The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

'allo,
I am using a FT2000 and have noticed that the TX power varies greatly over the 2 min cycle. The power appears to change with each change of tone. It can change from 5W down to 0.5W over the cycle.
Is anybody else using an FT2000 or has anybody else seen this.
I know that the FT2000 is very sensitive to the frequency of the audio of the input signal. (Even the type of voice).

I was WSPRing on 10m for many hours yesterday and received a few big signals, but no body received me.

Thanks

'allo,
I've been having a blast recently using WSPR.

The highlight was receiving T61AA for about 2 hours AROUND MIDNIGHT on 10m. This is a path fo 5555km.
He started off around -14dB and over the 2 hours decreased to -26dB. I checked with him and he confirms that he was active that night.

Yesterday I put up a 5/8th wave vertical for 10m ready for the activity day. I was going to do 80m during the night and 10m during the day, I think I will now stay on 10m for the 24hours.

Maybe RX only , (see my 'FT2000' blog)

WSPR is quite an interesting mode for doing certain
(scientific) experiments. Data integrity is important
when digging into a database. I have been enjoying
reception of mainly 10 MHz WSPR-signals for 10 days.

UNBALANCE IN THE LOOP
---------------------

I currently use a 28Mhz quad loop which is taped to the spare bedroom wall indoors.

I had forgotten just how unbalanced the system can be whilst using an experimental tuner I had made for another purpose. Several years ago I made a balun for it, and it made a huge difference, both on tx and rx.

Having recently resurrected it's use for tx purposes my memory is coming back.

WSPR has only highlighted what I should have remembered.

I'll dig out my old tuner/balun config during the week, which will enable
me to use it as a mag loop for the LF bands too. Despite only being wire,it used to
work VERY well, and didn't melt with high power either ;-)

28MHZ FLOPPED TODAY
-------------------

I left my WSPR beacon on for most of the day. All I got was one measley cloud of SpE, but very good signal strengths for a short time.

Having seen a fair few G stations monitoring, some just outside of ground wave
range, I was hoping to see some possible MS or aircraft scatter reception occur.

But nothing happened. However I will persevere,as these sort of tests are far

Trying WSPR for the first time today - some initial issues with Vista crashing but seems to have settled down now.

Using Microham MK II soundcard and seems to work fine - my erp is very weak as I am using a 20m mobile whip antenna on 30m, but without any radial plane - just working against the ATU in my TS570D. Reason being, my main antenna - Froce12 Sigma-5, is in bits currently awaiting replacement parts.

Hope I am doing all I should, and not doing what I shouldn't !

As I already mentionned, the WSPR DB is far too unreliable to attempt any serious propagation study or to trigger any propagation alert (ie for multi-hop E's on 10/6m)...

Here is an example among many others

Locator square finally corrected.

Also I am currently using a wire loop antenna, and it's weird how
I'm being received in places that should be directly in the null of
the antenna.

If anybody knows a simple way to get a IC746PRO to put out less than 5W - please let me know. The next step for me would be to build a precision power divider. I would really like to get it down to 1W or less.

Bad day for WSPR here in UK on 20m. RTTY contest hooligans all over 14.0956. It's all quiet again now so I'm back on 20m

I can see nostalgic reasons why some people might want to operate RTTY, but contests for this obsolete mode - WHY???

That happеned during last WSPR activity period (12 August) on 40m band. Once I've noticed the following sequence:

2009-08-12 22:14 UT2UZ 7.040190 -20 0 KO50cr 2 VK8CH PH57 11836 90
2009-08-12 22:14 UT2UZ 7.040147 -8 0 KO50cr 2 VK8CH PH57 11836 90
2009-08-12 22:14 UT2UZ 7.040104 -20 0 KO50cr 2 VK8CH PH57 11836 90

The first idea, came into brains, was that something wrong is with my equipment.

However, more triple sequences were seen that day:

New here so if I am doing anything wrong, please please let me know.

Currently suffering terrible local QRM from PLT, so recieve is very poor.

I'm back on WSPR now from Sydney.

I'm unable to engage in any other radio related activity due to other commitments. I wanted to still be involved so WSPR is it for now.

I've varied the output from my IC-703+ from 0.5 watt to 10 watts. As I am utilising the internal ATU I can only go by the power output reading on the radio. Output from the radio may in fact be less than 1 watt.

Does anyone know how accurate the "Po" (RF power output) reading on the IC703+ is?

Given the nature of my less than ideal non resonant wire I would imagine that radiated power would be minimal. Also, I've only had limited success with receiving signals from overseas (other than NZ/ZL). I've picked up 4 or 5 from the US, and the same number from Europe including the UK.

When I increased my radio output to 10 watts I was received by a couple of stations in the US. Other than that it's only been the east coast of Australia and a couple of spots by NZ/ZL stations. I'm being spotted by some NZ/ZL stations tonight with the radio set to .5 watt max output. This is fun!

I will be primarily operating PSK31 and other digital modes on 30m through the weekend but will WSPR when taking a break from the keyboard or operating voice on other bands. See http://zl2adr.webs.com/
