Normally VK7CW, Steve San is solid on both bands but was weak today. So the band conditions were really poor.

VK7CW reported about OS0S as follows.


At 0928utc OS0S Leon called into the net on 30m and was heard by VK7CW at 339 but he failed to respond to any calls.


I didn't hear OS0S at all.

I did QSO with ZL station using 400w + windom antenna at RST579 around at 0700utc on 20m. I think the band condition seemed to go down afterwards.

Thank you for the net QSO, dear Steve San.
I hope to see you next week.

10149.0khz was used to avoid QRM and very clear, no QRM in result.
We will try this frequency again next week.

VK5EEE, Lou San tried his QCX qrp trx and was successful in making QSO with me.
And I received the following e-mail from him.


Dear Yo San, Thanks for FB nets. 14349: VK7CW RST 119, JL1MUT 569 QSL 569 with my 75W due to smaller Power Supply not giving enough amps for 20m TX
My 3W from QRO rig was RST 229 10149: JL1MUT 0930-0936 RST 569 my QCX QRP 3W RST 229 0936-1006 JL1MUT RST 569, QSL 569 with 100W (30m I can get full power from smaller Amp) Big Amp is needing repair. 1006-1012 JL1MUT RST 56/79, QSL 339 peaking 439 with my QCX QRP 3W.
Very good fun with QRP, the receiver is better as it has nice narrow 200 Hz filter.
It is full QSK and has many features, see: http://qrp-labs.com/qcx.html The frequency 10149 was very nice, even with wide filter on big rig, no QRM.
I was heard in Europe on QCX using WSPR with 2W. On CW I had QSO to Timor 4W, USA and DU9 and now JA.
Very 73 and hope to see you again tomorrow.


Thanks for the net QSO, dear Lou San and dear Steve San.

Higher voltage and thus higher output power could be achieved thus, in addition to optimised coil turns on L1-L4 and spread out nicely and checking C25-C28, C30 as they're equally important:

Hi Enno, Fred, all

There are two things which I think can increase power output. Talking here, on the assumption the transceiver is already performing properly i.e. correct LPF etc. I expect Fred is referring to the first of these two:

1) QCX uses a PNP transistor Q6 to shape the RF envelope on key down/key up to remove key clicks. There is a voltage drop across this transistor as usual. If it is replaced by a P-type MOSFET with appropriate other component value changes, then this eliminates most of the voltage drop. Since the Class-E PA then runs at a little higher supply voltage, it produces more power output.

2. Use of a MOSFET circuit instead of the schottky diode for power supply reverse polarity protection increases the component count slightly, but also has a much lower voltage drop, again providing a little higher voltage to the PA.

I don't know of any disadvantage to doing these modifications, they should work fine.

Steve San has a fan dipole for 160, 80, 40 and 30m.

We checked his fan dipole on 30m. The noise level seemed to be improved on his side when using the fan dipole  though the signal strength was down overhere.

I also had some intermittent radar QRM on 14349.0khz.

The following VK5EEE's report is added.

My report for Steve San VK7CW on both frequencies was 599, at one stage he was 599+25dB — we had great path today.

Thanks for your report, dear Lou San.

JL1MUT/Yo

VK7CW, VK5EEE and JL1MUT checked in.

JL1MUT reports the result as follows.

I was not available for 20m.
Because my 20m yagi antenna is still down on the ground for the typhoon.

I checked-in late.
Because I made a QSO with VK3IM, Tim San on 10119.0khz until just before check-in the net.
I had received e-mail about Tim San from VK5EEE, and Tim San has the trouble with his phone because a power outage damaged his router.
I had found his calling CQ QSK at 0911utc.
He said that the trouble will be fixed replacing the router tomorrow.
I hope that everything is OK for him tonight.

And the following report was received from VK7CW.

0900utc 20m 14349 running 100w into Hex Beam (north west) with HB Steel Ruler Cootie

I called CQ SSN for 10 minutes on 20m with nil replies. At 0910utc I QSY'd to 10121.5

0910utc. 30m 101215 running 100w into inverted vee antenna:

I called CQ SSN and worked the following (non SSN) stations:

0913utc F5UQE Duc - 339 both ways. Was also using cootie and we exchanged SKCC numbers.

0922utc S57V Milan - He was 579 but gave me 599 report

0926utc KC4HCH Roger - He was 449 and gave me 429. Exchanged SKCC numbers.

0930utc SSN - VK5EEE Lou - He was 579 and gave me 599

0936utc JL1MUT Yo San - 579 both ways.

Excellent conditions on 30m tonight and the net ran from 0930utc until about 1010utc. 
At the completion of the net I then worked JH1RZY also with RST 579 both ways.

Thank you Yo San and Lou for a very enjoyable SSN on 30m. It sure was a nice change to hear Lou and be able to work everyone on the net. First time in ages!

I hope the conditions will be as good or better next week.

Best regards to all from Tasmania,

Re: EU-VK propagation by DL1YAYDL1YAY, 29 Sep 2017 07:01

At power-up you are asked to select the band. All this does, is default the power-up VFO A, VFO B, Preset frequencies, alignment freqeuncies, and beacon frequency to a frequency 20kHz above the lower band edge of the chosen band. It does not do anything else to the configuration. If you want to change the band you can use menu item 3.9 to reset these parameters to the new chosen band; or, you can just use the rotary encoder to tune there, or manually set presets to the new band and load them into the active VFO. Lots of possibilities. But a new firmware chip is NOT required.

Three circuits have band-specific components:

1) Output low pass filter, for transmitter harmonic suppression. If you don't change that then you will either have too much fundamental attenuation (if your transmit frequency is above the filter frequency; or too little harmonic suppression (if your transmit frequency is too far below the filter frequency).

2) Input band pass filter, that protects the receiver mixer (to some extent) to strong out of band signals. If you bypass it, everything will still work but at the expense of impaired intermodulation performance since everything across the frequency spectrum will hit the mixer.

3) Class E PA resonant circuit: if you don't change it, then the transmitter PA will operate at lower efficiency; which will mean it will dissipate more heat. It may eventually lead to frying the BS170 transistors.

"Multi" Band by VK5EEEVK5EEE, 26 Sep 2017 09:36

The result is shown as below.

VK5EEE, VK4BGR and JL1MUT, 3 stations joined the net.


0858 - 0932utc
14349khz

VK5EEE
JL1MUT 589
VK4BGR 100 NIL

VK4BGR
JL1MUT 589

JL1MUT
VK5EEE 579
VK4BGR 577

The band condx was excellent on 20m tonight.
I guess that VK4BGR, George San had the trouble with his transmitter.
The response of his transmission was not smooth and the ripple was heard on his signals.
VK6RR, Roy San received my signals at RST549 but I guessed that his noise level was high.
VK5EEE, Lou San told me about it for the QSP. I guess that Lou San communicated to Roy San through the inter net.


0933 - 0944utc
10121.5khz
VK5EEE
JL1MUT 489 career QRM

JL1MUT
VK5EEE 469 career QRM

We had career QRM on bothside and QSY back to 140349khz at 0945utc and kept the QSO until at 0953utc.

This late afternoon, I worked LZ, OK, I, HB9, DL and EA via LP at 0700 - 0830utc before the net.
20m was so excellent.
I hope to hear Europeans on the net.
