Anytone Smart CB for 10M

Small 11m/10m AM/FM mobile

Bought May 2023 from http://www.4x4cb.com/index.cfm - very helpful and friendly CB dealership - well recommended
User Guide : smart.pdf
User Guide : manual_anytone_smart_i_eng_cb.pdf

Modification

Modification to “Export Model” to provide 10m (and 12m) amateur bands and the 11m CB channels
Solder 2 jumper pads as per photo:

Resulting 14 bands can be selected:
- Power-on while holding A/F and cycling through with Mic UP and DN buttons
- Once selected : Power Off, Power On. Display briefly shows active band

Band	Channel 1	Channel 40	Comments
A	25.615	26.055	SS Low
B	26.065	26.505	S Low
C	26.515	26.955	Low
D	26.965	27.405	Mid / CEPT EU
E	27.415	27.855	High
F	27.865	28.305	S High / 10m
G	28.315	28.755	10m
H	28.765	29.205	10m
I	29.215	29.655	10m (29.600 = CH35 R)
J	29.665	30.105	10m +
†	25.165	25.605
L	24.715	25.155
N	24.890	24.990	21 Channels 12m Ham
U†	27.60125	27.99125	UK CB

All channels (except in Band N/12m) end in 5kHz. To drop to -5kHz (end in 0kHz) press/hold RFG. R is displayed.
- For 10m FM on Band I 29.600 is Channel 35 R
The bands follow the usual CB pattern, with 10kHz jumps, Alpha Channels, after 3, 7, 11, 15, 19. The Smart CB includes these as 3A, 7A, 11A, 15A and 19A.
All bands (except Band N 12m which only has 21 channels, and the UK CB band) follow the CB channel protocol of out of sequence channels 22, 23, 24, 25, 26 thus
- Band I (10m FM) with -5kHz R activated
  - Channel 22R : 29.470
  - Channel 23R : 29.500
  - Channel 24R : 29.480
  - Channel 25R : 29.490
  - Channel 26R : 29.510
- The Channels, in frequency order : …22,24,25,23,26…
To select Output Power:
- Press/hold RFG, PTT and Power On
  - Use Mic UP and DN to cycle through 3 power levels:
    - PL = 4W
    - Pn = 8W
    - PH = 15W
  - Once selected : Power Off, Power On
  - 15W might be overdoing it - in such a small package with limited heatsinking. 8W is probably the best option.

10m Channels

Assume R -5kHz is active

Also check with R inactive (freq. ends with 5kHz)

Update July 2022

I've modified the server/client code to create a single-radio AR7030 control program that gives access to IF filter, and reads s-meter etc.

New (July 2022) version of Tkinter GUI with S-Meter graph and IF filter Selection

CRT SS9900

Multi-Mode 10m/11m/12m

Background

I wanted a mobile 10m radio for use on 10m FM, and occasionally SSB, to try and re-capture the fun I had in the early days of being a ham (1983). Looking around I found a lot of choice of radios covering 12m and 10m amateur bands, and (of course) all the space in between containing the 11m/CB bands.

I bought a CRT9900 which seemed to offer the best versatility - it's more like a ham radio than a channelized CB.

It's hardly been used - I don't think I've ever had a QSO with it yet - so I now intend to make a concerted effort to get some use from it, and even looking at 11m when 10m is moribund.

Propagation conditions should be improving as Solar Cycle 25 peaks, and (writing this in early May 2023) the summer Sporadic-E season should also bring some inter-Europe propagation too.

p.s. I even have a CB callsign from the Charlie Tango group : “108 CT 2182” (108 = Scotland and I asked for 2182 as a nod to SSB marine radio)

SSB TX EQ

I'm not naturally a 'phone operator and avoid playing with audio settings as much as possible. I prefer simple “communications quality” audio when I use SSB. As the FT-891 is intended to be my “phone mode radio” and I've done some initial adjustments to try and achieve a clean, basic communications-quality setup.

