Re: What effect does full moon have on radio reception?

 

I am still learning about this and a lot about radio in general. I don't know if it would have much impact but I would also love to know the answer.

"What effect does the Northern and Southern light/aurora have on nighttime am reception?"

I have heard a bit about him, does he post on here much or does he also have a webpage? How do you post something like this?

Thanks Paul,

Paul W. has earned his DXing status the tough way, fighting subfreezing cold in order to explore breakthrough Arctic propagation. He deserves all the help he can get, and he should run wild again this winter.

Read about gray line propagation.

Re: Counterpoise question

I am not sure how that would work but it is worth a try I guess.

Question: how long should the countpoise be? As long as the whip antenna? As long as any antenna attached to the whip?

Re: [irca] TP/TA DX

Have you had any luck with Turkey on 954, Paul?   That's made it into Victoria a couple of times.

Although 1215 is the "early warning" here, once things deepened a bit last season, Romania and Spain did reasonably well at times, as did the Egyptian on 864.  In midwinter,  Iran was possible with some effort, and on Iran's best nights, British stations weren't as noticeable, a bit more like what you've been finding in Alaska, perhaps.

Even the guys in Vancouver/Victoria and other parts of western Canada get some smatterings of Absolute 1215khz and I know it's pretty common on the east coast.. at night. I've heard it a few very scant times, very weakly.

My most common on 1053 isn't Talk Sport but .. Romania. .and it has to fight with the 3rd harmonic of my local airport beacon, running 1kw on 350khz from 2 miles away.

My most common 1089 is Talk Sport and its not that common, because it has to fight with XEPRS Tee-huh-wanna before sunrise. One day Talk Sport 1089 was bombing in like a local for 15 minutes. Audio: https://drive.google.com/file/d/1h0qOCPxIr4srPPoF1DvwFtT6Iyrid3mk/view?usp=sharing

I've heard romania on 1179khz a few times as well. 

Two of my surprising semi regulars were Iran on 1026 and turkey, with awful audio, on 1062khz.

One of my surprises was the 20kw Radio Dechovka from the Czech Republic on 1233. Kinda weak and noisy but good on fade ups here: https://drive.google.com/file/d/1oq1ZkeXjoONPRU9-ChSJpg5LByawIn7_/view?usp=sharing

Re: Counterpoise question

kevin asato
 

The CC Pocket does something similar with FM reception. They either use the headphones or a special lead to the ground side of the headphone jack as a counterpoise. It definitely does aid RM reception; not sure how it would enhance HF bands as it have to be considerably longer to be effective. The enclosed counterpoise is 31" long which is about right for the FM broadcast band. I cut off the encapsulated end of the counterpoise and added an alligator clip to extend as required. You may need to do something similar.

Jock,



A counterpoise some distance from the house will help close to  its natural frequency.
It can, however, be tuned like an "earth tuner" to cover a wide band of frequencies.
This may or may not help, as it might "attract" noise from nearby appliances.

Also, it will introduce imbalance as the telescopic antenna would remain "untuned".

Look for "earth tuner" on the dreaded web and experiment!

The best solution  remains the FSL optio reception  for medium-wave
and a tuned frame-aerial for shortwave.+

Re: AM DX'ing Quest

kevin asato
 

In the spirit of Ultralight Radios, NO. Passive techniques only. This is why you see/read use of external loop antennas of various types. However, you can on your own as there is no one to police how you actually receive. It's all on the honor system here. Select Upper or Lower SB (or just SSB) and tune around for the best signal for the frequency of interest. This would be similar to using an external variable oscillator or Q-multiplier in which you inject another signal in attempt to recover the original signal. By inject, it is sufficient enough to couple the output of the oscillator to the radio using a few turns of wire. Try 1 or 2 to start. YMMV.

I hope you took note of the precautions Max? :)

Note:
1)Please avoid high press, strong collision, drop or water.
2)Don't place radio under sunshine, high temperature, high humidity area or store radio at environment of temperature < -5℃ or >50℃.
3)Don't clean case with chemical solvent to avoid damage of radio casing.
4)Don't disassemble the radio or change specification of inner part radio.
