Folders, Files and Photos Ownership
2
A note about Photos Ownership: Whoever uploads photos becomes the owner of those items even though he/she may have never actually had anything to do with their creation and original posting. For the original owner to regain control over the items here is my suggestion - Contact the existing photo folder owner or photo owner and ask for ownership to be transferred to you as the original owner. A note about Files Ownership: Whoever uploads folders or files becomes the owner of those items even though he/she may have never actually had anything to do with their creation and original posting. For the Original owner to regain control over the items here is my suggestion - 1 - Create a new folder with the same name but add an asterisk (*) at the end of the folder or files name. For example an existing 6146 folder would have a 6146* folder next to it (if sorting is by Name). 2 - Copy the 6146 folder files back onto your computer. 3 - Load the 6146* folder with the files. Change the comments section as required. 4 - Ask the existing folder owner, group owner or a moderator to delete the original 6146 folder. 5 - After the 6146 folder has been deleted you can delete the * at the end of the name. 73 Roger VE7LB

Decal / Fascia Transfer Number / Letter Sticker Kit
Hi All, I have recently got my hands on one of these and would like to make it look pretty again and it has not been looked after that well. Its all good from a functional point of view but some of the lettering on the front fascia has been rubbed off and there are a few scratches around some of the knobs. I was wondering if anyone is doing a front fascia Transfer/Sticker kit that would give my set a refreshed look? Or, if anyone has any ideas of how I can achieve the same (or close) by means of a different process, then please share. Thanks in advance guys.

Beginning a FRG-7 restoration
5
Hello FRG-7 friends I have purchased a relatively well preserved FRG-7 from a friend. I owned one as a young SWL and used it to learn CW by copying maritime CW broadcasts on HF. I wonder if there are recommendations for a general restoration strategy. My FRG-7 is working quite well. I note the locking is perhaps a bit difficult to adjust in certain ranges. I am aware of the need to check/replace electrolytic capacitors and I have also seen resistors losing their nominal resistance due to ageing effects. So, I am keen on any "must-do" restoration actions and also "don't do" ones. I can imagine that some fine-tuning may perhaps be necessary. Perhaps there are also some often encountered faults in these old receivers. I bought my unit in 1977 if my memory is correct. I understand there is perhaps no separate service manual for the FRG-7. I recall seeing a "voltage chart" which may be the first thing to check. Thanks in advance for any comments, advice and information. 73 Dieter

BBC Short Wave Schedule
2
As an update to my earlier recommendations for listening to BBC World Service transmissions from Wooferton and external relay stations, I see that the Malaysia and Madagascar tx are no longer used. Vatican City and Oman have been added as relays. The current schedule can be seen at Global Short Wave Frequencies, and follow the links for more details. This page is updated seasonally. - Julian

FRG-7 Mechanical adjustment
8
Good day all. Question, how does the preselect drive clutch work please, has anyone had to adjust it. I have some backlash that seems to be within the clutch mechanism, the output shaft to the toothed drive for drum and on to the VC couplers is good. Interested if anyone has stripped the clutch before. Br. John.

Good day All. My Ebay lucky-dip FRG7 has arrived, and its what I hoped it would be, see pics below. There are a few things that Im struggling to identify, so if anyone has any input, that would be great, thank you. The serial number has extra digits, so if anyone recognises the number, please shout up. Serial number: 17 8M 240615 The PCB marked DL6 SW 004 is power from the DC rail, it 'seems' to have an SO239 on one side and a BNC on the other side, no connection into the unit itself at all. SO239 SW2 is no longer connected to SW1 or BC. Does anyone know what this is please. The XTAL is 38.66667Mhz There is something that looks like an additional modulator marked astec, does anyone have any info on this please. At the moment, its powered up, white noise when AM is selected, the lock LED will go out above 15Mhz ish but wont go out below. Putting a TinySA outputting at 25Mhz with 100Khz AM-mod near the antenna plugs induces the signal at 25Mhz and is auditable. That's about as far as I've got so far. Br John.

Good day All. I have a TinySA that have been using as an RF sig gen and a Zeewiie DSO1151g scope that 'should' run past 100Mhz, well lets just say 30Mhz is about its limit, this means I'm unable to look at signals in RF range. My question, attached are sample alignment procedures. Given that I dont have a fit-for-purpose scope (have three scope probes) but do have a TinySA and a NanoVNA (on the way) how should I then perform the alignements that require use of a scope, so what modifications do I make to testing and how should I review the results. Scopes, Im happy with using. SA and VNA interpretation, I'm not familiar with and no option to buy a higher bandwidth scope. Thank you. Br John.

Hello I've just joined this group and have a mint FRG-7...it came with its box and other bits. A friend gave me an old digital display unit which turns out to be a Timestep Electronics DFC-7 from 1981. It uses an OKI MSM5525RS LSI chip and a couple of others, one being an unmarked round can. Does anyone, by any chance, have some information on the kit please? Thanks Simon, M5POO, UK

Digital Display for FRG-7 - image resolution
Hi All, It seems that loading an image to messages reduces it's resolution :-( So I've put various images etc into files/DFC-7; resolution is 1600x1200 vs 1024x768. Something to remember for the future. Steve

Hello, I collected a FRG-7 yesterday. I thought it was in better shape and probably overpaid for it (EUR100). The overall aesthetic condition can be improved: It's painted in black. The power switch cover is missing. And the light dim cover and shafts are missing. the rubber feet, from bottom and side are missing. The carrying handle is missing. The rear lugs to keep the power cord are missing. I think all this can be improved. When switching on I can't tune anything, although the previous owner sent me a video of it working fine, so I guess I have not been lucky yet. There is something under the power capacitors, I'm not sure if this is because they are leaking. Also, some pads seem to be missing in the PCBs (not sure if this is a concern or not). I think everything is fixable. I appreciate any help or hints you can provide. Regards, Miguel

New FRG7 display from Marcel
9
Today the package arrived, awesome job by the postal system and our overworked customs. They are overworked because of our greedy government wanting all kinds of taxes from anything crossing our shores. The kit is of very good quality, and is very compact, well packaged and thought out. Marcel has done a very good job with this, I hope many take the opportunity to buy one, that helps creators continue to create niche products that big companies would not bother with. Tomorrow I hope to get time to install it into my FRG7, that can only happen if its raining, Im told the lawns need mowing............