From what I can work out, the “bandwidth” settings of the EQ refer to Q - the smaller the number the lower the Q and the wider the affected bandwidth. I'm aiming for gentle shaping of the voice band to cut the low-end boomy bass and lift the high end “articulation” so I've set a low-Q on each pole of the EQ filter. I've set both the non-Compression and the Compression EQ settings to the same values - I want the audio to sound the same with and without the processor. The Mic's rear “tone” switch can be used to give a slight increase in low frequencies by switching → 1 if I ever feel the need.

Here are the settings I've got on the FT-891

GPO Brass Key

GPO Brass Key

An old brass GPO key

A bog-standard brass GPO key, I think. I can't remember where it came from, I picked it up somewhere along my radio journey.

It's quite a nice little key, but I find it a bit “hard” - there's no springiness to the contact closure whatsoever. My HK-708 has a little give, mainly I think due to the spring-loaded ball bearings holding the trunnion rods - but this GPO key is very “rigid”. It sends nicely, once I get used to the feel. I've got it adjusted to my liking, and can happily send at 20+ wpm, but I have to be in the right mood to enjoy using it. If I had to use only one key, and it was this one, I'm sure I'd be happy, but while I have a choice I tend to pick something else.

Seeing how different keys feel does make me wonder about obtaining more, just for the interesting variety of sending feel that's there to be sampled!

Hi-Mound HK-708 Key

Hi-Mound HK-708 Key

My original key from 1982

My HK-708 in all its glory

I got this key while I was still at school, in around 1982, to use for learning to send CW. It was all I could afford at the time, and must have been quite cheap. I've had it, and used it, for over 40 years now, and it's still my main straight key for most QSOs.

Inscribed with my original callsign in about 1983

(and if the recently announced OFCOM licence review goes through unchanged I'll be allowed to revert to G4SLV again, despite living in Scotland. And I can't wait to go back to my “real” callsign!)

I didn't like the original small plastic disc-like knob and at some point, at University in around 1985, I exchanged it for the channel select knob from a Decca Voyager HF SSB Marine transceiver that I had stripped for parts. This is a much larger and heavier aluminium knob which make the key feel much more solid.

The replacement Decca Voyager knob mounting details

The axle (trunnion?) ends are supported by ball bearings, tensioned with springs and the key, for all its cheapness, feels nice and smooth. I've often toyed with getting rid of it and getting something “proper” (a Marconi 365, a PS213, a Junkers, a NATO, or something modern and handmade and brass) but I keep coming back to it and don't see the need to replace it. Of course a small collection of keys is still an option, for interest and variety, but not a necessity while I have this one.

Modern version

I noticed recently that the currently available version of the HK-708 is significantly different to my old one from 40 years ago.

The new one has the same small disc-like knob (which I didn't like) but the main lever is straight, not curved downwards at the knob and I see that the tension spring is forward of the axle, towards the front of the key, so it must be in compression, rather than tension. Whether that makes a difference to the feel, I don't know. I also don't know if the pivots are still ball-bearings or simple bushes. I don't think I'll risk getting a new one to keep on hand in case of need!

Icom IC-7200

Rugged HF/50MHz

Background

This is my 2nd IC-7200. I foolishly sold my original one and very quickly regretted it.
From the Silent Key equipment of Peter GM0CXQ
Obtained 01/06/23

Repairs & Modifications

HM36 Microphone Mod

The current HM-36 microphone supplied with IC-7200 is poorly designed and problems are well documented on the internet.
I carried out the “K1RF/PY3SS Modification” documented here : k1rf_modified_py3ss_hm-36_mic_mod_reva.pdf
The newly modified HM-36 now functions “correctly” with adequate drive for the radio, and a better frequency response.
It is now possible to set Mic Gain < 20 and Compression = 4 and obtain adequate ALC and full power out and a reasonable degree of compression without the need to “Close Talk” the microphone.
It is also now possible to obtain full power out, and some ALC deflection, without use of Compression, by adjusting the Mic Gain accordingly. This was difficult/impossible with the stock HM-36

