Icom 705 Survey Monkey Product Feedback and Improvement Lifecycle
We are months away before the awesome Icom 705 hits the North American shores for sale
There is demand for the Icom 705 Plus version (includes a Tuner) and a bigger BP-style battery pack
Here is the survey
Thanks for you help as I work with Icom to release the radio we wanted in the first place beyond a 7300/9700 mashup
I just threw a wire off the back deck with a balun and turned the radio on a there was K1M special event station to celebrate the landing on the moon
I worked him with 10 watts SSB on 20m no problem! and QSL was received
This radio offers 20 watts, SDR design and a built in tuner
I got my from Jerry Wagner at Connect Systems and you you call him to get one and mention my name he may give you a special discount
Icom can learn from Xiegu, if they can put a antenna tuner in a field radio then so can the Icom 705 Plus version
For immediate release:
Icom announced the new Icom 705 Field radio at ham Fair 2019
All Modes including DV and covers HF, 6m, 2m, 70 cm
The European model will include the 4m band
This will compete against the Yaesu FT-991/991a directly offering multiband performance in a single package.
Icom 7100 is now going to be officially discontinued and all inventory being cleared out to make room for this radio at retailers shelves
Its missing the built in tuner forcing users to add a AH-4 or LDG tuner to the go box
HF + 50MHz + 144MHz + 430MHz
SSB | CW | RTTY | AM | FM | DV
10W output power
Large color screen
Internal battery that can use batteries from the ID-51 handheld. Please note the belt clip will need to be removed
GPS & Bluetooth
Can be charged via USB port

The Hiram Percy Maxim Birthday Celebration gets under way on Saturday, August 31, and wraps up on Monday, September 8. The 9-day operating event commemorates the 150th anniversary of the birth of ARRL cofounder and first president Hiram Percy Maxim, W1AW (HPM) — born on September 2, 1869 — and is open to all radio amateurs. The objective is to work as many participating stations as possible. W1AW and all ARRL members will append “/150” to their call signs during this event (DX operators who are ARRL members may operate as <call sign>/150, if permitted by their country of license.) Stations will exchange a signal report and ARRL/RAC Section. A total of 84 multipliers are available. DX stations will send a signal report and “DX.” All Amateur Radio bands except 60, 30, 17, and 12 meters are available. Contacts may be made on CW, phone, and digital…

At Dayton Hamvention 2019, the CSI Group announced a special deal on the Xiegu G90. The G90 is the first model of the new Xiegu G-series and is from a Chinese manufacturer. It is a man pack style portable 20W HF 10-160 meters transceiver with handles. The G90 uses 24-bit digital SDR architecture. It also includes an internal automatic antenna tuner.
Why another QRP radio in your collection?
I wanted a radio that had enough HF power (20 watts) to run off a reasonably sized Bioenno battery (the 4.5 or 9A) to make up for bad band conditions. 20W is about an S unit down from a typical 80-100 watt base station so no penalty for field operating (5W would be another S unit). I have found the military man packs all run around 20 watts on HF and my practical experience shows it to be a great trade-off. I…

The Basics of NVIS
NVIS (pronounced “niviss”) is Near Vertical Incidence Skywave HF-SSB propagation for communications between 1.8 and around 9 Megahertz and is essential to anyone requiring reliable HF communication from 1 to 400 mile radius.
For practical communications plans and operations, NVIS functions between 1.8 and around 9 Megahertz. Frequencies above that range the signals penetrate the ionospheric layer instead of the desired reflection back to earth. NVIS requires the signals to bounce back.
A NVIS antenna is always horizontal. A vertical antenna can never be used, including mobiles. Mobile antennas are actually angled to be horizontal if you wish to operate in NVIS.
A NVIS antenna has omnidirectional radiation.A NVIS antenna is low to the ground. It should be deployed less than twenty feet above the ground.
A multi-frequency NVIS antenna requires an antenna tuner at the feedpoint of the antenna system.
If you use a dipole antenna with an automatic antenna tuner to operate…