Hi, In a previous post, I've announced that I was making a new kit for a digital readout with also a MHz indication. Now I've assembled the first PCB's and they function well. For an impression, look at https://www.youtube.com/watch?v=7iuP9ElnuoQ @Pentagrid, concerning your remarks about the RACAL RA-17. I'm in the lucky position to own one now. I'm busy, finding the right points for the signals and the power supply. The kit will probably replace the S-meter. For anyone who is interested, please contact me. Best regards, Marcel de PA8MA

Hi, I have my FRG-7 for sale. It is an early version without the "fine tune" control. It is in good condition for its age an works well. I am looking for offers near ?150 and it will need to be collected from RG31 area of Reading, Berkshire UK. Comes completed with original manual and circuit diagram.

Hello, I'm working on a new version of the digital readout. Does anyone know which font has been used for the dial in the FRG-7? Regards, Marcel de PA8MA

Greetings, I was given a FRG-7 by a friend. No clue as to the history of this radio. After cleaning all the rotary switches and volume pot I was only able to receive some local AM broadcast as the zero blob on the MHZ dial is the only spot on the MHZ dial where the lock light would go out. Tuning up through the entire MHZ range the lock stays on. In reading many posts here it was mentioned to slightly tweak VR102 to get the lock to work properly but no joy. So I'm at the point of deciding to try a quick alignment as described in the link below or hopefully someone here can suggest other items to check. https://worldradiohistory.com/UK/Short-Wave-UK/80s/SWM-1981-10.pdf Thanks in advance Brian / N6RZR

has anyone added digital readout to their FRG-7 this year ?
|

The FRG7 has around 12 turns of the tuning knob to cover a 1 meg band segment, pretty fast, requiring the finesse of safe crackers hands to tune in that ssb station, especially when the machine hs been fitted with narrow filters. Here is a very simple mod to slow that tuning speed to 75 turns band end to end. Remove the central plastic tuning dial from the kilocycle tuning capacitor, held on by one central nut, careful maneuvering under the S meter will see it free. Remove the three wires from this capacitor, remove the main tuning knob and carefully lift it out. Buy a ball reduction drive, these can be got almost anywhere, and eye up the space available after removing the front facia plate. Two 2.5 mm holes are drilled into the front chassis to mount the added ball drive in line with the existing tuning shaft. The existing tuning shaft will need shortening, use a hacksaw. Measure carefully. The radio can now be reassembled. The kilocycle tuning capacitor can now be slid back into the existing cavity another 15mm or so, and new mounting holes drilled to reattach it to the chassis. Reconnect the three wires to the tuning capacitor. The dial drum is now too small. I found a plastic jar lid the right diameter and drilled through the center to mount it to the shaft. Masking tape around the edge can be used to mark the 100 and 10 kc increments accurately as the radio is tuned, then this is transferred to a drawing program to make A professional looking dial..... Im still getting round doing that part..... Tuning is now so much easier, and the fine tune is no longer needed.. Originally, the kilocycle tuning is mounted forward toward the front panel as here. . .... After the mod, it is mounted toward the rear, you can see the added ball drive on the front panel...

Newly acquired FRG7 Loop light stuck on/loop not locking
7
Hello Everyone, I just acquired a broken FRG-7. I bought it untested for a decent price. After it arrived I tested it and confirmed my suspicions that the unit was not functioning. It appeared to lock correctly, tuning the MHZ dial the lock light functioned correctly but there was no readout on the S meter, and peaking with the preselect did nothing. I opened it up and found the previous owner had butchered the RF board, attempting to replace the front end transistor trying to swap it for an NTE 454. An attempt was made to solder the leads of the 454 to the old leads of the old front end transistor, the previous owner trying to use what I assume was plumbing solder. I removed all the butchery and hooked the NTE 454 up correctly. The receiver started to work immediately, and I was able to tune and peak on all bands. It was on for a few minutes while I tuned around the bands early in the day. I was able to get the BBC and several time signals. Turning the unit off and coming back to it a few hours later the lock light was stuck on, the receiver completely deaf in the front end. The lock light would only turn off when setting the MHZ dial to the lowest frequency. I read the manual, on this issue and took note of where VR102 was set, ans rotated it around a few times. I also used contact cleaner on all the switches, power switch, band switch, mode and VR102, still nothing. Lock light is stuck on. I turned it off and turned it back on and BOOM! It's working again! I let the unit run for 4 hours listening to all sorts of shortwave programs. Switching After 4 hours I turned the unit off and then immediately back on and the lock light is stuck again. Anyone have any idea what could be causing this behavior? The unit once working works flawlessly for hours, but it will then refuse to work at random, requiring random amounts of turning off and on again? I did read the PSU and its outputting high at 15.9 volts. Could the electrolytics in the PSU and AF board be causing power issues causing the receiver not to lock? Let me know what you think
