This is getting to be spooky, someone somewhere does not want me on 160m
Hi to all members, I have received the ATmega V1,6 (thanks Steve) and have inserted it the correct way round but there is nothing on the display (totally blank) when I insert the old chip the display is normal (except for the cycling of course) I just can not believe the bad luck I am having with this time.

WSPR beacon with the "old" QRSS kit
Hi,
I have finished modifying my 30 meters QRSS kit into a WSPR autonomous beacon using a TI Launchpad with MSP430G2553 (4,6 USD micro-controler kit).
Here some pictures and more details (in french but you can use the provided automatic translation) :
Reports have been good with up to 6000km with the 90mW of the beacon. I will have to raise a little bit the PA supply voltage in order to get a little bit more power from the BS170.
The beacon is now running for 4 days showing no significant time drift without GPS.
I still have to do some clean up in the code but I will soon publish the code and a schematic. The Launch Pad is really cheap and the ability to reprogram it on the fly with the USB port allows you to virtually transmit any waveform. The other parts cost less than 2 USD.
73,
Yan.

Re: Ultimate QRSS: problem with set-up menu
Hi Hans,Steve,
Today the new processor arrived, I installed it and everything works well. Setting up is a breeze now.
Still don't know how the eeprom got corrupted.
Now on to the GPS module, I m going to use an old Jupiter board.
Thanks or the great service and a great kit.

Re: My PA keeps blowing UQRSS Kit << Help >>
I hope you've had some success but a sideways look at this might suggest you could have replaced the first failed PAs with 2N7000 and installed them as BS170. You do say that this happens when: If I put a jumper between the 5v connection and the PA connection therefore supping the PA with 5v the transistors heat up within a few seconds more or less the same as when supplied with 9v. Therefore I have a fault somewhere. rgds lowemmission@ --- In QRPLabs@..., "G1IVG" <colinlowe_home@...> wrote:
The two BS170's are installed correctly (180 degrees compared to the original 2n7000). I have had them in the kit for over a month and it's been working more or less 24hrs a day since with no issues until I unplugged the kit and plugged it back in yesterday when they blew. They blew more or less 15 seconds after re-applying power. Then when I installed the new ones, they also heated up very quickly and I pulled the power plug out before any damage was done. I have double checked and the transistors are mounted correctly (180 degs).
It's as if there is a short, but I just can't find it which is frustrating as the kit is fairly straight forward. All components look fine and the PCB has been checked for shorts and all looks fine.
I'm wondering is IC2 74HC00 has a problem as it's really the only bit I haven't changed.
To confirm I only get the problem when either 5v or 9v is applied to the +PA connection. If I leave the +PA connection floating and just 5v connected to the 5v Supply connection the kit works fine apart from the much lower RF power output.

Hi all,
I built my 30m Ultimate QRSS kit over a month ago and it's been working fine until last night. When I unplugged the kit and plugged it back in again after about 15 seconds I heard a pop and a burning smell and the LCD display just had black squares across it.
On closer inspection the PA transistors had blown and either they or the fault that caused them to blow was also dragging the power supply down causing the display problem.
I have been running the kit for the last month from 13.8v PSU then through a 7805 voltage regulator for the 5v supply to the kit and also the GPS, then for the PA I come from the same 13.8v supply to a 7809 voltage regulator that supplies 9v to the +PA connection. This has been working fine for a month until last night.
After it blew, I removed the two blown transistors and installed two new ones as before. I then powered it up and noticed the transistors heating up and starting to smoke !!!!! I quickly removed the power.
I have checked the PCB for shorts and all the capacitors and coils etc. but can't find any short.
If I remove the 9v supply from the +PA connection and just have the 5v going to 5v supply connection with nothing on the +PA connection the transistors stay cold.
If I put a jumper between the 5v connection and the PA connection therefore supping the PA with 5v the transistors heat up within a few seconds more or less the same as when supplied with 9v. Therefore I have a fault somewhere.
If I remove IC1 (ATmega168) from its socket and with the jumper installed as above, the transistors heat up in a few seconds.
Is it possible that I have blown IC2 74HC00 as that's the only component I have not checked.
Looking for any ideas or other tests I could do to identify the problem.

Re: My PA keeps blowing UQRSS Kit << Help >>
Have you measured the output voltage of the 7809? The fact that the problem doesn't happen when the higher voltage is applied to the PA suggests to me that there may be an issue around the regulation on the PA supply.

Sorry to hear your bad luck.?
As has already been said, if you are using BS170s as a replacement for the 2n7000 they fit the opposite way around. But I am sure you won't have made that mistake.?
Are you sure that your voltage regulators are intact and the capacitors each side of them are ok and of the right value.? Are you sere they are delivering the correct voltage under load?
When you unplugged the beacon did you switch the power off first? Do you have a way of measuring the current into the beacon if so what is it?

Re: I am having trouble with the UQRSS Kit for 160m, any advice would be appreciated
Hi Philip and all other members,
I have not found any solder splashes or other mistakes on either side of the PBC, this is something I will now have to check with the circuit diagramme and multimeter (maybe a piece of wire under the ATmega ic socket)removing the 5v to PA bridge has stopped the cycling so it is as you said Philip PA related, I can also confirm that I also have the div by 8 bug as the seconds were not changing in the display.

On mine I once by mistake left a wisper of wire shorting the output of the PA.
On switch on it would cycle between mode and welcome screen...
So Colin, double check for any shorts around the PA...
Hope you fix it..

Hi Colin,
What you have described partly might be explained by a lack of capacity
from your batteries to power the beacon on transmit. So there might be
something wrong with the power supply or the PA. I have never seen the
cycling between the welcome and transmit screens before. I suppose this
might be explainable by the power supply lack of capacity as if the voltage
drops below a certain level the microprocessor will shut down and if the
voltage rises again it will switch on and display the start up screen.
The sure fire way of checking to see if you have the "divide by 8" problem
is to see how fast the clock runs when you set the time.

Hi Hans,
Okay, I will do that, thanks for the quick response.

Re: Ultimate QRSS: problem with set-up menu
Hi Paul
What you describe sounds typical of what happens if the EEPROM gets corrupted. Please can you order the v1.06 free upgrade from Steve at the shop??

Hi,
Today I have build the Ultimate QRSS kit (30m version).
Building it was easy, xtal is running and the display shows welcome message at start-up.
However, set-up is not possible. Both buttons are working, I can step through the menu and change values. But, in many menusteps the order of character editing cycles a whole lot
more characters
then the order of characters that are mentioned in chapter 6.2.3 of the
instructions manual.
It seems that the whole characterset of the LCD is cycled (200+
chars..). After I stepped through the whole set, the only desired
charactersequence is selectable but by the next character it's starting
all over again.
In the menusteps Frequency, GPS baud, AF freq, FSK Adj and time, I can not select a comma or double dot. So, I can never set these values up right.
After entering a value in a particular step, this value is also displayed in the next step, is that correct?
When I press the right button at the end of the menu I get an message "error: speed". It's like no data was stored in the EEprom. Could this also be a symptom of the :8 clock problem?
I have checked for possible shorts on top and bottom side but could not find anything wrong.
Any idea anyone?

Paul PE1OKU
