Max 250mA with the lights on with normal volume.

Hi group, and thanks for having me! Anyone who can tell the current draw for a FRG-7, when using an external 12V PSU? I have a nice linear little PSU, but it's only capable of delivering 0,9 A

The filter board uses diode switching to prevent long signal lines. The diodes on the in/outs of each filter are either forward or reversed biased via a DC voltage to activate, the half rail voltage

Mike, et al, Thanks for the suggestions and pointing me to some of the mod files - I will definitely check them out.? This is now not as urgent as a couple of days ago as I am waiting delivery of a

I would love the schematics you mentioned. These seem like worthy mods! Thanks, Robert

Improving the FRG7 selectivity by replacing filters is problematic when going much beyond a 3-4 kC bandwidth and expecting improved SSB reception. The cause is the Yaesu? free running BFO is just not

radio west upgraded all their FRG-7 filters before shipping and you had the option of further upgrading of the filter including switchable filters

look in the files section for the file Gilfer frg-7 mod, that explains the only way to improve selectivity in the FRG-7 smaller sized filters (based on number of elements) will not require legs to

I am *NOT* and FRG-7 expert. I bought one and completely realligned it. Sensitivity is excellent, but it was designed as a general purpose shortwave receiver, not a communications radio. However, if

I have several murata filters that I have for sale that can significantly improve your selectivity and with a little extra work you can make a two filter system

Hi, Y'all!? Long time Frog owner but first post here.? I'm hoping the collective can help me put this radio into mainstream use in the shack. I have been trying to pair this up with a Heathkit

To start with, a complete alignment according to the service manual. Op zondag 16 juli 2023 om 01:22:59 CEST schreef Chris Rogers via groups.io <crvee8@...>: I have a

Thanks to everyone for their tips. I will do some more investigating and see how i go.

Hi Dayle, Thanks for your advice. I will give it a try and see how I go.

The fault lays in the Wadley loop section . You need to ascertain the Mhz VFO is working, this runs from 55 mHz to 85 mHz. Because your lock light goes out at the higher frequencies, this oscillator

Do you have the manual with the alignment instructions? You need that and a nanoVNA and tinySA or two. The 2nd is for use as a signal generator. Connect CH0 of the nanoVNA to the antenna input attach

Chirs you will likely get a hundred different answers. I had a FRG-7 that was deaf. It turned out to be coil L101. This is a large multi segmented coil. The problem was the ends of the coil are wire

I have a FRG-7 that has the following non working symptoms. The Mhz led can be tuned out on the upper shortwave bands only, and a few stations can be heard at very low volume. The Mhz led does not go

Buy an nanoVNA from a reputable dealer like R&L and follow the manual procedure. Twice. The circuits interact so the 2nd pass is to compensate for that. You're unlikely to see significant change on

I am beginning to think this radio is actually fine, it has been misaligned.? The VFO, "mHz tuning" should span from 55.5 to 84.5 mHz.? The first IF should be centered on 55 mHz, this can be checked
