11.275 mHz has nice music . coming in strong
my intent is to get this set up and working .
Citizen Band 11 meter covering the southern entrance to the + Land between the Lakes +
if i can get it up send a runner into the woods with a  1 watt  / 4 watt unit and test range . 
or someone in a car .. 4 watt . .. more with a heater . test local range .

and when the skip rolls   post up on the 11 meter section  , sending signal ,..

however . no  radio reception report .

https://www.amazon.com/Galaxy-DX-959-Channel-Mobile-Frequency-Counter/dp/B00415KISO
looks like a good set ..lots dials . set all about 1/3 , i put a D104 power mic on it  https://www.amazon.com/Astatic-302-10005-D104M6B-Amplified-Microphone/dp/B000KEY7MS
10:40 Z  11.725  mHz.. rock and rolling

Nice set of response .tyvm good input. think i am hearing Melbourne 11.275 25 m .. just now. kiwi
DX-959 +truck stop special+ 11 m + hour of bench time the tested and tweaked .. variable RF out put 2-8 ,clean signal i hope,  RM Italy KL 203-p 100w  . 10 meter 40W export units were readily available .
Sirio 5/8 wave  ground plane  affixed to a 1/2 wave aluminum pole . 75 " cable > astatic PDC2 swr and power it says>KL-203P  23dB preamp rx ,, 100 w tx  am more so in the SSB . >DX-958 ..
set the dials about 1/3 looking for contact, adjust as required .
this is not to say i have not gone full up..
blew a 4 amp fuse to the 203-p
hard wired it .
blew out the 10 amp/12 surge power supply .. oops.
monday  bigger unit arrives.
thing should be putting a signal out.
QRP well  a'int qrp local if it is transmitting i am blowing there socks off.. local i would be big ears looking for QRP
best i can tell i am going to have to get another set to get a good radio check[
i have another antenna i can deploy ..wire  dipole with a heavy duty balun .. throw the cord high
when i go to high power with the new power supply i should really be in the zone.
i noticed on the transmitter when i enabled the kl 203 p the lights dimmed and the needle dropped ..

not a bad set .. i wish i could find another hobbyest of a hill about 35 miles down range .. get on the SSB and yodel a one another

i heard  the old crow just last weekend .. Saturday  near sundown  . he was faint .. .. skip was really rolling .. very strong and intelligible signal from the FLA panhandle ..little bit from Baltimore .. .. i just wonder . i was up and +blowing smoke+ prior ,, blew oot the fuze on the kl203p ,, skip rolled , thn it rained for 2 days .  i think it was a troposperic duct but i have been fooled before

so a bigger flex would be indicated , bnc and or PL 259 ..intention : range tests at var power out put & antenna assy.

FM 24-18, ARMY FIELD MANUAL: TACTICAL SINGLE-CHANNEL RADIO COMMUNICATIONS TECHNIQUES (30 SEPT 1987).
i examine the 1944 ver. and the 1965 ver
from the 1987 ver
the formula :
3-8. Antenna Length
To calculate the physical length of an antenna, use a correction of 0.95 for frequencies between 3.0 and 50.0 MHz. The
figures given below are for a half-wave antenna.
Length (meters) = 150 X 0.95 / Frequency in MHz
 = 142.5 / Frequency in MHz
Length (feet) = 492 X 0.95 / Frequency in Mhz
 = 468 / Frequency in MHz
.....
thus:for 27.185 a 1/4 wave wire would be 8.6 feet
examine figure 3-26,3-33,3-34
Fabricate a field expedient Bent Bamboo antenna  , 1/2 wave Dipole /Hertz vertical iaw 3-34

BUT: the transmission lines illustrated are +twisted pair+ so i have become confused  i need to go study 11-666 on transmission lines
help me.
would it not be +fun+ bent bamboo antenna 1/2 wave vertical .. test with 1 watt , test with 4 watt , test with 8 watt .test var distance .. throw a hundred into it .. watch for smoke being released from the parts and wires..
i think i am missing something . somekinda balancing thing electronically speaking .
i still do not know if my DX 959 transceiver is fully functional . RX really good , under the radio theory of antenna reciprocity should be transmitting , have a little 60 cycle hum which rf ground might help . xmit and the needles wave . swr with slight needle movement. turn on the heater[emergency power]  KL-203P and get quite the needle movement, swr 1.5 .just the transceiver is in technical violation if i can believe the bench test. i need to get the little midland set so as i will know more

 i try to operate iaw FM 24-18 CHAPTER 6 ELECTRONIC WARFARE 6-4. Signal Security.. key words SELDOM UP

i think i need a AN/PRC-70 Manpack get in some big trouble with that

i have been studying radio propagation  since my SWL receiver is apparently inop i have using the T2FD KiwiSDR link above. like it. my first night monitoring listened to hams chewing the fat and a station from down under[by the accents]
11 meters = cb .. if i obtained a Amateur Radio Technician License [entry level]would have to learn code or work 10 meter band voice and it is dead too. USA opened the CB's for DX work [but not to foreign countries] http://www.arrl.org/getting-your-technician-license
the principles of radio do not change measurably between 10-11 meters .
i have hopes of finding another +Hobbyist  on a Hill +in the local area .. and wait for solar cycle 25 to progress.
there are other elements to the hobby.
i still need help with this equipment.

