My brother does the mountain climbing ham shit this time of year - SOTA ( https://en.wikipedia.org/wiki/Summits_on_the_Air ). Packs in his antenna and gear and goes hiking in the Cascades during the summer.

Yeah the guys on the ham radio facebook page and poked a little fun at me and asked what frequency it resonated at.... insinuating its an antenna...
but in my testing so far has not revealed any adverse effects related to the frame being copper pipe... i mean there is only so many materials at my disposal when
i get the idea to come up with something completely custom for my specific uses. smile

Re: hacked my self together a portable Ham Radio station... /w MBA 11"

Speaking of ham radio i got my amplifier fired up last night too... i had to run 240v to the ham equipment...  that was interesting.  if anyone asks my install is temporary!!  :-)

2700 VDC on the plate!!! Wooo.... can't push her too much past 1kw though because my radio resets...  must be from the standing wave ratio being too much...  I need to pull down my OCF80 and put up a Normal 80 meter dipole me thinks in order to get the full 1.3 / 1.4 kw out of those glowing 572b tubes.

Re: hacked my self together a portable Ham Radio station... /w MBA 11"

if anyone ever wants to browse the ham bands you can for free (if interested) www.websdr.org
its a great resource you can use it for analog and digital receive... like PSK31 conversations for example using FLDIGI and listening on 7.070 (40m band)
7.076 for jt65 and jt9 you can use WSJT-X and WFAX real-time weather reports, using again FLDIGI.  my favorite SDR is in NJ.

just saying, you don't need to have 1000's of dollars worth of equipment and antennas is all.

I use it when I'm at the office.

Ah cool.  I'll take a look.  I've always been a little curious about Ham, but have never had time to look at the equipment.

Re: hacked my self together a portable Ham Radio station... /w MBA 11"

yeah man and like what dylan's brother is doing, getting out with a few watts is quite refreshing.
i'm personally a full legal kinda guy... (full legal is 1.5kw on transmit) but with the digital modes low power mixed with good to decent signal propagation bandconditions.com on the band, can still give you some really fantastic results.

The only thing is now that we're on the bottom end of the 11 year solar cycle, and its getting worse, conditions have not been all that great lately.

I have an old Halicrafters tube-based shortwave and a portable digital shortwave. That's the extent of my radio geekery. Japan in the morning and South America at night.
