Very embarrassing

The bands were very dead for DXCC's so I turned the radio off and decided to just do some web surfing and that soon became same old same old. I then had a brain storm that it has been just way to long since I had a good old fashioned QSO. Most of my time has been hunting for counties that I need for my ARRL Jubilee award. This meant for the past few weeks and maybe a month or so I have been just working the CW key with "599 73 TU" and that's it. I turned the K3 on and it just happen to be on 14.060 and KM4CU was calling CQ. I came back to him and the QRP to QRP conversation began..........so I thought!! Tom's code was great from Florida........my code..... not so much. I was absolutely embarrassed. I kept messing up his call, I could not even get passed "nice to meet you" it was like my mind went BLANK I was not able to figure out what to say and how to translate it to code!!!  Tom was very fast to send his 73's to me (it was like I was an ugly date). Once again I just struggled with the ending and once done ( which seemed like for ever) Tom was just gone........it was like a Morse code blind date that just went south very fast.......very embarrassing!!!! Tom if you read this blog I am very sorry for the code train wreak. LESSON LEARNED

My first 24 hours on WSPR

My first beacon on 30 m, a free-running Ultimate QRSS kit (no GPS) has now been running for a full 24 hours using the Weak Signal Propagation Reporter (WSPR) mode. The figure comes from the WSPRnet page.

With an output power of about 150 mW to an 80 m horizontal loop it has not been possible to reach beyond Europe so far. Perhaps this will happen in the future with better conditions and/or with some more output power.

Along the Pemigewasset River

Today I road my bicycle along the Pemigewasset River. It was sparkling. I worked a mobile station in Montana and two QRP stations… one in North Carolina and the other in Ontario.

The old road runs along the river in the Army Corps of Engineers flood control property in Sanbornton. Today I rode about a mile north and stopped at a sunny spot right along the river. It was dazzling.

I threw a line over the branch of a tall pine tree and sat down along the bank. I ran 4 watts with the little HB-1B on 20 meters. To my west was the river, and to the east, a steep hillside that rises nearly 700 feet toward Knox Mountain. I was pretty sure any QSOs would not be coming from Europe and I was right. I heard NT7R mobile in Montana calling on the county hunters frequency and I made a quick contact. Then I went up to the QRP calling frequency and heard Steve W5QC calling CQ from North Carolina. We gave each other 559s. Steve was running an 817 at 2 watts with a telescoping antenna right on the back of the rig! Fantastic. He was camping in North Carolina. As soon as we finished, Gary VE3MPQ called me from Windsor, Ontario. He was very strong at 579 and he gave me a 579 too. Gary was also running an HB-1B at 4 watts. We chatted for more than five minutes with perfect copy both ways.

When I told Gary I was sitting by the edge of the river, he sent, “I’m jealous of your QTH.”

After operating for a bit more than 20 minutes, I headed south back down the road. It’s nice to have the camera to record these wonderful afternoons. But it doesn’t record the sound of crickets, or the touch of a cool breeze on my face as I peddle along the river. It doesn’t catch the smell of early fall or the nostalgia of the first fallen leaves along the trail.

How Much Does That Second Band Cost?

I encourage newly licensed radio amateurs to go ahead and get a dual-band FM rig…handheld, mobile or both. I think the additional cost of the dualbander with both 2 Meters (146 MHz) and 70 cm (440 MHz) is justified by having the ability to operate on the additional ham band. I have noticed that the price of the single-band 2 Meter mobiles are pretty low, less than $200… a real bargain in terms of technology. This made me wonder what the price premium for the second band (70 cm) really is.

I pulled all of these prices from the same major ham radio web site, trying to keep some consistency among the price of the various models. (I ignored specials and coupon pricing.) I looked at a basic 2 Meter FM rig and any comparable dual band models from the same manufacturer. I tried to stick to the basic transceivers and not include models that had advanced features such as D-STAR and APRS in them.

The data is captured in the table below. Note that I differentiated between a single receiver (one frequency at a time) dual-band radio and a two receiver dual-band radio, since the latter variety is much more expensive. I calculated a percent premium for each of the dual-band transceivers, calculated as the percent increase in price over the single-band radio from the same manufacturer. I think this is the most objective way to describe the extra cost of a dual-band radio.

TransceiverPriceBandsPercent Premium
Yaesu FT-2900R$1852M
Yaesu FT-7900R$3302M/70cm78%
Yaesu FT-8800R$4602M/70cm Dual Receiver149%
ICOM IC-2300H$2602M
ICOM IC-2820H$6702M/70cm Dual Receiver158%
Alinco DR-135T$1702M
Alinco DR-635T$3202M/70cm Dual Receiver88%
Kenwood TM-281A$1452M
Kenwood TM-V71A$3952M/70cm Dual Receiver172%

It is worth noting that only Yaesu and Alinco offer a single-receiver dual-band rig. These two radios are 78% and 88% more expensive than their single band counterparts (less than twice the cost). The two-receiver dual-band radios are consistently more expensive, with a price premium ranging from 149% to 172%. While these rigs are often described as having two radios in one, they are more than twice as expensive as a single-band radio.

Although I appreciate the extra utility of the two-receiver radios, it looks to me like the best value is with the single-receiver dual-band rigs.

What do you think?
