Cibola NWR 1

Curt writes: In DM23, I like to operate on BLM land just east of Cibola National Wildlife Refuge, . Easy access for any vehicle, flat and clear view of the horizon. I think it's about a half mile from the two-lane highway, not much traffic at all, so the acoustic noise was hardly noticeable. You can driver further east on the dirt road (it was in good shape) and find slightly higher spots, too.

I used to enjoy activating DM23 out of Kofa NWR, especially the cabin on the NE corner. But the Refuge management changed recently, and last year they denied an SUP application for any radio antennas. It seemed like a very narrow interpretation of their mission and policies, but so be it.

Don't go here, it's gated off.

This is an ideal example of a long slow drive to a perfect-looking-from-a-distance site. It's an activation location with buzz-kill gates. We only mention it to save you a trip. There is not much worse than having to turn around a 19.5’ vehicle on a 12’ wide road. The Chuckwalla Mountains Wilderness Area might have a good hilltop but this isn't it.

DM23pl is much easier to get to than the deep-wilderness spot at DM23mj.

We camped on site and setup the station on the night prior to the activation. We were located on a small hill giving us a nice horizon from North to South looking East. The site is about 150’ above agricultural fields giving a nice drop-off.

If you are activating grids on vacation, as we did, you should continue west on the Bradshaw trail to our deep-wilderness spot at DM23mj and the Hauser Geode beds. Note the Bradshaw Trail borders a US Navy bombing area.

Driving directions: This spot is located very near the town of Palo Verde CA at the beginning of the Historic Bradshaw Trail.

Restrictions: 4x4 vehicle is suggested.

This is a semi-wilderness spot in rare grid square DM23 located alongside the Historic Bradshaw Trail.

I would not suggest this remote location for a quick contest rover site but it is a good vacation/explorer/activator/meteor-shower-viewing location. There is great sightseeing and even geode hunting in the area, a "desert rat heaven".

This area is BLM land, you can camp almost anywhere and the Wiley’s Well campground is not far away from our activation site (South of Hwy 10). See Wiley's Well Campground | Bureau of Land Management ( .

We setup on a small hill giving us a nice horizon in many directions.

Black Mountain Road, off Ogilby Road, runs along a high ridge about 130 miles east of San Diego. It's an unpaved road in very poor condition that runs to the KECY-TV tower.

This is a large turnout and great place to park along Black Mountain Road high on the ridge.

Don't try to drive up to the very top - it has no additional benefit. This parking area is just a little bit lower and far from all the radio transmitter, and you have nice two row of hooks to secure antennas (there used to be something) and a portable toilet close by.

This is all BLM land, so no problem, the main mountain take only a small portion of clear visibility to SSE, but you can drive over the hill and setup on the other side should this be critical to your needs. This place turned to be noise free, with only some noise coming from El Centro and Desert Cities (Palm Springs etc.), but this is not a big deal, any station from these locations will be pretty close because then there is a water.

You will not feel completely alone there, there are always some technicians coming up the hill. The place would be hell hot in summer, that's for sure, but driving RV there could turn to be a very risky business.

Driving directions:

Approach from CA 78 and Black Mountain road you would notice place from far because there are countless number of radio towers - surely not the best place to operate from in DM23.

The road has two parts, the first unpaved which takes you through flats to wash, easily drive-able even in sport car, and the second half, paved road, with potholes 2 feet deep, which require 4WD and high clearance, it is total 5 mph hell.


Setup on top of the mountain is impractical - tons of radio equipment, high voltage lines etc., but before reaching the top, there is a small place to the left where used to be some equipment. You need a good tires and clearance to get there, but once there, you can find old attachment cables - part right in the middle and you have no issue to secure your antenna.