Fan Mod

I found that on a long (> 1 hour) Olivia QSO at 50W that the rear panel/heatsink reaches 60°C, and even the side-handles reach 43°C
The fans initially turn on with the PTT and run for a few seconds after dropping back to RX
As the temperature increases the fans switch to medium, and then fast speeds while running during TX and also remain running for longer at the switch back to RX
One mod suggests adding a small resistor across the fan switching transistor to keep the fans running slowly at all times, so that duing RX they might remove even more heat before the next period of TX
The mod is here ic_7200_fan_mod.pdf
I carried out the mod, with a 120 ohm resistor and then had a similar long Olivia QSO to compare the temperatures of the rear heatsink and side handles.
Despite the continuous running fan I found that the rear panel still reached 60°C and the handles reached at least 40°C during the TX phase.
They probably cooled down a little more on RX, but not significantly, and not enough that the temperature on TX was noticeably lowered.
There seems no major benefit in the mod, as the thermal design of the radio seems able to cope without it.
There may be a downside though, the fans will now run continuously whenever the radio is turned on, which will cause them to prematurely wear out, or become noisy.
After one night's use I removed the modification and restored the fan control to normal.

Receive functions normally
trace to - pre-drive TX buffer amp transistor - Q1 Main PCB
- No Drive to PA from Main Board
- TX signal present at base of Q1 but no signal at collector
- Q1 2SC4673 sourced from eBay https://www.ebay.co.uk/itm/322993473692
- 07/02/23 : Replaced Q1 and full transmit power restored.

Remote Control

Python module for netradio

Some functions aren't needed for receive only, and should be removed (ptt_on ptt_off etc.). This module originally came from another project (not “object oriented”) and I had to add lots of self statements to the needed functions, ignoring the ones not used for “netradio”. I'll trim it, later, if I remember.

Icom IC-706

anonymous@undisclosed.example.com (Anonymous) — Tue, 30 Dec 2025 09:55:07 +0000

←Rig and Key List

Icom IC-706

Mark 1 - the original “Shack-in-a-box”

HF 100W
6m 100W
2m 10W

Background

From the Silent Key equipment of Peter GM0CXQ

First impressions

In poor condition cosmetically, internally and externally
Intermittent RX performance on several bands, most severely 6m, due to LPF switching relays
No Power cable
- ordered via eBay 24/5/23
No microphone
- ordered via eBay 25/5/23
Not “MARS” modified → no TX on 60m

Initial tests

Sensitivity ok on all HF bands
6m shows intermittent “deafness” after changing bands - LPF relays?
Initially some higher HF bands also showed slow decrease in sensitivity after a few minutes. After transmitting a few times on each band this tendency stopped - have the LPF relay contacts “wiped” themselves clean by carrying more significant signal current on TX?
- 6m still suffers random RF signal loss on RX
TX power ok on all HF bands, and 6m, with 100W FM carrier at setting “H”
All controls work correctly
Fitted FL-223 “Narrow SSB” filter option appears to work (TBC)
Frequency calibration not checked but appears to be acceptable.

Repairs and Modifications

Cleaning

All knobs removed and washed in warm soapy water and all grooves in knobs scraped clean with toothpicks.
Front Panel cleaned, all recesses around buttons/controls cleaned with toothpicks and warm water (being careful….)
Covers from main unit removed and washed to remove build up of dirt from inside and outside.
Inside of main unit vacuumed and blown to attempt to remove as much loose powdery dirt deposits as possible without damaging any connectors or components. Some cleaning of surfaces done where possible.
Re-assembled

6m LPF relays

To cure signal loss on RX I removed the LPF board and was able to pop the clear plastic tops from the 2 relays, used on either side of the 6m LPF section.
Contacts in RL2 and RL3 were cleaned with Contact Cleaner spray, and wiped with paper soaked in cleaner, to remove any dirt/contamination build-up.

Tops replaced on relays and LPF board replaced into radio.
Receive sensitivity now good and does not vary with time, or following band changing.
The relays used on the other HF bands are of a different (more easily sourced) type and can't be opened in this manner. Fortunately they all seem to be healthy at the moment.