all done. set by length was 600mm , set by +cheep+ meter reducd it to 500mm.the organic dx 959 swr meter never showed deflection, the pos astic pdc2 showed 1.5 on ch 40 no deflection ch1. after antenna shortening by 100mm ch 40 showed 1-2 increment [.3 per maybe ?] ch 19 showed 2 increment , ch 1 showed 3 increment . too old and tired to jerk around abt 0ne increment .pole and antenna is up set in acceptable condition , next task is to install a RF ground to the cable .   now i need a reception report. sure should be transmitting , new radio bench tested , new cable , new antenna , hooked up on a 18 foot pole 500 ft ASL  hills and hollers as they say here abouts.
it on the 3's Now . gonna go up and do Radio 333.. ch 3 am . but will do ch 33 USB vice 36 .. rule of 3's ch 33. .
last post on this string . well maybe i get a radio reception report will close this out.

never did get a signal in on the dx-302 , forget the splitter. doing my SWL using N3JLY link. works good. now listening to 6.925 mhz .. + im the one they call the 7nth son+
...
all equip recd . in good condition. paid f/ hr bench time all checked.. power out of the box stated tx 1-4 peak 12 , turned up tp tx 2-8 peak 30 .. thars enuf f/ a NV . In for a penny , in for a pound . connected KL 203P  wonder if it works. did a smoke test . all the wires and parts seemed to retain the smoke.
antenna tuned by measure results in SWR less than 1 ch 1  ,1 @ 27.185, 1.5 ch 40 . i intend to let it down and shorten length by 1/4 inch and test again
it is a chore for an old man , lucky its light 18 foot pole & 17 foot antenna old man can handle. would be nice on a chimney mount .
itis only on a 10 foot pole just now . in the next config abt 1/2 wave off the ground to the bottom of the antenna , 17 foot antenna .  5/8 wave . i think it should work. however  no reception rpts .. yet . RX seems good 27.185 + the road+ La Strada + Federico Fellini

Sorry no RX rpt  .
equip rpt
Italian GPE 5/8 wave ground plane 26.4-29 mhz tuneable recvd in good condition . Very Nice , what a nice stick . walmart special big stick and 100 foot cable for 100$ .
shipped from Calif. 2nd day and took a week or more. AIR to BNA.
even w/o cabling up  i highly rec. this item. so pleasing.
the only down check is the attachment of the nylon housing/bushing /fitting between the very nice extendable alumin. stick , [ some really tight tolerances observed]
the keepers on the bush are inadequate .  easy fix, holes located well and easy drilled needs 3 bolts & nuts washers , kinda long , NA here so i glued it up w/ E6000 face fit edges top and bottom . in addition glued/sealed the clear housing over the bottom loading coil.
24-72 hrs to cure, Ill try to get it hooked up to the dx-302 Domani [ it is an Italian Thing]
will the DX-302 just boom in with this like i think ? or not .. place your bets sigrpt domani.

i
inspecting again .. the OD and ID of the telescoping aluminum tubs is *perfect*    wonder what the alloy is.. ..
i have a deal for you..  aluminium alloy 6063 T-832
i ordered too soon  and missed out , the thing i got true length is 17 '  this things true length is nearly 24 foot..
hot deal at amazon   Sirio New Tornado , 5/8 wave and 50 foot of cable 110$ delivered .  last left . i need it.. i want it ..
thing will take  1KW  - 3KW bursts  .
light weight well fitted ..

check out this exposed bottom loading coil https://www.sirioantenne.it/en/products/hf/new-tornado

gosh if it so well made as its little brother i could rig this for field day.. easy .. need a team 3 to deploy.
wazzit Z code more to follow
..
im happy  do not need a kw on the base 11  M . they would come get me. , and little brother 5/8 wave has the cute basket on the Top.. its gotta do something [what another question unanswered] QRP
im bummed out now . brought the ant inside  and cabled it up  to the old dx-302  , abt 6 foot  stick >coax>pl259>receiver.in the house . nothing , i think my receiver is broke,  true no ground nuttin , but i have a fair high power BCB  MW AM on a tall tower pretty near , nothing  i turned the dials from bottom to top . . id put this old thing in the shop , if there was one. id ship it to a good shop for overhaul .
i trust whenever the 959 comes and it will be a different story , not to mention the hot box.
i have a old CB +Rat here+ wife bought at a truck stop wanted me to install . box says 40 channel TRC 520 w weather.. actual unit is a TRC-50 ... this thing is an artifact  realistic mini-23.. has a button on the front , 1-12 or 13-23.. a old double crystal ..
