Was the meeting recorded if so can you please put it up on YouTube?

Thank Gary vk2kyp

Hi All,
Is there an Index of all the subjects contained in the Gippstech Proceedings?

Thanks Gary vk2kyp

Hi Lou, looks good.
I have had trouble driving the FPV amplifiers similar to one you are using. I have read there is a 16dB pad on the amplifier input that can be reduced to 10 dB reducing the drive requirement.
Have you experienced this.

Hi Tim,
I have GARC panel Transverter running 300mw on 3.4 GHz when you are ready .
I also have a W1GHz Transverter running 3 watts that need to be package up.

I can get an amplifier ready to run more power if required

Hi, just to confirm polarisation for 2 metre liaison
Vertical or Horizontal?

Thanks Gary vk2kyp

Thanks Peter, looks like this is the right part.

Hi All,
The power amp in the 3.4 GHz panel consists of 2 x HMC327 mmics. The drive is split for each device using a 90 degree splitter and the recombined after being amplified.

My question the driver has the marking "A62" is it known what this device is?

Thank you

Hi All,
Has anyone swept and measured the loss of the Panel filters? Before and after modifications

Thank you Gary

Hi All,
I plan to bring my Panel down to Gippstech, I am travelling by car with Steve 2xde.

it is running low power about 250 mW due to one of the output FETS is faulty and I have disconnected it.

Is there any plans for other bands. I can bring down 1296 and 2400 MHz if there is interest.

Thanks Chas, I use a mini-tube cutter to cut or strip the small hardline. It doss a very good job but can leave a "burr" on the cut edge which makes it difficult to remove the outer sheaf.

Thanks 73

Hi Chas thank you for showing us your "Soup Can" feed.

I am currently also make a feed for 3.4 GHz.

How did you remove the inner Dilectric and conductor from the UT-085 coax.

Thank you

Hi All,
The next 3.4 GHz QSO Party is on Anzac Day 25th April, who in NSW is going to participate?
I have my panel working running low power ( about 250mW).

Any takers?

Hi All,
Can someone please bring some panels to the Wyong field day?
please message me
Thank you

HI all, My Panel was working very well until yesterday afternoon, Tx power output +30dBM and I could hear -120dBm. Now the board draws about 1.5 amps and now difference between TX and RX. I suspect short circuit PA MMIC's I used my version of Dave 2jds receive modification using a pipe cap filter be...

Hi All,
I should be operational, just putting the finishing touches on my panel.
I would like to confirm a NSW liaison frequency and if it is a repeater, what tone access will be required?

looking forward to a great day

Hi All,
I was considering an amplifier for the TR3500.
Has anyone tried a 30 watt amp with the TR3500 ? A sequencer and suitable TR switch will be required.

What are the power limitations of the existing Patch antenna?

73 Gary vk2kyp

Hi, OK at 10.368, getting close to cut-off