MARS TX Mod

To allow use on the 60m band I carried out the simple modification to remove “D59” from the Main PCB, which removes the “TX only in Ham Bands” restriction.
Radio now transmits across the whole HF band, including 60m

Signalink USB

For Digimodes using fldigi and a Signalink USB soundcard requires a simple Cat5 ethernet cable to connect the IC-706 Mic socket to the Signalink USB soundcard. The Jumper information is here : https://tigertronics.com/sl_wirebm.htm

Rigctl / Hamlib

Connect serial RS232 from laptop to IC-R75 and then C-IV cable between IC-R75 and IC-706. The IC-R75 will convert between RS232 and C-IV. Separate C-IV hex addresses means each radio can be addressed individually through one serial connection (/dev/ttyUSB0)

Kenwood TH-D72

Remote Control

The TH-D72 can be used to remotely control a TM-D710. This allows remote control of VHF Frequency/Memory Channel, TX power, CTCSS/DCS tones and to enable/disable cross-band repeat.

The remote control function uses specific DTMF sequences to instruct the TM-D710.

To enable “Remote Ctrl” mode :

Select the correct UHF uplink frequency to match the TM-D710
Turn off the TH-D72
Hold MR and PTT
Turn on the TH-D72

The display will show “Mobile Ctrl”

The TM-D710 must also be put in Remote Control mode.

On the TM-D710

select VHF mode on both sides
turn off the APRS TNC if it's on
set the left side to the wanted VHF Frequency
set the right side to the UHF Uplink/control frequency to match the TH-D72
- the first steps are done by selecting PM5 on my TM-D710
- make sure the left side/VHF is the “active” side by clicking the left volume knob
turn off
hold Rev button
turn on

The TM-D710 should now be in remote mode.

To restore normal operation repeat the same sequence of

Turn off
Hold Rev
Turn on

Successful commands sent to the TM-D710 will receive a “pip pip pip” revertive.

The commands are send using the TH-D72 keypad, remapped as:

1 = DCS On	2 = Tone On	3 = CTCSS On	A = Enter
4 = DCS Off	5 = Tone Off	6 = CTCSS Off	B = CTCSS/DCS Tone
7 = Call Ch. Mode	8 = VFO Mode	9 = Memory Mode	C = Repeater On
* = Down	0 = Power	# = Up	D = Repeater Off

to change VHF Frequency to 145.500
- 8 (VFO Mode)
- A (Enter) 145500 A (Enter)
to change to memory channel 2
- 9 (Memory Mode)
- A (Enter) 002 A (enter)
To turn on Cross-Band Repeat
- C
To turn off Cross-Band Repeat
- D

Once the TM-D710 is in the correct condition - VHF Frequency, tone, power, cross-band repeat - it's possible to restore the TH-D72 to normal operation and use it to access the cross-band repeater and use DTMF tones as normal (eg. to control another system via the repeater). Just exit “Mobile Ctrl” mode on the TH-D72

Turn off
hold MR and PTT
Turn on

You should be back in normal operation mode.

Obviously, to control the TM-D710 again (eg to disable cross-band repeat) simply go back to Mobile Ctrl mode in the same way, and send the required commands.

Vibroplex Champion Bug

Vibroplex Champion Bug

1960 Champion Model

Bought : June 2023, eBay
Cost : £150
Serial Number : 211617
Date : 1960
Plate : D6

Photos

Details

Bought from eBay seller morsecodemad . Arrived 23/6/23 in good condition, with only the dot contacts requiring a cleaning/polishing to make it work perfectly “from the box”

Minimum speed appears to be around 20 wpm, which is a little faster than my Presentation bug which goes down (with both weights at the end) to around 18wpm.

Feels very smooth and much quieter than the Presentation and is very pleasant to use, on the first night's testing on air 23/6/23.

Worked a few stations on 30m with the Champion to check it out and found it working perfectly.

SB7S
UA1ALY
F8GNV
W2IRT
UV5EML
DK6FX

The only issues were with my own technique, which is still developing and needs much more work.

This was my first bug key and has had to have some work to repair damage to the frame. The tapped holes for the screws that hold the frame to the base were stripped, and the frame couldn't be tightened sufficiently to the base. I found the easiest (although not invisible) way to fix it was to drill through the original holes, all the way, and then tap a new thread (M6) and use longer screws to secure the frame to the base. This has spoiled the key's “original” appearance, but made it actually useable as a bug key, which to my mind is much more important. I'm sure old-time professional bug users would make whatever repairs were necessary to keep their favourite keys in operation, caring little of maintaining “originality”. You can see one of the protruding bolts here:
