I'm going to try my hand at weak signal VHF.

I'll be putting this up @ 75 ft

What are your experieces with VHF?
I really don't know what to expect.

I saw that listing. Enjoy!

I had picked up the older Kenwood mobile multi-mode 2 meter rig, but it got sold off when we lost the previous QTH. But one day!

Without enhancements, I would say that contacts out to 100-300 miles is typical, depending on height of antenna. With enhancements like tropo and Es, it could well be 1500 miles+.


I can only offer the following anecdotal experiences. These may not be typical where you live.

From 100 feet ASL, with an 8-element beam, and 100 watts: Claymont, DE to Kansas City, MO. That's about 1,000 miles.

From 400 feet ASL, with a 13-element beam and 50 watts: Wilmington, DE to Huron, SD. That's about 1,200 miles.

Both of those cases were due to enhancements; either tropo, Es, or a combination.

YMMV

ASL (Above sea level), or AGL (Above ground level)?

I only ask for clarification, because I can foresee you having a 400 ft tower :)

Running just 50 watts SSB on 2 meter with the FT 847 and Flexa 11 element beam at 55 feet above ground Sporadic E Europe, 1100 km's Italy from here the Netherlands, France, Germany, UK, Poland, Finland, Ukraine ( 1560 km) Sweden, Spain, Ireland, Portugal, And Switzerland, just this year.

The beam has 12.8 dBd, coax loss is 0.7 dB ( Ecoflex 15 extreme low loss 5/8 ")

Good condx will go from 800 - 1900 KM or further here, daily reach with a station with decent antenna is 400 Km's ( Ruhr area)
N Connectors throughout the station on 70/2 , for 70 there is a 23 element Flexa yagi with 15.4 dBd.

Higher = better, no direct trees or buildings in your path is a must.
Adding a low noise pre amp near the antenna will enhance your weak signal reception.
Get a decent amp, 200 to 500 watt i use a homebrew transistor amp with 2 x the MRF 247 build 25 years back.( Class AB1)
It's addicting.... i know ;)

Tropo ducting is common on 2m SSB between SoCal and Hawaii during the late summer--2700 miles.

It's not a typo. ASL

AGL would have been no more than 25 feet in either case.

Wow! I've got some faith for my setup now :) Seriously, I figured you had a 400ft tower though :)

Also, keep in mind that those 2 contacts were not typical for this location. Most of the stuff I have worked on 2m SSB has been from the Carolinas to Maine.

Being in DE or MT gives you an extra 40 dB.

Oh, stop exaggerating...... it's only 20dB. :neener:
