Wormald HF105

not much that is helpful actually

Geoff,

I tried a google search which turned up nothing useful. Have since phoned a couple of WA based HF servicers/dealers both of whom advised that Wormald went out of the HF business about 20 yrs ago so the unit is probably between 20-26 years old. Not a problem from a hf point of veiw because there haven't been any real advances in the technology over the years. One company said they thought the Wormalds were actually a rebadged Barrett, the other said they thought it was a Kimberely which was the hf company that Wormald originally bought out. So still a bit confused there.

Thanks for that info Gerry. It makes sense as the seller rang a few moments ago with more info and said it had Perth Communications on the unit as well as a service certificate from Outback Comms which is who he bought it off last year. Now I've got a list of frequencies from him I'm trying to find out what they are. Also the frequencies in the unit don't seem to match the ones on the whip aerial. Should they? I'm a complete HF novice in case you haven't already figured that out ;-).

Melissa,
the frequencies on the antenna must match those in the radio if you are to transmit on that frequency. There is a small variance allowable; eg, an antenna tap marked at say 5300khz will operate with tx's from about 5250-5350khz satisfactorily. Adding or changing frequency taps can be done, but is expensive. Similarly, adding channels to the radio can be expensive, as a separate crystal has to be purchased for each channel and the radio aligned.
Check out http://www.vks737.on.net/ for the 4wd net frequencies, similarly check out http://www.flyingdoctor.net/hfradio.htm for RFDS frequencies. Bear in mind that the 4wd net frequencies are probably the most useful for a traveller, 8022khz will probably do most of what you want, providing excellent day-time coverage from their range of bases across Aust.
If an antenna is provided, make sure that includes the spring base, as these also are not cheap.

Hi Steve,

Just got a bit more info from the seller. The aerial is a whip type with 8 holes (or are these what you refer to as taps?). I'm a complete HF novice so although the seller gave me the 8 frequencies that were listed beside each tap(?) I don't know what these are or when you should change over. Also, these frequencies don't correspond with the 11 frequencies in the unit itself. Should they??? If not, does these mean the aerial and unit aren't tuned? Based on what I've learned today we should steer clear of it if this is the case.

goodday melissa
just read your final post before typing this
also have a look on ebay bought my old codan set about $700 or look up some of the radio places on the net including vks 737 as most have 2nd hand sets for sale

Hi Bob,

Might be in WA but would still be willing to talk turkey ;-) re the Codan. My family is in Vic so perhaps I could arrange something. I'll be over later in the year myself. I've just member messaged you my email address. Like to hear from if you're interested.

for future reference the plugs are taps and should have frequencies or numbers by each tap. They should corrospond with the channel frequencies eg channel 1 is 6990 to use channel 1 you would push channel one on the hf then jump out and plug the wire into the ariel to the frequency or channel number that corrosponds. They are a good option if you dont use heaps of channels coz they are cheap (compared to autotune) and can be pulled off in seconds for bushwork
