Easy SOTA: Blue Mountain (W0C/SP-123)

Joyce K0JJW and I were preparing to drive back home from the mountains and began to consider what Summits On The Air (SOTA) peaks might be on the way and easy to access. I consulted with Steve WG0AT, who had a number of good suggestions but we ultimately decided on Blue Mountain (W0C/SP-123). This is an easy summit to get to and an easy summit to hike.

I found Carey’s (KX0R) trip report to be helpful, so I suggest reading that information. To get to Blue Mountain, just get on Blue Mountain Road (CR 61) heading south out of Lake George.  Looking at your Pike National Forest map (you do have a National Forest map, right?), you’ll see that this road passes by Blue Mountain on the east side and then turns west. Take forest service road FS 244 to the right (north), which takes you up to the west side of Blue Mountain.This road turns into easy 4WD (challenging 2WD with high clearance). We just kept going on FS 244 (ignoring the side roads) and parked at the very last turn, as shown on the map (38.93108N, 105.35597W). At this point, you can just take aim at the summit (40.33530N, 105.28100W) and hike your way up. Approaching the slope at an angle makes it not quite so steep.

 

For this activation, we took along gear for 2m, 70cm and 23cm, FM only. Basically, this amounts to a pile of HTs and a few compact antennas. All of our contacts were on 2m FM except I did work Paul W0RW on Wilkerson Pass using 1.2 GHz (23 cm). At an elevation of 9230 feet, this location does pretty well on VHF and higher, so we easily worked stations in Buena Vista (W0BV), Woodland Park (WA6TTY) and Como (KD0VHD). We also worked a hiker (Jim, KD0MRC) on the side of Mount Yale, about 50 miles away.

The photo on the left shows my portable 2m FM station: Yaesu FT-1DR handheld transceiver, 1/2-wave Flex antenna (Smiley Antenna), and the dismantled 3-element Yagi (Arrow Antenna). I recently started using the Smiley halfwave antenna because it flexes on the connector end, making it more resilient to on trail use.

 

In the photo to the left, I’ve got the yagi antenna assembled and I’m using it to make contacts. With a little practice, the Arrow antenna screws together quickly and provides some nice gain over the halfwave vertical (about 6 dB).

We had excellent weather today so that helped make for a fun day. If you are in the Lake George, CO area consider Blue Mountain for an easy and fun activation.

Bike Ride and DX from East Andover

Judy and I rode our bikes on the old Northern Rail trail this afternoon. The weather was stunning. I worked England, Greece, Germany and the 13 Colonies station in North Carolina.

We started out across from the East Andover post office and rode our bikes east toward Dyers Crossing. Soon we came to the picnic table at Sucker Brook. I tossed a 33 foot wire over a maple tree and set up the KX3 on 20 meters.

The antenna wasn’t great because it was going in several directions… sloping this way and that around branches. But it worked well enough for me to make a quick QSO with my old friend Tom G3HGE in England. He had some interference and gave me a 449.

K2J in North Carolina was really strong. This is one of the 13 Colonies special event stations. Down the band a bit SV1CQN was calling CQ from Greece. We also made a quick exchange.

I was about to pack up when I heard DL2CC in Germany just finishing up a QSO. Frank was very strong to me and gave me a 559. He sent that he hoped I was having fun QRP portable. I assured him that it was fantastic to be out.

On the way back, Judy reminded me that we’re almost half way through summer.

LHS Episode #193: All About AREDN

This is the 193rd episode of Linux in the Ham Shack. In this episode, your hosts discuss ARRL Field Day, JT65 and new modes like it, the wonder of 6m and the E Layer, the NSA, patent trolls, useful command line utilities and more. We also have a great interview with Joe Ayers, AE6XE, about AREDN, the Amateur Radio Emergency Data Network. This one runs a bit long, but we thought it was worth it.

MFJ / Timewave Noise Canceller Shootout

 
A previous blog described a series of tests that Mark, VA7MM, performed demonstrating the effectiveness of his newly acquired MFJ- 1026 Noise Canceller. 
He, along with Guy, VA7GI, recently had the opportunity to compare the performance of the MFJ against Guy's Timewave ANC-4.

I'll let Mark describe the results:

NoiseCancellerShootout 2017 Report:

Guy Immega, VA7GI, and Mark Mattila, VA7MM, undertook side by side comparative tests of Timewave ANC-4 and MFJ-1026 noise cancellation gear (photos attached) by listening to interference at VA7MM in the HF spectrum between 7 MHz and 14 MHz. The program Spectran was used with the receiver on AM to adjust each unit for best performance and observe the relative performance of each. A system of coaxial relays was used to switch instantaneously between the units (photos attached).



Findings:

For practical purposes Timewave’s ANC-4 and MFJ’s 1026 are equal performers for eliminating interference in the HF spectrum.


Our findings corroborate the earlier findings of VE7CA that are posted on his website.

Switching the units in and out of noise was previously assessed on 40m CW, broadcast and raw noise. Examples of these tests are in a previous blogspot.

Commentary:

- main antenna in the tests was a multiband dipole at 30m above the ground.

- noise sense antenna was a Cushcraft R7 vertical antenna located 20m away from the main antenna.

 - receiver was an Icom IC-746Pro.

 - both units tested have the same nulling capability.

- the preamp on the MFJ was found to be useful in certain instances for boosting the noise signal.

- in one test instance the Timewave unit produced intermod with AM broadcast leaking into the receiver when the noise gain was set near maximum.

- in instances where noise was coming from more than one direction, the filters could eliminate one noise source, or the other, but not both.

General Observations:

- the Timewave and MFJ filters have a learning curve to figure out how to quickly and precisely null out noise. A couple of evenings of tinkering was required to figure out how to use the unit with different noise sense antennas and different types of noise.

- the noise sense antenna is critical and must pick up a strong noise signal for the units to work effectively. In most instances for local interference at VA7MM the noise sense antenna is near the ground and vertically polarized and the main antenna is high above the ground and horizontally polarized.

- both noise amplitude and phase need to be alternately adjusted to attain a good null on the units.

- using Spectran or SDR with the receiver on AM helps in adjusting the units.

Next Steps:

- discussions are on combining the noise canceller with a small vertical plane receive loop on 160 or 80m. The idea is that the combination of the two could enable noise in two directions to be nulled. The receive loop would be pre-amplified. 

- having two noise cancellers in series was also discussed as a means of nulling noise from two directions. An issue with this approach is that more processing electronics are put ahead of the front end of the receiver and this introduces its own noise and may create intermodulation. 

- I like that the MFJ unit has gain controls for both the noise antenna and the main antenna. Other differences include MFJ providing both relay and RF sense T/R switching whereas the Timewave only has RF sense capability. The noise antenna connector on the MFJ is an SO-239which I find more practical than the RCA phono socket on the Timewave. As far as mechanical construction is concerned, the Timewave is more robustly built.


We’re open to any questions on these findings.
