran-C signal to see line structure.
Saved as 100_05.gif.
3. Later weather reports relate tornadoes in Arkansas and
Tennessee. This QRN is similar to that heard other times on HF with
tornadoes. When tuned to the HF bands it was not heard probably due
to propagation. It is continuous static crashes at an unusually high
rep rate. Seems to be characteristic of tornado bearing storms (super
cells?) on both HF and LF.
