Ground plane for 2m and 70cm.

I thought of the same thing, but didn't do it. You get all the points for that one. Somewhere I saw something like this for sale, it was slightly smaller and targeted the IC-705.

While ICOM is the main rig of zillions of HAMs and the fact I have always been a Yaesu fan, this is not a jibe either. But for 1295.000 SRP I would think they could have included a built in antenna tuner. Come on! I can buy two Xiegu G90's and still have enough left over for lipo batteries for both of them. ICOM and Yaesu need to get it together both in what HAM users want and stop looking at just the die hard base of buyers if they want to compete down the road. That being said I think Elecraft is in a pretty good position and Yaesu has the engineers to totally redesign the 818/891 line with a tuner built in. One less thing to lug around and maybe a tipping point for those that want an all in one SOTA or POTA radio. Perhaps ICOM and Yaesu do not want to tick off their after market partners?

Which is better, an antenna cut/tuned for the band, or an antenna tuner for a not so cut/tuned antenna?
Sometimes, using an ATU is required. While it would be great to always have something resonant, it's not always possible or practical.

This is a trick question, right? A resonant antenna will generally have better RF performance than a non-resonant antenna that is brought into resonance by an antenna matching device. However, RF performance is not the only factor for a QRP antenna. A QRPer who backpacks into an operating position may not be able to transport and erect a resonant antenna. OTOH, if that same backpacker depends on a non-resonant antenna with tuner, then they have to consider the weight and bulk of a tuner.

That said, the word "tuner" appears in this thread over 30 times. I think we all get it. Some folks think this radio should include a tuner. Some folks don't see it as an issue. The fact that it doesn't include a tuner is well known. The fact that the radio is more expensive than the cheap, Chinese QRP HF radios is well known. I really think we should move on about the tuner issue.

Hello,

I was up at HRO Salem, NH on Tuesday and noticed they were shipping out IC-705 orders, but no stock on the website. The had the IC-705 box, backpack and accessories on display, but no actual radio out on display. I noticed tonight that IC-705 stock is starting to show up on the website!

They also have the backpack in stock.

FWIW that's already sold and no wonder.

I'm thinking this radio is going to be rather polarizing. Either love it or hate it, not much in between.

But, but, I can buy four Baofeng UV-5Rs for the price of one low end Yaesu hand held and have enough left over for several Baofeng batteries.

And you get what you pay for.

Hello,

Something interesting tonight. I saw a message on a Unification pager thread that Walgreens sells a Just Wireless Bluetooth Headset for cheap money, I thought I would try it, so I got one. I had no problem pairing it with the IC-705. If I press the "main button" twice, the IC-705 goes into transmit. If I press the "main button" once, it stops transmitting, Microphone quality did not seem that great.

I decided to retest my Sennheiser HD 4,50 BTNC headphones. This time I was able to go into transmit by pressing the Multifunction button two times. The radio goes back to receive by pressing the Multifunction button once and the headphones say "call ended". Looking at the manual the single press and the double press activate different functions. The transmit audio sounds better.

So it appears if a Bluetooth headset is designed to answer calls, then it might be able to be used to transmit using the two taps to transmit and one tap to receive method.

prcguy, where is your review of the IC 705? Being out in the desert, you should have had enough time to give of a review? Am having a field day using it for scanning HF. The water fall display helps so much identifying signals. Can see why the 8600 folks love there radios. But I really enjoy sitting on my recliner, not hooked up to a power unit being battery operated, and scanning the HF bands. The touch screen for options is awesome. May be a expensive receiver for me but worth every penny!

Didn't get much operating time, had too many antenna problems. My lay on the ground Eyring antenna was not working well and when I was collecting all the parts to go home I found a rodent had chewed off one of the wires so I only had about half the antenna available. Then my backup High Q screwdriver motor would not turn to tune the antenna . I did a lot of listening on the partial lay on the ground antenna and that was very nice, I didn't see any difference between the IC-7300 I had with me and the IC-705 on receive.

For power I was using a Thales 6.8AH MBITR battery with adapter to Anderson Power Pole then the Icom supplied power cable. One battery was good for several days of receiving.

A Comet CF-706 diplexer will work, or just use a switch.

That ELPA antenna is very interesting. I have not come across that before. I will have to suffer with a Chameleon loop in open terrain.

I've used the 150 watt Eyring with good success in the past and this time I had a 500 watt version for the first time. Its also the first time I didn't take an 80-10m EFWH or OCFD on the camping trip.

I think the low power is the 320A model I was searching for. The adjustable directivity of that type of antenna is interesting, as well as being on the ground or sort of on the ground depending on what is being done with it and where. I looked at the manual and was definitely curious about the different possible configurations depending on terrain as well as intentions/needs. I read chatter of building an ELPA, but the links were dead. Hmm...I should check the Internet Wayback Machine. I might get lucky. With only 10W out of the 705 and no need for a tuner, it would be interesting to see what could be done using an ELPA. I look forward to your next trip to the desert.

I honestly did wonder to myself why in the world "you" would not have taken an EFHW. I figured the lack of elevation for one or both ends was the issue in the desert. As to the motor, who could predict that. While I always carry that EFHW using the parts you sent, for desert sessions I would take the loop and a Buddipole. Setup both and when I get tired of fiddling with the loop, use the BP for some wide tune NVIS, or as a vertical with elevated counterpoise.

As for the OCFD, I am a big fan. Still, it is a bit much to rig up for one person along with all the gear it takes to raise it using a mast. Thus, my piqued interest in the ELPA which looks quick and painless.

I am surprised that Icom does not offer a manpack type vertical antenna with the 705. I have the Icom AH-703 HF vertical antenna with the two line counterpoise, but I mainly use it for RX and have never given it a chance on TX. Talk about a compromised antenna. The weather is nice and I should setup several of these QRP antennas and compare here in heavy RFI land in my backyard and again out in Nowhereville.

That sucks. Dam rodents. Will be waiting for your review. Am having a blast using mine. Still have allot to learn but so far so good.
