Yaesu FT-891 HF Mobile Current Drain and life as a Portable operator


You can wait forever to have the Yaesu engineers design a replacement radio for the FT-817**. It turns out they were too busy working on the brilliant FT-891 radio that has become my replacement for the FT-817 (I am still keeping my 15 year old radio). Yaesu sold a ton of 817s, 857s, and 897s to many hams that used it for mobile and qrp activity.

Why the 891 you ask?

At $600 USD its a steal. The new DSP chips make it a wonder to behold and fix all the DSP issues the previous models had. Add in the speech compressor, scope watch and a sensitive receiver at that price and there is no question why they were sold out by christmas time pending another production run. Thanks to my friends at HRO in finding me a radio in time for my 6Y5 dxpedition.

Sure there is no built…

New FT-818 Yaesu is not really a New QRP rig its the same rig with a new Battery


Yaesu has released their new update to the FT-817 after over 20 years and it’s a boring update and may not be a big success as hoped to be.


Martin Lynch and Sons the largest UK stockist for Yaesu is accepting deposits for this $600 British pounds sterling ($1100 CAD)

The new FT-818 incorporates all the many basic and attractive features of the ever-popular FT-817ND while providing upgrades desired by many existing owners.

The FT-818 provides 6W of solid output power with external DC power source. The supplied Ni-MH battery pack (SBR-32MH) has been upgraded to now provide larger battery capacity – 9.6v/1900mAh. The FT-818 includes the build in TCXO-9 oscillator that gives the FT-818 fantastic frequency stability (+/-0.5ppm). 5Mhz band (WRC-15 frequency is also available on the new FT-818.

The FT-818 includes all the…

GO BOX Out in the Field


Getting out in the field and practising radio operations is always a lot of fun. This time I had a car battery and a big SLA as I wanted to also run 100 watts using the NVIS antenna as well as a vertical.

I was ecstatic working the special event Indianapolis 500 station on 40m  on the first try.

The site was ideal for radio work until York Regional Police showed up.

Based on the garbage I found while erecting the antenna farm I am not surprised they dropped by to a radio check.

The officer did not understand that during the Emcomm exercise we had comms into the York Region Public Safety liaison teams.

Once I explained what I was doing he went onto his next task of the day and I jumped back into 2m simplex while keeping an mic on 40m.

A Review Of FT8

On Feb 12 I decided to take a serious look at what operating with the FT8 mode was all about. I had the software configured, the equipment all ready to go, fired everything up, tuned up on 18.100, and started trying to make contacts and, well… In a short time I’d logged contacts with Southern […]

40M NVIS with the Chameleon CHA Hybrid Micro Antenna (MPAS)


Chameleon Antennas makes the brilliant MPAS system which is comprised of various components.

This lends itself to field, bush and portable operations very well for the active have radio operator that is on the go.

Its a 60 foot longwire and a whip element for two different configurations (many more ideas at their website in the documents section)

I like to operate this as a NVIS set up with the antenna about 5 feet off the ground on the 40m/60m band and its easy to get signal reports by checking into the numerous nets.

Running 10 watts calling CQ can be time consuming if the band is light as many hams dont bother with weaker signals (and many have poor antennas – if you cant hear em you cant work em)  anymore but running NVIS I can make good contacts within the regional zone easily.

If you dont have the…

HF Bands Characteristics


I was bored sitting by the Carousel waiting fro my luggage to show up and just crammed this up to give guidance to new operators what the bands are like

HF Bands Characteristics


  • Late evening and night is the best time.
  • Winter offer less lightning noise
  • Summertime noise levels make this band difficult


  • Evening/night early morning
  • Best in winter


  • Early evening through early morning
  • Fall through Spring

This band and 20M are sometimes the workhorse bands at night 40 m is open everywhere


  • Its like 40M m and like 20M
  • The in between band
  • CW and Digital modes only


  • Open somewhere 24 hours best fall through spring
  • This band can be very busy with lots of pure random and lots of signals a beam antenna can be very useful


  • The in between 20M and 15M band


  • Sunrise to new typically Europe and Africa…
