Pete Pete n Buster
I am a retired telephone splicer (April 2007) after 40 years with AT&T. First licensed in 1965 as WN8VVG and WA8VVG, Now W8VVG. I enjoy playing with my trained Lab, Pete (K9-LAB), hunting, archery, model RC planes, flying Light sport planes and motorcycling.
I was inactive for about 15 years until I retired. With a little push from W8UVZ, K8GG and W0CD I am now active on 80/160 cw chasing DX. I also hang out on 1.871 with the 1721 bunch evenings, a very friendly ragchew group.
After many years of casual collecting QSL's, I got serious about. I just received the DXCC award part of which is 165 country's worked on 160 cw with 149 confirmed. Most confirmed on LOTW.
I have a great wife Rosemary, 3 kids, Ryan, Trevor and Lacey. 6 grandkids, Jordan, Hunter, Jacob, Mikalya, Chase and new arrival Gerad 9/6/2013
I was recently honored to present the 160-10 meter small lot Waller Flag RX antenna (see below) at the 2011 Dayton Antenna Forum. Thanks to all who attended and the kind comments. See www.kkn.net/dayton2011/N4ISwallerflag.pdf for the presentation or www.k3lr.com and then Dayton 2011 antenna forum. Thanks to NX4D and N4IS for all the advice and help.
I extended the boom to 28' with 6' separation. The loops are now 21.5' X 11'. Then moved the phasing box and phasing leads to the tram to make it easier to work on. The phasing leads were then twisted at 2 turns per foot coming down the mast. I am pleased to say the Waller Flag is working better than ever. Quieter with a slightly better F/B. It seems to hear better than before.This antenna works really well on on all bands for RX. A good preamp is a must for 160 and some gain is necessary for 80, but no preamp is necessary for 15 thru 40 meters.
Gary Nichols KD9SV has been instrumental in devolping ultra low noise preamps for the Waller Flag. Without his much appreciated expertise, weak signal reception was only done by ganging exsisting 20 db preamps thus increasing noise. With his devolpment of 35db plus ultra-low noise preamps (5x pHMET) the Waller Flag RX antenna has really came alive for the urban small lot ham These preamps are also very good for flag, pennants or other low gain RX antennas. One more note the 5x pHMET is too much gain for the beverage RX antennas, also a front end saver is a must for most modern rigs. Gary has devolped other ultra low noise preamps for the beverage type RX antennas. See DXPedition II.
Thanks Gary for all your help
Currently getting setup for 6 meter DXing. Just finished a Home brew 6 element LFA yagi. http://www.g0ksc.co.uk/. The the next project is converting a SB 220 to 6 meters, should be interesting.
The SB 220 conversion went better than expected. I purchased a SB 220 that had never been completed and was super clean. After fixing many cold solder joints and removing the original builders mods, the conversion went well. The amp had never been powered up so I replace the filters and diode board with the Harbach upgrades. Then added the Harbach soft key and soft start, modified the Heath tune and load caps, built the parasitic suppressors from nichrome ribbon and wire and wound the tank coil from 1/4" copper tubing, built the tuned input. Many thanks to AG6K for the info and parts for the parasitic suppressors, grid, cathode and HV protection.
I was very pleased when the first time firing up the amp all looked good. I let the filters cook for several hours before applying HV to the tubes, the let the tubes cook for a few hours. First time putting RF into it showed 400 watts out with 25 watts of drive, tweaking up the drive 70 watts was 950 Watts out, haven't pushed it beyond there. Tuning is very smooth, with only the tuned input control a little touchy. A SB 220 conversion is a fairly simple and inexpensive precedure with a little research. It can be done in only a few hours, depending on upgrades necessary. Email me if you have any questions. Most of the conversion was done according to the April 2008 QST article
