Is this the updated version of the Super Flux Capacitor of the 1980's?HuhHuhHuh 73 K1WJ

If everything is correct, it should be working better with 100w vs 7 watts. Hook up your old radio & see if you can hear yourself on 20m, can hook up small wire for antenna. Use lowest power to check signal & audio. Check new radio with dummy load. Make sure your in USB for 20m voice. 73 K1WJ David

468/14.250 will get you in the ball park = 32.84ft, then divide by 2 for each leg = 16.42ft

Any paint without metal -bought spray can at hardware store, painted mine tan to fit in surroundings - I think they make Camo also. Look at the background behind whip & paint it that color. I'm in the same HOA BS. 73 K1WJ David

Glad to see you got a 100w radio - wise choice for starting out.
Last week contacted a QRP station that answered my cq call - after 3 replies I got his call, 3 more times to get his name & state.....after that stated 73's & hope next time we contact I hope you have a 100w radio......
Contacts can be difficult at times on 100watts especially if your antenna is not ideal for the band in use. Next time you make some contacts with 100 watts, at some point in the QSO turn down to 5watts & ask the other station to do the same, you will see what your missing.......73 K1WJ David

Last I knew it was still E=IR, V for voltage - no big deal, still calculates the same. 73 K1WJ David

How about a MFJ 6m hamtenna dipole - 2 mobile 6m hamtennas on a dipole mount, good swr for all of ssb section & great efficiency - simple & easy. Total price $50+-. Run some 9913 coax as short as possible to get the job done, 2-3 turns on 4.5in form for coax choke close to feedpoint.

OK, did not mean to make you feel bad - are you using ladder line or coax with G5RV?
If coax at radio, about 6-8ft from radio - take coax & put 10-12 turns around a 4.5 inch form to create a choke - I think this may help. 73 K1WJ Cool

Easy: Since your a Tech. go back to the 10m dipole - Fixed. 73 K1WJ Grin
10  eHam Forums / Elmers / RE: Tuning Multi Band Antenna on: April 17, 2013, 03:06:03 PM
A rigid trap dipole is the same as the Hustler 4BTV vertical
Because the 1st section of tube & trap from feed point is 10m.
The adjustment of 10m will effect the adjustment of tubes & traps for the lower bands beacuse they are additive. Look up the cushcraft D3 install instructions = a trap dipole.
Again the Hustler 4btv vertical install applies the same principals.
Just do it..........73 K1WJ David
11  eHam Forums / Elmers / RE: Tuning Multi Band Antenna on: April 17, 2013, 02:06:56 PM
Start at the bottom of the antenna - 10m then 15m then 20m then 40m. Go to DX Engineering site & down load the Hustler 4BTV install instructions - that is how you do it, your dimensions will be different but basic principles still apply. 73 K1WJ David
12  eHam Forums / Antennas and Towers and more / RE: multi-band vertical on: March 27, 2013, 09:30:50 AM
I have a 20m vertical with one elevated 20m 1/4w radial 4ft off the ground.
The radial is to the east side, make just as many contacts to the west.

How high will antenna be?

Ground mounted allows you to put as many radials & length that will fit.

If elevated 2 feet or higher at base of antenna, one 1/4w radial per band will work, even if all all on the same side, fan out a few inches from each other.

14  eHam Forums / Antennas and Towers and more / RE: 40m 1/4 wave vertical what to expect on: March 11, 2013, 12:49:19 PM
On 40m with 40 1/4w radials should work real good, more in the clear the better, - would not expect too much out of 17m or 15m. 73 K1WJ David
15  eHam Forums / Station Building / RE: Considering a new rig - Contesting/DXing on: March 08, 2013, 07:43:39 AM
I also have a TS-50 - just keeps on ticking.......
TS-50 to a TS-590s sounds like the perfect upgrade - can not go wrong for price/performance.
