Hi all,
This April's RaDAR challenge will be my first.  I've fallen in love with QRP operation.  While testing a shorter/lighter wire to use with my 49:1 endfed transformer I made contact with a station in California from my front yard here in Western PA with about a 33 ft sloper antenna up about 15 feet.  I do have pretty good elevation for the region I live in.  I was using some really thin SOTA beams wire.  I about got my gear all put together and plan on hitting a trail I know.  I'll be using my Yaesu FT-817nd, love that little guy.  I've been learning CW and start the CW academy next month.  I'm trying to get more members from my club involved.  I've never been one to let the weather stop me, some come rain or shine I plan on being out there.

Cheers,
Tom - KC3TOM about 30 miles SW of Pittsburgh PA.

Re: 40m Delta Loop

I to like loops Tom =)    When I had a house I had a 80 meter horizontal loop about 10 meters off the ground fed with 20 meters of ladder line directly into the back of my manual tuner balanced line port =)   It worked GREAT on any band 10 to 80 meters  WARP bands where a bit to tune but worked =)   I built a 10 meter vertical delta loop for a new tech ( my first Delta Loop ) that worked and tuned by changing the feed point at the top by sliding down the feed point ( RG-58 ) a bit one side to a perfect tune all across the band =)   So I will have to make a 40 and 30 meter band Delta Loop for camping =)

The antenna is fed from the atu by open wire feeder and tunes up on all bands 80 thro 10. However I have delta loops available for 20m and 17m. These are deployed in upside down pyramid and are fed by a quarter wave of 75 ohm coax. Normal 50 ohm coax from the rig to the quarter wave.  The deltas can be horizontally or vertically polarised depending on how the are deployed. I normally use them vertically polarised as dx antennas.  They perform well in this mode. Without any salt water amplifier effect I have worked Antarctica on 17m. I have not tried them portable as yet.  But I will give them a go on the salt marsh this summer.  They should work well. Bit more work to deploy compared to an end fed half wave though.

John that looks like a great antenna to use =)   I have seen in the past Greg using one and I may give it a try as well =)    Hmmm .... a 30 foot push-up pole now with tent rain-fly spreaders =)

Finally got some mild weather in southern Ontario today so I put up an antenna I've been waiting to try out. It is a vertically polarized Delta loop for 40m. It uses 137ft of wire supported on a 30ft pole at the peak with the low, horizontal section just 4ft above ground. EZNEC modeling showed promising expectations so I was excited to test it outside as a possible RaDAR antenna.

I fired off some CW CQs at 5 watts using my Hendricks PFR3 radio and received an immediate spot on RBN from a station in Wisconsin 400 miles away. My signal was reported at a very strong 21dB so this antenna may be doing its job! Unfortunately I didn't get any QSOs but that has become all too common the way the bands have been lately.

Now I'm looking forward to a new RaDAR operating season with some new antenna designs. Hope to catch you all on the bands this summer.

Bruce check out the YouTube videos of the RaDAR group has done over the years on their outings =)   Wires and Mini-loops are used by many here as to keep a lite weight and small pack out =)    Check out Eddies blog and Greg's blogs as others =)   Each has a different answer and work for them =)    I have yet to make a mini loop antenna and usually do wire dipoles, long wire and a vertical mounted on a camera tripod =)

New to this group. Have not yet operated portable but I am considering a backpack station. I have watched some You Tube videos and have an idea on the equipment (plan FT981, Draws Workstation, LiFePo4 batteries) but I don’t know what will work for an antenna. Maybe we could have a section on what has worked well for other)

Thanks for the interesting group. 73, Bruce K8CJM Dayton, Ohio

Glad to see you are interested in RaDAR; Mark and welcome to the group =)   You will see people from all over the world as members here and we all share the same fun of using our Ham radio outdoors or anywhere =)   Sounds like you have done the /MM before on your boat =)   RaDAR is a way of perfecting you gear and antennas for portable deployment at any time or anywhere =)   The most important thing is have fun outdoors and share your adventures =)

Hi Everyone, 
I am Mark, M0IAX. I heard about radar initially from Julian OH8STN when he was taking part in one of your challenges last year. And I found the group thanks to a post from Pat N5VMO in the JS8Call group.

This group and challenge sound quite interesting and I look forward to taking part at some point, I have a few portable/mobile station options which Im hoping to have the chance to use more often when it stops raining :-)

I'm going to be putting together a better antenna system to use Maritime Mobile in,my RIB as I really enjoy the challenge of operating from a small boat and have had success in the past but I know I can do better.

Hi Tom
Thank you making contact and encouragement. Over the last decade HF ops for me have largely been away from home, either on holiday with my caravan or driving to QRM free locations. I started taking an real interest in /PM working some years ago after meeting with a very prolific YL /P operator, also known to you. Many informative Youtube videos have since been viewed, some yours, and books consulted, including military field op guides and the Pedestrian Mobile Handbook. I have since joined HFpack, RaDAR and VMARS. Looking forward to sharing a QSO with you.

Hello Norman and looks like you found Tom to help you out =)    Looking forward to working you at some time in the future =)   Welcome to the group share your adventures along the way =)   73 de N5VMO Pat

Re: Introduction

Hi Norman.  Good to see you are going to give pedestrian mobile a go.  You will be amazed at the contacts you will make from the sea wall.  With reasonable HF conditions you should be able to work good DX from your 703+ with a vertical fastened to your back pack plus a dragged counterpoise.  Back in 2003 I tested the 703+ as a pedestrian mobile rig, walking along the sea wall on the east side of the Colne Estuary , about 40 miles away from Canvey.  I was surprised to have  VK5HK come back to my CQ.  The report of those field tests is in the October 2003 Radcom.

Good luck with your /PM dxpeditions.  We should be able to have a /PM to /PM QSO - sea wall to sea wall! Hardly DX, and probably ground wave propagation,  but still, /PM to /PM is surprisingly satisfying.

Hi All

Since HF QRM levels are so high at my home QTH I resorted to /P working some years ago. Last year a 10 watt IC703 Plus, LDG AATU and LiPo battery were successfully mounted on a lightweight military backpack carrier for Pedestrian Mobile working. An ex-military Clansman PRC320, with 30 watts output, was also acquired and months passed while the various accessories, required to make it a fully working /PM, were assembled. Repairs have been made and modifications are currently underway to adapt it for easier amateur operation. My home QTH is Canvey Island which is surrounded by tidal mudflats, with seawall paths giving an excellent take-off.  More at https://www.qrz.com/db/m0fzw. Looking forward to working, meeting and hearing from fellow RaDAR Members.

Great pics Pat..........I'm experimenting with JS8CALL at the moment, I seem to be picking stations up ok but no one can hear me ha ha ha, very confusing.

The IC-7200 setting ( for the moment ) in the passenger seat =)
Using the single USB printer cable connection .... east setup =)

Then the old school keyboard and mouse ( yes I do have a very small BT BK / pad =)
Just did not use it this time ..... maybe when it is a more finished installation in the truck =)

Hope you enjoyed the pictures =)  de N5VMO Pat
