Welcome on the PA7N site!
Hello, my name is Erwin and this site is about my amateur radio hobby. I am A ham radio amateur since 1985!
My QTH is Nes near Akkrum/Leeuwarden. The province Friesland in the north of the Netherlands. The locator is JO23wb. Things I like in amateur radio: HF, QRP, QRP-kits, CW, antennas, antenna tuners, homebrew, microcontrolers, software development, Linux, 6 meter DX, meteorscatter, Software Defined Radio, DSP, old tube transmitters and SOTA (Summits On The Air). My main equipment is An Icom IC-7200 and An Elecraft KX3. My antenna is A Dipole 2 x 17 meter. Feed with open line. Tuned with an double L tuner (homebrew). So the picture on top of this page is not up to date anymore.
Please do leave A message in the guestbook or send me an email. My email address erwin (at) pa7n (dot) nl.

|This weekend SOTA activations|
Summits On The Air - donderdag 27 februari 2014 19:36
|This weekend (1-2 march 2014) I will try to activate some SOTA summits in Belgium. Depending on the wetter and other activities I will try to activate ON/ON-001, ON/ON-010, ON/ON-011 and ON/ON-013.|
I will be QRV in CW on 30m around 10.120 MHz. As I am still A beginner CW OP please be gentle with me. 15 wpm with a little more pause between the characters will do :-) Please no pile-ups!
I'm using A Elecraft KX3. 5 Watt output. 10 meter fibre mast. End feed half wave sloping antenna. 5000 mAh LiPo battery. QRP Long wire tuner.
If 30m doesn't work I will try 40m on 7.032 MHz.
Hope to work you!
Things didn't work out as planned! In the car, on the way to the holiday park, my wife told me she had booked a different park then what I thought the holiday park would be! (Amazing isn't!) The park she had booked was more to the west of Belgium. There was only one sota summit with more then one point. So no high score that weekend :-( But still a lot of fun :-)
The summit I activated was ON/ON-006 La Croix Scaille. It was 55 km driving. Walked about 2km. After 30 minutes transmitting it started to rain. I had to quit. The new KX3 worked great!

I have downloaded your software "PA7N VNA" v0214. I am using a MiniVNA with WinXP Pro. I have a couple of questions.
When attempting to view a parallel resonant circuit using your software, how
does one determine the exact frequency of resonance?
I am currently trying to use the MiniVNA to accurately cut 1/4 wave stubs to frequency and am not sure of the correct proceedure for doing so.
Can you help?
Also, is there manual online for the use of your software?
Thank you for your attention. I appreciate your time. I look forward to any comments you may have.
Warm Regards, and 73,

Cathy Jo Erwin July 14, 2012 I am a new Landlord who has taken over several ppeeortirs, Most of my renters are on housing assistance. I am looking for some sort of grant to help me fix these ppeeortirs up, the former owner has not done any repairs to any of the ppeeortirs in over 2 years and they are all in bad shape. I cannot afford to fix them all as fast as they need to be fixed. Please help me find some sort of Grant to help me make a better living condition for my low income tenants. They need roofs, water heaters, one needs a furnace, bathroom sink, faucets in kitchen, stoves, refrigerators ect They were so poorly kept that Im suprized that housing did not shut that guy down. I need help to help my tenants so they do not become homeless. </a>
