Discrete Freq Canadian Air Force

[wheelerg]

Here in Trenton i here C-130's departing the base for local training in the area and they advise the tower they are "switching discrete" i assume that is a freq for what they are doing, but has anyone had any luck learning what those freqs would be? they train in the are but unable to track them to exact area so unable to use clsoe call function......

The only thing i hear from Trenton is on 268.000 Mostly planes calling in when they will land and any services or unloading needed.

Try looking between 136MHz and 144MHz.

Will do , thanks

When searching 138 to 144 don't forget to switch your radio to AM. Also they can go right up to 174 Mhz on 50 mhz stepping.

Ummm that makes zero sense. The RCAF most likely will NOT be above 144Mhz. Inter-plane will be AM but will probably be on 25KHz steps not 50MHz steps...

Any reason why he wouldn't search the UHF Milair band?

I would think use of the 138-144Mhz band in Ontario would be highly unlikely given the number of public safety agencies in that band.

The chance of interfering with and being interfered with are just too high. It's not the same as the US where I believe the military has exclusive use of that band.

While I agree that using this portion of the band there is the possibiltiy of interference is suspect it on VHF rather than UHF as he has said he has not found anything. Also, albeit Alberta, 4Wing uses VHF for inter-plane during training, it can not hurt to look between the top of VHF air-band and the bottom of the VHF ham band.

He said he hasn't been able to use the Close Call function. He hasn't said anything about actually searching the Milair band.

I havent heard them switch discrete since posting this, i will be searching milair when i hear it again but unsure when that will come, they usually go north of me somewhere so i will hop in the truck and drive north a bit....will advise when it happens and what my results......

Yes, my correction, 25 or 50 khz spacing. Why do you think that the RCAF would not use 138 to 144 or 174 mhz?

I would be VERY suprised to see an inter-plane frequency on Vhf-hi above 144Mhz or below 174MHz. I do not think I have ever heard of an inter-plane frequency in Canada above 144Mhz or below 174Mhz. 200-400Mhz sure.

I believe that one would have to live near a military training base to know if they use any other band other than UHF 220 to 380 Mhz and VHF 118 to 136 Mhz. Where I live you are lucky if you hear one Canadian military plane communication in a year so I would have no idea if they are capable of using 138 to 144 Mhz

Wheelerg who started this thread and who lives in Trenton and by the sounds of things is on top of what the RCAF use for UHF comms, was asking a question. I was merely pointing out the 138 to 144 or higher as a possibility as they are used in my neck of the woods by the USNG.

Being as all military planes are made by the same manufacturers I would only assume that they are all outfited with the same communication system. And as the RCAF work in joint military theaters with the USAF I would only think that they would have compatible communications systems.
