If your ham radio career began in the 50s or 60s, the designation ARC-5 probably brings up the image of a compact WW II radio. They were everywhere on the surplus market and most hams of the time probably owned one or two. Originally designed by Aircraft Radio Corporation, there were three models, the Navy ATA, the Army Signal Corps. SCR-274N and the Joint Army Navy ( JAN ) ARC-5. The ATA and SCR-274N were about the same except for paint and labeling, while the ARC-5 was an upgraded model. A 1626 oscillator drove a pair of 1625s to about 85 watts input. They covered 2.1 to 9.1 mHz in segments of about 1 mHz. Compact, simple and available inexpensively on the surplus market, $5 to $10 would do it, made them the budget transmitter of choice for many hams. VHF aircraft models in the 150 mHz range, like the T-23 shown above, were also made. One version had motor driven, rotating drums containing four separate coil sets that allowed remote channel changing. Matching HF and VHF receivers were also on the surplus market.

While not a true home brew project, surplus gear modification for ham use employed much the same skill set as home-brew construction. If you have a military rig that you have modified for ham use, bring it out and fire it up. We are including military radios, that you personally modified, as eligible for this challenge.

The first day of the month 0000Z through the last day of the month 2400Z

Make the QSOs necessary to complete the requirements below using your home brew or kit gear. All General Challenge Rules apply in addition to the QSO requirements below.

Twenty five (25) QSOs must be made on at least two different bands and include QSOs from EITHER 6 different states OR 6 different DX entities. Once the US state or DX entity requirement has been met, the remaining QSOs used may be any mix of DX and US stations.

It is not necessary that the station worked be using any home brew gear or be QRP.

Your homebrew gear may be a rig, tuner, key, antenna or station accessory. In the spirit of homebrew, please make it something that you personally built or at least did a significant part of the work. Since we do have to draw a line somewhere on what qualifies as homebrew gear, modular kits (eg. the KX3) and items such as store bought antennas which only require cutting to length and connecting coax and end insulators, do not qualify as home brew gear for this challenge. Please check out your rig and see what it sounds like on the air. Remember chirps, yoops and drifting around a few kHz during each over are no longer as accepted as they were in the 60s !

A certificate and Participation Point go to everyone who meets the 25 QSO, two bands and 6 different states OR 6 different DX entities requirements, and reports their results before the deadline.

A Participation Point goes to everyone who meets EITHER the 25 QSO, but not both the bands and states or DX entities requirements OR makes at least 10 QSOs and meets the QSO requirements for both bands and states or DX entities , and reports their results before the deadline.

A choice of an item made by master woodworker Gregg WB8LZG as shown on our prizes page here goes to someone selected via a random drawing from all who participate and submit a report for this month's challenge. A person can only win once, then they become ineligible for future drawings.

For a certificate, submit a statement that you completed the required 25 QSOs and that you met the QSO requirements for both bands and states or DX entities.

For only a participation point, submit a statement that you met EITHER the 25 QSO, but not both the band and states or DX entities requirement OR made at least 10 QSOs and met the QSO requirements for both bands and states or DX entities.

Please send a soapbox comment and tell us what HB gear was part of your station for this challenge. If you think that your HB gear is a bit different ( everybody has seen a K1 or HW- 8 ) or is military surplus include a digital picture that we may post.

PA9CW: It was a vy nice challenge. With 5 days holiday it was easy to make 25 QSO's. 
Best DX was 2150 km with UA. I used QCX for 30 meter and KX1 for 40 and 20 meter. CU 
in next challenge. 73 Tonnie

WB40MM: Hi All!  This month's challenge was completed with a Heathkit HW-16 that I 
built in 1969 when I was 15 years old.  All 38 Qs were made using FT-243 crystals, 
a Speed-X straight key, and a homemade G5RV wire antenna.  Worked 26 states, PR, and 
Canada.  35W out to a wire antenna using crystals and a 50 year old radio - 
unbelievable!.  It was a blast.  Most of these were made during the Novice Rig Roundup, 
an annual event that has folks using equipment that was in the novice license era.  Lotsa 
fun.  For the full story of the HW-16, take a look at: 
and scroll down to "MY ORIGINAL 1971 NOVICE STATION - WN2TAW".  It's a pretty good story.  
I hope everyone had fun working this challenge.  I sure did!  72/73, Steve #5913.
